alternating current (flowing in alternating directions at a certain frequency, measured in Hertz). An example of an AC source is the power supplied by electrical wall outlets. DC (D/C) Impedance | Algorithm In computer terminology, a set of instructions that are followed in a specific order to accomplish some task. An example of a signal processing algorithm is the simulation of ambience in reverb units. | Amplitude W`The strength of a signal level, expressed in dB. Amplitude is interpreted by the ear as volume. Z*Envelope Tremolo Comb filter Modulation | Bandwidth A more general term for frequency response. For example, an audio component s bandwidth may be 20 kHz. The outer limits are defined by a drop in output level of 3 dB. In computer context, bandwidth refers to the maximum possible data throughput.

Crosstalk happens wherever two or more channels are used at the same time and is measured in dB. The greater the figure, the better, because it is the amount of attenuation that counts. For example, if you can faintly hear the drum part on the neighboring vocal track of your multitrack, crosstalk is to blame. Typical crosstalk figures at 1 kHz are about 60 dB for a mixer and 45 dB for analog tape. An acronym for Digital Audio Tape, it refers the small digital cassette tape standard. More properly, the DAT format is called R-DAT, because it involves a rotating head mechanism. Sample rate A/D converter R-DAT s, containing a mix from many individual sources. | crosstalk Default LIn computer terminology this denotes a value proposed by the system for any parameter requiring some set value. Default values are in effect until they are changed by the user and include such things as 4/4 time signature or 120 bpm for many sequencers, or synthesizers always powering up to the first patch (or the last one used). Ratios, such as signal/noise, are given in dB; a tape recorder may have a signal/noise ratio of 60 dB. Z;Crosstalk Cutoff frequency Amplitude Signal/noise ratio Default LIn computer terminology this denotes a value proposed by the system for any parameter requiring some set value. Default values are in effect until they are changed by the user and include such things as 4/4 time signature or 120 bpm for many sequencers, or synthesizers always powering up to the first patch (or the last one used). Dropout A loss or degradation of information on a piece of tape. Dropouts can occur because of dirt, fingerprints, magnetic fields, stretching the tape, or a manufacturing defect. Depending on the severity, a dropout may produce mild effects such as a temporary attenuation of high frequencies (on analog tape) or total loss of signal. On digital tape, small dropouts are compensated for by error correction; but during severe dropouts, the output will be muted. Dynamic range The range of levels that can be represented in an audio system. Measured in dB, it is typically limited by a noise floor and distortion at the outer extremes. The dynamic range of the ear is about 140 dB, limited by the threshold of hearing and the threshold of pain of soft and loud sounds, respectively. Dynamic ranges of tape recorders are about 60-70 dB (analog), 90-100 dB (analog with noise reduction), and 90-96 dB (16 bit digital). R-DAT W see: DAT. Break point see: Envelope. Notch filter see: Filter. Highpass filter see: Filter Lowpass filter see: Filter Bandpass filter see: Filter Partial see: Harmonic. Time stretching see: Time Dilation. Time dilation lA (non-real time) process in which the duration of a signal is lengthened or shortened without affecting its pitch. In music production, time dilation is used to match tempi of samples, such as drum loops, or to fit a selection of sound into a predefined time window, such as a 30 second commercial. To calculate time dilation factors, click the 'sequencing' tab. Time stretching | MIDI file see: Standard MIDI file. Pitch W&The ear's representation of frequency. Z Frequency overtone should be avoided. spectrum Headroom uction), and 90-96 dB (16 bit digital). formant Interpolation WmThe unit in which frequencies are measured. To avoid large numbers when dealing with high frequencies, the multiplication factors Kilo (K, x 1000) and Mega (M, x 1,000,000) are used. Human hearing ranges from about 20-30 Hz to 15-16 kHz, although an optimistic upper range of 20 kHz is often given. In this range, frequencies are interpreted by the ear as pitch. Z Frequency Interpolation Hertz (Hz) mThe unit in which frequencies are measured. To avoid large numbers when dealing with high frequencies, the multiplication factors Kilo (K, x 1000) and Mega (M, x 1,000,000) are used. Human hearing ranges from about 20-30 Hz to 15-16 kHz, although an optimistic upper range of 20 kHz is often given. In this range, frequencies are interpreted by the ear as pitch. Z Frequency Interpolation headroom uThe process of smoothing out discrepancies between adjacent points of a waveform. This is used in error correction circuitry of digital audio devices, like CD's and digital tape players, when discontinuities would be heard as clicks. Other examples include the changes of an envelope generator's level between break points, or the portamento feature on some synthesizers. An acronym for Musical Instrument Digital Interface. A standard digital serial communication protocol that allows compatible equipment to exchange data. Although optimized for musical purposes, the MIDI protocol can be adapted to a variety of applications. Transmitted data for music instruments include such things as notes, expression devices (wheels and knobs), and timing information. ctive sensing Note number Note on/off Aftertouch Breath controller Continuous controller General MIDI Local on/off Omni mode Mono mode Poly mode Multi mode Non registered parameter Off-line Indirectly accessible information. An example of off-line information is a sample you have stored on disk. It is only accessible after it has been loaded into your sampler s memory, at which point it becomes on-line. On-line On-line Directly accessible information. An example of on-line information is a patch on your synthesizer which can be instantly accessed by pushing a button, or sending a program change command. Off-line Overdubof off-line information is a sample you have stored on disk. It is only accessible after it has been loaded into your sampler s memory, at which point it becomes on-line. On-line On-line Directly accessible information. An example of on-line information is a patch on your synthesizer which can be instantly accessed by pushing a button, or sending a program change command. Off-line Overdub An arpeggio in music is a broken chord (notes played one after another as opposed to simultaneously). An arpeggiator scans the notes currently being held on a keyboard and plays them sequentially. Most arpeggiators allow for this stepping action to be extended across several octaves and enhanced in various ways, such as up, down, up/down, random directions, or more complex textures that include some chords and some single notes. d rhythm guitar. Overload Wnc with a previous recording. The term is sometimes also used to distinguish lead instruments, vocals, solos, etc. from basic backing tracks, which contain instruments like drums, bass, piano, and rhythm guitar. Overload Expressed in degrees, it is used to describe an offset in a waveform s cycle. A complete cycle is 360 degrees; therefore, waveforms at 0 degrees or multiples of 360 degrees offset are said to be in phase, while any other number would result in waves that are out of phase. Many mixing consoles provide a switch to invert the phase of a signal by 180 degrees. This is often useful in multiple microphone recording, when signals arrive at two or more mics out of phase, causing frequency canceB llation. Balanced Flanger Quantization Any rounding procedure in digital systems. Very fine quantization occurs in PCM audio systems to represent continuous waveforms as a series of closely spaced numbers. An example of very coarse quantization is the timing correction function of drum machines.rs in PCM audio systems to represent continuous waveforms as a series of closely spaced numbers. An example of very coarse quantization is the timing correction function of drum machines.of phase, causing frequency canceB llation. Potentiometer (pot) A variable resistor that attenuates an applied voltage. Common uses for potentiometers include volume controls, equalizers, or record level adjustments. Quantization Any rounding procedure in digital systems. Very fine quantization occurs in PCM audio systems to represent continuous waveforms as a series of closely spaced numbers. An example of very coarse quantization is the timing correction function of drum machines. | Real time @A process happening in and at the time of delivery. An example of a real time performance would be a pianist playing a song, as opposed to a non-real time or deferred time performance by a band in a multitrack studio, where the music is pieced together over a period of time that is greater than the length of the song. An acronym for Read Only Memory. The content of this type is memory is fixed and may not be altered. Related classes of ROM chips include PROM (Programmable Read Only Memory) which can be stored into once, EPROM (Erasable PROM) whose memory can be erased using high intensity light, and EEPROM (Electronically EPROM) whose memory contents can easily be changed. The difference between these and RAM chips is that they don t need external power to retain data.

Overload Distortion Headroom um. The ear s representation of spectrum is timbre. harmonic #| Threshold Voice DNormally, this refers to a synthesizer channel. For example, a 16 voice synthesizer can play up to 16 notes simultaneously. Confusingly, voice is sometimes used to refer to the number of presets on a synthesizer which is nothing more than a collection of parameters that determine what your hear when you press down a key. DC (D/C) WaShort for Direct Current (a current flowing in only one direction). A battery is a source of DC. AC (A/C) Envelope In audio/synthesis, the evolution of a specific parameter over time. Amplitude and filter cutoff are the most commonly used parameters, changing the volume and the spectrum over time, respectively. The points where the direction of an envelope changes are called break points.

Common filter types include low pass, hi pass, band pass, and band reject (notch) designs, which filter out high, low, and high/low frequencies, respectively. The point at which the frequencies are attenuated by 3 dB is called the cutoff frequency of the filter. Z Frequency break points. Envelope Filter striping subtractivev subtractive synthesisv sustain synthesisv system threshold through timbre time^ dilation stretching transient transposing tremolo unbalanced to as a number of poles , where each pole is equivalent to 6 dB/oct. Filter The Q (for quality) factor of a filter, also called resonance or emphasis, describes the amount of boost around the cutoff frequency of a filter. Cutoff frequency LFO Common slopes are 6, 12, and 24 dB/octave. Sometimes the slope is referred to as a number of poles , where each pole is equivalent to 6 dB/oct. Filter The Q (for quality) factor of a filter, also called resonance or emphasis, describes the amount of boost around the cutoff frequency of a filter. cutoff frequency Comb filter WtA filter with many sharp peaks and dips in its response (making its frequency vs. amplitude graph look like a comb). Phaser Short for Automatic Double Tracking. Using delay processors, ADT simulates the effect of natural instrumental or vocal doubling. Digital delay line Doubling SMPTE An acronym for Society of Motion Picture and Television Engineers. The term refers to a number of synchronization standards, whose pulse frequencies, called frame rates, are 30, 29.97, 25, and 24 fps (frames per second). 30 fps is used in b/w TV (the number of frames actually broadcast per second), 29.97 fps (drop frame), is used in color TV and video, 25 fps is used in European broadcast TV, and 24 fps is used in film. Each SMPTE frame specifies an exact position in hours, minutes, sec color TV and video, 25 fps is used in European broadcast TV, and 24 fps is used in film. Each SMPTE frame specifies an exact position in hours, minutes, seces, sec Expressed in dB, the term is used in two different ways. It may either express the margin between 0 VU and the point at which distortion sets in, or it may indicate the margin between a current signal level and distortion. Because signal levels normally fluctuate, the amount of headroom constantly changes in inverse proportion. To avoid distortion, signal levels are adjusted so that there is always some headroom left. Z/Distortion Signal/noise ratio Clipping Overload ecBfonds, and frames. For example, the frame 02:10:32:09, means 2 hours, 10 minutes, 32 seconds, 9 frames. Short for Frequency Shift Keying. FSK defines a simple form of synchronizing two machines, using two alternating frequencies, usually at 24 pulses per quarter note. In contrast to SMPTE sync, the tempo information in FSK is fixed. SMPTE Frame rate Subtractive synthesis 3The shaping of sound using a rich sound as a starting point and selectively filtering out parts of it. Traditionally, subtractive synthesis is found on analog synthesizers. The basic waveforms (such as sawtooth or square), being rich in harmonics, are subjected to filtering to create a variety of sounds. Additive Synthesis Additive synthesis OThe shaping of sound using combinations of simple sounds for creating complex sounds. Additive synthesis is rarely found in commercial synthesis gear because of the hardware requirements and complexity of parameters. A simple form of additive synthesis can be found on drawbar organs, where each drawbar represents a single harmonic. Subtractive Synthesis Harmonic presents a single harmonic. Subtractive Synthesis Harmonic oltages. In digital audio, DAC s are used to recreate audio waveforms from streams of digital numbers stored on DAT tape, CD s, etc. Short for Digital Signal Processing.

Dither lThe human ear rates noise on analog tape decks much more favorably than the quantization noise on digital systems. In digital audio, dithering is the process of adding small amounts of white noise to the signal. Even though the noise floor increases slightly, the subjective impression of audio quality improves, because quantization noise is effectively masked. Quantization noise Zipper noise see: Quantization noise. Quantization noise Pitch bend Quantization noise Noise introduced as a result of rounding in digital audio systems. Quantization noise increases with low resolutions and poor filter design. Zipper noise Dither noise Quantization noise Pitch bend Ducker A special patch of a compressor and a side chain or key input. During ducking the level of the input is reduced as a function of another signal connected to the side chain input.

Side chain Compressor Dynamic microphone In dynamic microphones, sound is transduced by sound pressure moving a small diaphragm attach to a moving coil within a magnetic field. The normal directional response of a dynamic mic is the cardioid pattern. Condenser Microphone Early reflections 7Early reflections (ER) describe the phase of a sound between the initial (dry) sound and the onset of reverberation. ER may be heard distinctly, if they are spaced sufficiently far apart, e.g. in a very large hall with highly reflective surfaces. Some digital reverbs offer precise control over ER parameters. Reverb Exciter dynamic microphone The Q (for quality) factor of a filter, also called resonance or emphasis, describes the amount of boost around the cutoff frequency of a filter. Cutoff frequency Filter Short for Low Frequency Oscillator. s are used in synths and samplers to modulate a sound. For example, an LFO may be applied to frequency (pitch) to create a vibrato, or to amplitude (volume) to create a tremolo. Sample and hold Tremolo Vibrato Modulation In audio terms, modulation means change. When parameters such as frequency, amplitude, spectrum, etc. are changed, they are being modulated. imes the slope is referred to as a number of poles , where each pole is equivalent to 6 dB/oct. Filter Frequency WxAn effects device that generates artificial harmonics and mixes it with the input signal, resulting in a brighter sound. Harmonic distortion Expander gAn effects devices which increases dynamic range by attenuating low level signals. Expanders are often used to clean up noisy tracks, based on the assumption that the noise will be quieter than the desired signal. When the signal source stops, the expander can reduce the volume of the noise. When the source is present, it will (hopefully) mask the noise. Z*Compressor Compander Side chain Noise gate Standard MIDI file A standard that describes the data format for MIDI sequences.

Since no ground connection is perfect, the voltage difference between different ground connections creates a current which is audible in the form of hum and buzz. Noise DI box yphony. Ground loop Short for Inches Per Second, ips measures the speed at which tape moves past the heads of an analog tape recorder. An increase in tape speed provides better frequency and transient response on analog machines, and a reduced probability of dropouts on digital machines.

Smaller consoles usually have only one (if any) insert points which are connected just after the input gain. Larger consoles offer another insert point after the EQ section. Limiter An effects device which reduces the dynamic range to a safe level by preventing overload during signal peaks. Compressor are essentially the same as limiters. When the compression ratio is greater than about 20:1, it is generally referred to as limiting rather than compression. Compressor Local on/off HA software switch which allows the connection (local on) or disconnection (local off) between a MIDI keyboard and its internal sound generator. Local mode is usually set to off for sequencing purposes, so that a sound is not played twice (once from the keyboard and once by the sequencer echoing the note back to the keyboard). ather than compression. Compressor Local on/off WfShort for MIDI time code, it is the equivalent of SMPTE time code, embedded into the MIDI data stream. SMPTE Multitimbral #A term used in the context of MIDI instruments, which describes the instrument s ability to play different sounds on different MIDI channels.

Z Equalizer Group A buss on a mixing console carrying a submix from several sources, whose output level is controlled by a dedicated fader. The group outputs usually feed the inputs of the multitrack recorder. see: Non Registered Parameter. Non registered parameter Wgistered parameter Phaser #An effects device which passes a duplicate of an input signal through a comb filter and mixes it with the input signal. The bands of the filter are swept, usually by an onboard LFO. The resulting phase cancellations at changing frequencies give the phasing effect its characteristic sound. see: Pre fade listen. Pre fade listen nA monitoring mode provided on most mixing consoles that lets the engineer listen to only those sounds whose PFL switches are engaged. In contrast to solo mode, PFL is non-destructive to the mix and the sounds are monitored raw, i.e. as they enter the board, but after the input gain control. PFL monitoring is used to optimize the signal level to its input channel. After fade listen SoloSolo ere all channels are muted except those whose solo function is engaged. This allows the engineer to focus on specific instruments in a mix, along with any applied effects. PQ codes are subcodes written along with the audio data to a CD and include such things as track and index markers, table of contents, total running time, etc. Ring modulator An effect device which takes two inputs and outputs the sum and difference of the signals.

Loops can help conserve memory in samplers, but sometimes the technique becomes obvious, because of dynamic or timbral differences between the loop points. crossfade looping crossfade looping Tremolo W6Periodic modulation of amplitude, usually with an LFO. Transposing OTo shift all notes of a musical piece by the same amount which is normally specified in semitones. For example, a setting of +7 on a keyboard would transpose the keyboard up a perfect fifth, so that pressing middle C will now actually play a G above that. Click the 'circle of fifths' tab for help with transposing to different keys. Unbalanced CA wiring system where there are only two leads in a cable, one being hot (+) and the other being ground. Unbalanced wiring is susceptible to picking up noise which is induced into the cable from outside sources, such as power supplies or radio stations, and increases with factors like cable length and poor cable quality. Balanced ctors like cable length and poor cable quality. Balanced Velocity On MIDI keyboards, velocity is the speed at which a key is pressed down. This can be used to control volume and/or other parameters. Velocity has a resolution of 127 steps (with a velocity of 0 being equal to a note off command) and is interpreted by MIDI devices and sequencers along with note information. Most keyboards are velocity-sensitive (measuring velocity). Those that are not, output every note with a velocity of 64 unless otherwise specified.

Dropping in and out of record mode to rerecord small portions of a previous take. Punching in and out can be done manually or using pre-defined locator points for pinpointing the exact position. Release Similar to decay, release describes the final phase of a sound during which the sound dies away. We normally refer to release, if a sustain portion has preceded the release, otherwise it is called decay.

Typical waveforms include sine, triangle, square, and sawtooth waves. Bias frequency Pan (Panorama) describes the relative left/right position in a stereo field. The pan position is usually controlled by a knob on the mixing console, but in MIDI modules it can also be controlled by MIDI messages (normally controller # 10). print through Active sensing 4A MIDI message that confirms proper communication status to the receiving device. If the stream of active sensing messages is interrupted (e.g. by power failure or cable disconnection), the receiving devices turns all notes off. This message is ignored by some devices and generally thought of as outdated. Z/Attack Decay Release Envelope generator Looping Looping .The process of defining a start and an end point in a sample and repeating this section.

Fragmenting A computer disk is said to be fragmented when the files which are stored on it occupy discontiguous space. This happens when some files are erased and space is freed up which is later used to partially write new data to. Frequent erasing and writing of small files significantly contributes to a fragmented disk. Depending on the severity of the fragmentation, this can lead to slower operation or even hardware failure. Fragmented disks can be defragmented using specialized software. Defragmenting Fundamental WcThe portion of the sound that we hear as pitch. The fundamental is also called the first harmonic.

Ears are very sensitive to formants which are important in recognizing speech and instrumental timbres. The human voice and vocal cavities change formants in shaping of vowels. Harmonic Frequency response WFAnother word for bandwidth, usually in the context of audio equipment. Z Bandwidth Harmonic vA specific frequency component of a sound. The first harmonic (i.e. what we hear as the pitch) is called fundamental; higher ordered harmonics contribute to the spectrum or timbre.

Essentially the same as overload, this term is commonly used to refer to tape distortion. Overload Distortion Signal/noise ratio Expressed in dB, it is similar to dynamic range, except that the range between the noise floor and 0 VU (rather than distortion) is measured. Typical signal/noise ratios are about 55 dB for an analog tape deck without noise reduction and 90 dB for 16 bit digital tape. In order to look better on paper, some consumer equipment may give you the dynamic range spec as the signal/noise ratio.

The slope or curve of the filter determines how much the frequencies are attenuated. It is expressed in dB/octave. Common slopes are 6, 12, and 24 dB/octave. Sometimes the slope is referred to as a number of 'poles', where each pole is equivalent to 6 dB/oct. Filter Hertz (Hz) mThe unit in which frequencies are measured. To avoid large numbers when dealing with high frequencies, the multiplication factors Kilo (K, x 1000) and Mega (M, x 1,000,000) are used. Human hearing ranges from about 20-30 Hz to 15-16 kHz, although an optimistic upper range of 20 kHz is often given. In this range, frequencies are interpreted by the ear as pitch. Frequency Bandwidth AC (A/C) Frequency Bandwidth AC (A/C) A device which can automatically move to a specific point in a recording. On tape machines, this involves automatic activation of forward or rewind functions, and stopping the tape at the locator point. Locator Aux send IA buss on a recording console which is used to feed selected sources to an external or internal effects device. Aux sends may be set to either 'pre-fade', where the signal level is only determined by the setting of the aux control, or 'post-fade', where the signal level is also proportional to the setting of the channel fader. Balanced *A balanced line uses three conductors: plus, minus, and shield. When both the sending and receiving device are wired in a balanced manner, any noise which is picked up by the cable is canceled out at the receiving end, because the plus and minus lines are out of phase with respect to one another. Z&Unbalanced Common mode rejection Phase QA selectable signal level above or below which some function is activated. Typical applications include noise gates and compressors, which affect an input signal below and above the threshold, respectively, and sampling keyboards whose recording function may be automatically initiated upon receiving a signal level above the threshold. Z!Compressor Expander Noise gate $| Transient A sudden burst of energy in an audio signal, such as from a drum hit. Transients often don t add much to the perceived loudness of a signal, but can easily overload tape or electronics, causing distortion. Distortion A unit of measurement that compares two values. For any quantity given in dB, it must be referenced to some other quantity. If we say that a sound is 100 dB loud, we are really saying 100 dB spl (sound pressure level), which is 100 dB greater than the average threshold of hearing. Audio signals are measured in dBm, where 0 dBm = 1 milliwatt into 600 . Ratios, such as signal/noise, are given in dB; a tape recorder may have a signal/noise ratio of 60 dB. ZeCrosstalk Cutoff frequency Headroom Normalizing Dynamic range Filter Amplitude Signal/noise ratio In synthesizers, envelope generators are used to create envelopes of arbitrary shape and are described in terms of their level and time segments. Most envelope generators provide at least four segments and are usually called ADSR generators, which stands for Attack, Decay, Sustain, Release. Others may give you an unlimited number of segments. The points where the direction of an envelope changes are called break points. Z*Envelope Attack Decay Sustain Release Filter PIn audio, a circuit passing certain frequencies while rejecting others. Common filter types include low pass, hi pass, band pass, and band reject (notch) designs, which filter out high, low, and high/low frequencies, respectively. The point at which the frequencies are attenuated by 3 dB is called the cutoff frequency of the filter. ZeEnvelope Notch filter Cutoff frequency Comb filter Wah-Wah Subtractive synthesis Quantization noise A microphone s directional response pattern which is equally sensitive to sounds from the front and the back. Sound arriving from the sides is rejected. This pattern is often selectable as one of several patterns on condenser microphones. Z1Directional pattern Cardioid Pattern Omni pattern Flanger An digital delay based effect which makes a copy of the input signal and delays it slightly (between about 1 and 10 milliseconds), inverts the phase, and sweeps the frequency. The resulting sweeping sound is caused by frequency cancellation. The term dates back to the days when the effect was created by recording the sound onto two identical tape recorders while the engineer applied pressure to one of the deck s flanges (sides of a reel), causing pitch fluctuations.
