ADVANCED SIGNAL PROCESSOR UPGRADE LATEST INFORMATION
====================================================
This file contains information not available during the printing of
the manual. Please read them before you proceed with any installation
procedure.
This file contains the following sections:
1. Software Installation
2. Advanced Signal Processor
3. Introducing QSound
1. SOFTWARE INSTALLATION
The installation program, INSTALL.EXE will modify your CONFIG.SYS
file. The original file will be renamed with a B~K extension.
The original file WINSETUP.INF in your \SB16 directory will be
renamed with a I~F extension.
The procedure for installation is as follows :
a. Run the program INSTALL.EXE from DOS prompt and follow the
instructions on the screen.
b. REBOOT YOUR SYSTEM.
You will now be able to make use of the Advanced Signal Processor
chip to perform various digital signal processing functions like
data compression and decompression in real-time without making
heavy demands on your system's CPU.
Note : For those files that are being updated, the original copies
can be found in the \SB16\BACKUP directory.
2. ADVANCED SIGNAL PROCESSOR
All the CSP files (*.CSP) MUST be located in the Sound Blaster 16
\CSP sub directory (example C:\SB16\CSP) when using any
compression technology.
3. INTRODUCING QSOUND
QSound is a revolutionary sound placement technology that generates
realistic and accurate sound spatial distribution. With QSound,
you can generate a 180-degree soundscape. It is incorporated into
the SB 16-Advanced Signal Processor audio card without any hardware
addition or modification. QSound requires only a traditional
stereo playback system for reproduction.
Setting Up Your Speakers for QSound
To achieve optimum QSound imaging, you must take note of the
following setup instruction.
1. Place the speakers on the same plane. They must be placed at
the same height and face you at the same angle.
2. Make sure that the speakers separation is between 16" and 72".
When the speaker separation is 16", the listener should be at
the center, about 20" away from the speaker plane. As the
speaker separation increases, the listener's distance from the
speaker plane should also be increased proportionally.
You may run QSALIGN.EXE to locate the optimum distance.
If you are setting up your system in a small enclosed room,
make sure that you place the speakers 3 feet away from side
walls.
3. If you are using a hi-fi system, make sure that for both
speakers you connect the red (positive) and black (negative)
speaker wires to the respective positive and negative
connectors of your amplifier.
4. If the speakers have separate volume control, set the left and
right speakers volume level as equally as possible. If your
system has a single balance control, set it to the center or
balanced position.
5. Adjust the speaker volume to a reasonable level. If the volume
is too high or loud, the reflected signal may neutralize the
QSound effect.
QSALIGN
QSALIGN helps you align your speakers correctly. To execute this
program,
- go to the QSOUND sub-directory (eg. C:\SB16\QSOUND ).
- type QSALIGN, then press [ENTER].
This program pans a sound source at the extreme left and the
extreme right.
To listen to the left playback, press the left arrow key. To
listen to the right playback, press the right arrow key.
After pressing each key, you should hear the sound source coming
from a position outside the range of the two speakers. With the
speakers separation within the range of 16" to 72", you can
continue to press the left or right arrow key, and adjust your
distance from the speaker plane to find the sweet spot to achieve
an optimum QSound image.
Press the [ESC] key to quit from the alignment program.
Note: If you have set up QSound properly but are not able to
hear the QSound effect, your speakers may be receiving
out-of-phase signals. Try again with another pair of
speakers. If you are using a hi-fi system, make sure you
have connected the speakers correctly. (see Setting Up
Your Speakers for QSound step 3)
QSound in DOS
Within the DOS environment, we have provided an auto running demo
- QSDEMO.EXE.
To execute this demo program,
- go to the QSOUND sub-directory.
- type QSDEMO, the press [ENTER].
The demo program will first introduce QSound and then display a
background picture. Next, you will see an object appear randomly
at different positions on the screen. As the object appears at
each position, you will hear the sound coming from that position.
When the sound source is at the extreme left and right position,
you will not see the object on your screen.
Press [ESC] to end the demo.
QSound in Windows
In the Windows environment, we have provided a QSound Control
Panel which allows you to use and experiment with QSound effects.
To activate the QSound Control panel,
- double click the QSound icon in the Sound Blaster 16 group.
By default, the QSound effect is on (enabled) as indicated by a x
in the QSound On check box. Click on the check box to disable
QSound. The x will disappear indicating that QSound is off or
disabled.
Note: The QSound effect cannot be enabled or disabled during a
wave playback. Then enabling or disabling of QSound effect
will only affect the next wave playback.
The QSound Control panel is divided into two sections:
- Left Output Channel to control QSound settings for the Left
channel.
- Right Output Channel to control QSound settings for the Right
channel.
Note: For mono sound sources, use the Left Output Channel only.
When using QSound Control Panel, you have the choice of manually
setting the position of the sound source by dragging the respective
Position Slider to the desired position. Or, you can also use the
Automatic Panning feature.
To use Automatic Pan
- click on the Automatic Pan drop-down list box.
You have the choice of panning from Left to Right (L -> R), Right
to Left (L <- R), sweep between Left and Right ( L <-> R) or switch
off the automatic panning (click on None).
You may change the automatic pan duration by clicking on the secs
spin-button to increase or decrease the time. Pan duration is the
time taken to move from one end to the other. If the time set for
the automatic pan is less than the playback time of the sound
source, the sound source will be at the final position of the
automatic pan for the remaining time.
Click the Quit button to close the QSound Control window.
The QSound Control panel has a set of factory default settings
when you first activate it. All subsequent changes to the QSound
Control panel will be saved as the new default upon your exiting
the QSound Control panel.
The QSound Control panel works in low priority mode. When an
application such as Creative Mosaic uses QSound, the control panel
becomes inactive. When you quit the application that uses QSound,
the control panel will become active again.
Experiencing QSound in Creative Mosaic
Our latest version of Creative Mosaic has been modified to support
QSound. As you move a tile to the left or right, the sound source
will be coming from the extreme left or right respectively.
Observing Some Tips When Using QSound
Creative's QSound implementation supports PCM wave playback of 8kHz,
11kHz, 22kHz and 44.1kHz only.
Please take note that a normal stereo file having similar signals
at the left and right channels, fully panned left or right, will
not produce good QSound effect.
Note : QSound effect only applies to digitized sound (*.WAV file)
but not MIDI output (*.MID files) or CD output.
