-
- 1.32
- · AHI is no longer a library, but a device ("ahi.device").
- · Doubled volume for stereo modes without panning.
- · Changed the audio IDs for paula and wavetools.
- · Moved the audio drivers from LIBS:AHI to DEVS:AHI.
-
- 1.286
- · 'Cancel' text in the requester defaulted to the swedish word for
- cancel. Oops.
- · AHI_GetAudioAttrsA() now takes 3 arguments instead of 2.
- · Improved mixing rutines for AHIST_M8U samples a bit. More
- changes are needed!
- · AHI_SetEffect() now only takes 2 arguments, and cannot be called
- from interrupts anymore.
- · Added the first effect: AHIET_MASTERVOLUME.
- · Removed some useless mixing routines and added a few other.
- When not using panning things should be faster now.
- · Added a new database tag: AHIDB_Realtime.
- · AHI_ControlAudioA() now returns an error code.
- · More new data base tags: AHIDB_MaxPlaySamples,
- AHIDB_MaxRecordSamples and AHIDB_MixFreq.
- · The way audio drivers tell ahi.device it can be used for
- recording has changed.
- · Added second effect: AHIET_OUTPUTBUFFER.
- · Sample frequencies can now be up to 131071 Hz, which should be
- enough for most users.
- · Improved most of the mixing routines. Fixed some bugs in the 16
- bit routines aswell.
- · The requester now has menus and is keyboard controllable.
- · Yet another new database tag: AHIDB_FullDuplex.
- · Samples can now be played backwards (AHIST_LOOP sounds, however,
- cannot. ).
- · I had to change the AHIAudioCtrl structure a little. Old
- drivers will NOT work any longer - they will probably crash!
- Hey, it's still a beta version - I'm allowed to do such things!
- · The requester tags has been redefined, a recompile is
- neccessary.
- · Removed a memory leak in AHI_AudioRequestA().
- · New tags for AHI_ControlAudioA(): AHIC_MonitorVolume and
- AHIC_MonitorVolume_Query.
- · Removed the AHIDB_MixFreq tag in AHI_GetAudioAttrsA() and added
- AHIC_MixFreq_Query for AHI_ControlAudioA().
- · Cursor keys can now control the audio mode requester.
- · Added 32 bit mixing routines with linear interpolation.
-
- 2.4
- · New field in the AHIAudioCtrlDrv structure: ahiac_BuffType.
- · Rewrote parts of the mixing routines. Sometimes they read one
- sample to much, causing clicks. Hopefully they work now. The
- new routine is a little faster, by the way...
- · Fixed the 32 bit linear interpolation mixing routines; they
- ALWAYS read at least one sample too much, sometimes two.
- · Loads of new tags for AHI_ControlAudioA(): AHIC_InputGain,
- AHIC_InputGain_Query, AHIC_OutputVolume, AHIC_OutputVolume_Query,
- AHIC_Input, AHIC_Input_Query, AHIC_Output, and AHIC_Output_Query.
- · Even more new tags for AHI_GetAudioAttrsA():
- AHIDB_MinMonitorVolume, AHIDB_MaxMonitorVolume,
- AHIDB_MinInputGain, AHIDB_MaxInputGain, AHIDB_MinOutputVolume,
- AHIDB_MaxOutputVolume, AHIDB_Inputs, AHIDB_InputArg, AHIDB_Input,
- AHIDB_Outputs, AHIDB_OutputArg and AHIDB_Output.
- · Increased the maximum frequency a sample can be played at to
- 262143 Hz.
- · Previously, the requested number of channels was rounded to an
- even power of two, i.e. an 18 channel song actually used 32
- channels. This is no longer the case.
-
- 2.23
- · Fixed a bug in AHI_GetAudioAttrsA(): Strings was not always
- NULL- terminated.
- · CloseDevice() trashed some registers it shouldn't. Not so
- anymore.
- · By mistake I used the function graphics.library/SetRPAttrs() in
- the requester code, which caused AHI to crash on pre-39 machines.
- · Fixed some bugs in the autodocs
- AHI_AllocAudioA()/AHIA_RecordFunc. Note that the RecordFunc must
- return NULL from now on!
- · All PlayerFreq related values should now be Fixed instead of
- ULONG. A kludge has been added to keep old programs going for
- some time.
-
- 3.861
- · Small bug fix in the requester code.
- · AHI_DEFAULT_ID as AHIA_AudioID tag data (AHI_AllocAudioA())
- didn't work.
- · New function: AHI_PlayA().
- · MC68000-version added.
- · New mode for audio drivers: AHISB_CANPOSTPROCESS.
- · Bug fix: Turning off the AHIET_OUTPUTBUFFER effect resulted in
- an endless loop.
- · Surround support added.
- · New effects: AHIET_DSPMASK and AHIET_DSPECHO.
- · New function: AHI_SampleFrameSize().
- · New (private) functions: AHI_AddAudioMode(),
- AHI_RemoveAudioMode() and AHI_LoadModeFile().
- · AddAudioModes does not have to be run before AHI can be used
- anymore. When 'ahi.device' is loaded, it will check if the audio
- mode database is loaded. If not, it will automatically scan
- DEVS:AudioModes/ for mode files and add them.
- · Rewrote the last three non-critical functions in C instead of
- assembly.
- · Added the new tag AHIB_Dizzy to AHI_BestAudioIDA().
- · New "effect": AHIET_CHANNELINFO.
- · The first two device commands added: CMD_READ and CMD_WRITE
- · The (obsolete) MultiLoop feature is not totally gone.
- · Removed a bunch of mixing routines that almost never were used
- anyway.
- · AHI_LoadSound() does not handle unsigned 8 bit samples anymore.
- You'll have to convert such samples before they can be played
- from now on.
- · Added Storm C include files.
- · More device commands: CMD_RESET, CMD_STOP, CMD_START and
- CMD_FLUSH.
- · Stereo sounds can now be used too.
- · Max frequency for AHI_SetFreq() increased once again: 1048575.
- · Added two functions to calculate CPU usage and avoid lockups
- (ahiac_PreTimer and ahiac_PostTimer).
- · Localized it.
-
- 3.948
- · AHIR_Locale should work now.
- · AHIDB_MaxChannels didn't work in AHI_BestAudioID().
- · The users preferred audio mode can now be selected in the
- requester, by setting AHIR_DoDefaultMode to TRUE.
- · Added an infowindow to the requester.
- · All functions that take an audio mode id as input can now use
- AHI_DEFAULT_ID as well.
- · CMD_READ should actually work now. I hope.
- · Faster 16 bit mixing of 16 bit samples when using a "fast" mode.
- · New flag for OpenDevice(): AHIDF_NOMODESCAN (private).
- · (Wrote user docs.)
- · (Updated "Programming Guidelines".)
-
- 3.1080
- · CMD_STOP and CMD_START should work better now?
- · The freqgadget wasn't ghosted if the requester was opened with
- audioid set to AHI_DEFAULT_ID. Now it is.
- · Up to 4 device units are now available.
- · No more alignment restriction for CMD_WRITE.
- · Removed IORequest size check for OpenDevice(AHI_NO_UNIT) in
- order to make some programs that open V3 without a valid V3
- AHIRequest work.
- · AHIST_INPUT redefined.
- · Rewrote AHI_LoadSound() and AHI_UnloadSound() in C.
- · Playing 16 bit stereo samples in mono-not-fast mode did not
- work.
- · AHI_BestAudioID() and FilterTags in the audio mode requester had
- got the FullDuplex flag all wrong.
- · The audio mode requester can now handle AHIR_PubScreenName set
- to NULL, meaning that is should open on the default public
- screen.
- · The echo routines is now rewritten. "Fast echo" routines added.
- "No-cross-Full-mix" too.
- · I tried to get AHIST_INPUT working, but I couldn't make the
- recording and playback sync. I suspect the problem is in the
- Paula driver, but I don't know...
-
- 3.1091
- · Major bug in the device interface code fixed. It could crash,
- and never used more that one channel.
- · Amiga E modules added.
-
- 4.20
- · Bumped version to 4.
- · (Transformed "Programming Guidelines" into "AHI Developer's
- Guide".)
- · Added AHIE_HALFDUPLEX error code.
-
- 4.26
- · Some tweaks...
- · AHIET_DSPMASK didn't work! Now it does.
-
- 4.99
- · Fixed a race condition when playing small chunks with CMD_WRITE.
- · Fixed the problems with unreplied IO requests.
- · Fixed a lockup problem with CMD_START (it's still far from
- perfect).
- · Fixed some problems in AHI_BestAudioIDA().
- · ahiam_AudioID and ahiam_MixFreq are now left unchanged if the
- user cancels the audio mode requester.
- · Added optional clipping when using master volume > 100%. So
- there.
- · The functions that returned BOOL (AHI_GetAudioAttrsA() and
- AHI_AudioRequestA()) now sets all 32 bits and not just the lower
- word of the return code (BOOL is only 16 bit).
- · Bug fixes in the "normal" mixing routines (not fast or hifi).
- · Much faster HiFi routines.
-
- 4.109
- · Oops! I had some debug code left in the device (flashing
- backgrounds, anyone?)...
- · Added 68060 version.
-
- 4.158 (R4.14)
- · AHI_LoadSound() now returns an error if the user tries to play
- unsigned samples in HiFi modes (i.e., I removed the
- AHI-Noteplayer-for-Delitracker kludge).
- · AHI_LoadSound() always returned 0 if the driver overloaded the
- function. Now it returns the correct value.
- · AHI_SetEffect() would return 0 even if the driver overloaded the
- function.
- · Fixed an overflow error in the HiFi-routines.
- · Removed distortion when playing sounds backwards in HiFi mode.
- · CMD_START was never executed... Sigh.
- · NSCMD_DEVICEQUERY didn't know about CMD_START and CMD_STOP.
- · Echo will no longer trash memory.
- · Bug in the 32 bit stereo echo routine removed.
-
- 4.164
- · Bug fixes in the HiFi routines. There was also debug code left
- (!), that disabled stereo for some 16 bit samples.
- · Booleans variables in the tag lists and the audio mode database
- are now compared using logical XNOR instead of equality.
-
- 4.165
- · Removed an accidental KPrintF() from the device code.
-
- 4.180 (R4.15)
- · Improved debugger output.
-
-
- AHI preferences
- ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
- 0.1
- · There is now a prefs program, written by Ruediger Sopp, that can
- be used to select default audio mode, frequency etc.
-
- 1.0
- · New preferences program, rewritten from scratch. This one
- (barely) fits on a 640×200 screen using Topaz 8.
-
- 4.3
- · Bumped version to 4.
- · Localized it.
- · "Reset to Defaults" didn't reset the Global Options.
- · "Restore" fixed (always loaded ENV:Sys/ahi.prefs, even if
- invoked with a FROM argument.
-
- 4.5
- · New global option: Mastervolume with(%|out) clipping.
- · MUI version written by Stéphane Barbaray added.
- · Small bug fix in the MUI version, and CTRL-C also works now.
-
-
- AddAudioModes
- ¯¯¯¯¯¯¯¯¯¯¯¯¯
- 1.1
- · AddAudioModes rewritten. New switch: REMOVE.
-
- 1.2
- · AddAudioModes got another switch, DBLSCAN, which tries to open
- and then immediately close a native, double-scan screen. At
- least CyberGraphX keeps the scan rate when ECS/AGA screens are
- closed, so this enables >28 kHz sample rates for graphic card
- owners. My guess is that this requires V39 or greater to work,
- but it should work with both ECS and AGA. Don't forget to
- install a doublescan monior driver if you don't already have one.
-
- 1.5
- · AddAudioModes DBLSCAN now scans the audio mode database for the
- screen mode that allows highest sample rates.
- · The device is now opened with the AHIDF_NOMODESCAN flag.
-
- 4.1
- · Bumped version to 4.
-
- 4.2 (R4.17)
- · Added hardware-banging code to force VGA mode.
-
-
- AHI-Handler
- ¯¯¯¯¯¯¯¯¯¯¯
- 1.8
- · Changed the priority of the AUDIO: handler to 5.
-
- 4.1
- · Bumped version to 4.
-
- 4.2
- · Much improved error handling.

- · Added sampler emulation. This means that this driver can now be
- used to simulate a sound card with sampler. Just select an audio
- file when the requester pops up. (This feature is only for
- programmers and requires OS 3.0 or higher, because
- datatypes.library is used to load the audio file.)

- forgot the start address.
-
- 2.4
- · Can now use the Aura sound card as sampler instead of one in the
- parallel port.
-
- 2.5
- · Better handling of the Aura sampler. The driver is now defined
- to have two inputs, instead of using two separate mode files.
-
- 3.0
- · Added protection against CPU overload.
-
- 3.1
- · The variable AHIpaulaFilterFreq is now checked when the audio is
- allocated.
-
- 4.1
- · Bumped version to 4.
-
- 4.2
- · This is unbelievable, but I had swapped the left and right
- channel!
-
- 4.5
- · Crashed related to the PCMCIA code removed. Oops.
-
- 4.6
- · Better checks for >28 kHz modes.
-
- 4.7
- · Added variable AHIpaulaSampleLimit, to remove the screen mode
- checks.
-
- 4.8
- · Better checking of videomode with Picasso 96 (req. 1.18+).
-
- 4.10

- deallocated.
- 4.21 (R4.17)
- · Added the AHIpaulaFakeMixFreq environment variable.
- 4.23 (R4.18)
- · Much improved timing! This driver should now behave exactly like
- the filesave driver (and most sound card drivers as well),
- provided AHIpaulaFakeMixFreq is set to 1, of course.

- driver. Not anymore.
- · ARGH!! The doublebuffer.c example used an incorrect formual for
- calculating the buffer size!
- · Moved the Delitracker noteplayer out of the developer archive
- (what's the point when it doesn't include any source?).
- · The protracker replay code called AHI_ControlAudioA() every
- interrupt, since I fotgot to clear ptd_NewTempo.
