Is there an open source library that supports AIFF?

Cheers,

You can use same as for WAV
It is PCM.

Lars:
OS/2 already contains an IOProc for AIFF as well as IFF, it's implemented in aiffproc.dll.

Also - https://smedley.id.au/tmp/mmiovorbis-O0-20221031.zip is built with GCC 12.2.0 - but with Optimisation set to -O0 to minimise any optimisation.

Hi

I finally got some time to test this packages. I'm starting with "mmaudiopack-20221031.zip"

Here is the install with MINSTALL, I think that everything went normal.

--- Code: ---MINSTALL - Multimedia Installer (CLI/CID) - by Kiewitz

Active package is : 'MMAudio Pak 2'

1 - 'MMIOFLAC' (Selected)
2 - 'MMIOVorbis' (Selected)
3 - 'MMIOMP3' (Selected)

Please select/deselect group(s), ENTER to install or ESC to exit

Are you sure to install this package? (ENTER to confirm)
 -> C:\MMOS2\DLL\mmiomp3.dll
 -> C:\MMOS2\DLL\mmiovorb.dll
 -> C:\MMOS2\DLL\mmioflac.dll
Custom-Terminate-API: Thread opened
Custom-Terminate-API: Thread closed
Return-Code FE00 (CID: Success, system should reboot)

[C:\HOME\DESKTOP\MMAUDIOPACK-20221031]


--- End code ---
- Rebooted

Now I want to know what will be some usefull testing procedure.
- I grabbed and MP3, OGG and FLAC test files from the internet.
- WPS Play: OGG and FLAC tested fine with "WPS Play" (double click). MP3 is not register by default on the WPS, gotta check on that.
- MPPM.EXE: The MP3, OGG and FLAC test files reproduced fine on MMPM.EXE.

What other tests do you suggest for it ? I have no problems to report for the moment.

Regards

Paul Smedley:
Hey Martin, thanks for testing. You could test audio conversion, but suspect you'll see the same issues David reported. I need to get around to investigating that !!

Remy:
Hi,

May it be possible to have WAV (24bits - 44100 as well 24bits 48000) supported by mmaudiopack ?

Regards
Rémy
