Rebuilds of MM Audio Pack

[Paul Smedley]

I had to set the test programs, especially the pipe tests, to use binary mode with flac.
Does the audio pack support AIFF?

Yeah as a quick kludge I might just link with -Zbin-files and see if it fixes it...

[Paul Smedley]

Hey Dave,

Does the audio pack support AIFF?

Is there an open source library that supports AIFF?

Cheers,

Paul.

[Dave Yeo]

I was thinking of Flac. Of course there is libavcodec (FFmpeg) that supports most anything, though last I checked, not encoding to MP3.
In flac/test are some example aiff 's, also wave 64.

[Paul Smedley]

OK -Zbin-files didn't help... I did change to linking with -static-libgcc, and now see that the first exception in audconv.exe is now in mmiovorb.dll - the map file should help understand where it's trapping, and I can also enable debug logging.

Will do this on another day, feeling a bit sore tonight after having a couple of biopsies taken from some moles on my back!

Perhaps try linking against libcx?

Sounds painful, part of living in Australia I guess. Hopefully they're just regular moles. Good luck.

You can use same as for WAV
It is PCM.

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

https://smedley.id.au/tmp/mmaudiopack-20221031.zip updates to the latest ogg, vorbis and flac libraries - and uses GCC 12.2.0

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: [Select]

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]

- 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

That is already supported with installing USBAUDIO package. It adds the necessary SPI info so that MMPM can understand this new Samplerate/numchannels/bit depth format.

Here is a list of what formats have been added by now:

Additionally, of course, the sound driver has to understand the format. For the USB audio drivers, Wim implemented a (lengthy) routine to convert sample rate/num channels/bit depth to the closest match of what the USB audio HW supports. Works perfectly.
As far as I can tell UNIAUD typically supports 8000 Hz, 11025 Hz, 22050 Hz, 44100 Hz, 48000 Hz (cannot remember what bit depths are typically supported). The support depends on the actual audio HW as UNIAUD is a generic driver covering all sorts of different audio HW.

Nice to know.

[Dariusz Piatkowski]

That is already supported with installing USBAUDIO package. It adds the necessary SPI info so that MMPM can understand this new Samplerate/numchannels/bit depth format....

...even if I'm not using a USB based audio device?

[Martin Iturbide]

Hi Dariuz

Lar's told me on some email time ago.

"Even though the name implies something different, USBWAV.DLL has no direct relationship to USBAUDIO.
It is a standalone DLL containing multiple IO Procs and codecs that work on any OS/2 system with MMPM.
The name is a leftover due to historical reasons."

I think it does not depends on USB.

Yes. The addition of new data subtypes (samplerate/numchannels/bit depth combination) to MMPM (done via SPI.INI) is independent of any specific audio driver but is a necessary precondition to use that combination at all.
But of course, the audio driver also has to support that sample rate/bit depth/numchannels combination.

In short, the update package to SPI.INI contained in USBAUDIO will satisfy the prerequisites so that for example UNIAUD could use those new subtypes.
