SoundTouch is an extension (based on the SoundTouch library used in Audacity) to change pitch, tempo and PlaybackRate of a wav file.
Supported audio data format : 32bit floating point PCM mono/stereo
Capable of real-time audio stream processing:
- input/output latency max. ~ 100 ms.
- Processing 44.1kHz/16bit stereo sound in realtime requires a 133 Mhz Intel Pentium processor or better.

Wow, you've been busy. This is really awesome!
Thanks conceptgame!
Awesome! Is there some sort of license for the library that I should be aware of, by the way?Originally Posted by conceptgame
The SoundTouch library is released under the GNU Lesser General Public License (LGPL) v2.1.

Well that's lame, who on earth has that good processors these days
Nice work!
BTW, if you're interested I could show you how to add support for MMF's inbuilt audio samples. My Sound Player extension can dynamically add and play any MMF sample. It's quite easy to add that functionality, it's just that that part of the SDK is undocumented.
Lol, no idea.Well that's lame, who on earth has that good processors these days
I just copied the functionality from the SoundTouch website.
That is for sure really interesting.BTW, if you're interested I could show you how to add support for MMF's inbuilt audio samples. My Sound Player extension can dynamically add and play any MMF sample. It's quite easy to add that functionality, it's just that that part of the SDK is undocumented.
As I was looking for sound documentation in MMF, I did not find anything really useful. Then, I looked at your OpenAl extension but I did not find something related to built-in sound in MMF.
I would be glad to learn about it.
Here's some code from the extension:

The most convoluted function is PlaySnd:
the first 2 parameters are of course those MMF-related ones. id is the sound ID (use FindSoundFromName etc.), mainWin is also MMF-related, and the next one is the sound playback flags (constants that start with PS_). For example, PS_LOOP can be specified to loop the sound, and then the next parameter is the number of loops (otherwise it can be left 0 I think). Channel is the channel index from 1-32.
PlaySnd(rhPtr->rh4.rh4Mv->mvSndMgr, rhPtr->rhIdAppli, id, rhPtr->rhHMainWin, PS_LOOP|rdPtr->defFlags, loop, channel);
That's about it, if you know this the rest should be clear, I think!
Ok, it seems easy and obvious once explained. Thanks Looki.
That is a pity that it was not documented.
I wanted to release this extension in the Released extension part of the forum but it seems that I do not own the rights to do so.
Therefore I post the released version here: http://clicks-en-stock.concept-game....SoundTouch.zip
Awesome! Thanks for the release!
