Change Tempo now works! I decided to go with SoundTouch by Olli Parviainen. I used Paul Davis's floating-point patches, but I completely rewrote the build system because I didn't like either Olli's or Paul's. It's checked into lib-src now, and it works on Linux (configure --with-soundtouch, enabled by default). It should be easy enough to get it to work on Windows by creating a project file for the SoundTouch library (it doesn't need any special options; include all .cc files except for mmx_gcc.cc) and enabling the USE_SOUNDTOUCH macro in configwin.h Vaughan, are you at all interested in writing Change Pitch sometime in the next few weeks? I think you did an excellent job with both the Change Tempo and Change Speed GUIs, and it's be great if you feel like doing this last one, too. The nice bonus is that it will only take about 5 lines of code to make it functional - all you have to do is inherit from EffectSoundTouch and initialize SoundTouch with the pitch offset. And I will get around to Change Speed soon, using libsamplerate. - Dominic |

Did you do a cvs update -d to get new directories? Either do that, or specifically checkout audacity/lib-src/soundtouch. - Dominic Alexandre Prokoudine wrote: > On Wed, 26 Mar 2003 00:49:46 -0800 > Dominic Mazzoni <do...@mi...> wrote: > > >>Change Tempo now works! >> >>I decided to go with SoundTouch by Olli Parviainen.

I have a script which does updates with -d option Is it cirrect that the option --with-soundtouch has no further definition like =no, =system or =local? I'll do a clean checkout a bit later -- Alexandre Prokoudine ALT Linux Documentation Team JID: av...@al... |

Glad you did this. I haven't had time, but I couldn't have made all the
wise decisions you did about what library to use & how to do so... if
I'd been able to get anywhere at all!

I did that, and ran into a couple of snags, which I think I overcame,
but please review:
* Visual Studio doesn't automatically know to compile .cc files. I saw
that there are a bunch in libflac_cpp, with Custom Build commands
associated with them. So, I just copied those Custom Build settings for
the soundtouch files & modified the paths. Are those commands likely to
be right? I haven't done Custom Build stuff before.
* In mmx_win.cc:
* It didn't like the args to various TDStretch methods being Sample
in the declaration and short in the implementation. I changed the
implementations.
* In TDStretch::mmxSeekBestOverlapPositionStereoQuick,
short *local_refMidBuffer = pRefMidBuffer
caused a type-mismatch errror, but local_refMidBuffer wasn't
used so I removed it.
* In TDStretch::mmxOverlapStereo,
short *local_midBuffer = pMidBuffer;
caused a type-mismatch errror, but and local_midBuffer is used
so I changed the declaration to
float *local_midBuffer = pMidBuffer;
Is that okay?
Change Tempo is working for me. I did get some interesting jittery-ness
on slowing things way down (like -75%), so if that's not happening on
Linux, it may be a problem in my compile flags or what I did in
TDStretch::mmxOverlapStereo. Checked it all in.

Yessir. I'm going to be inaccessible next week, but I can probably get
the basics working before then.

If I can find time, I'd like to help or ~look over your shoulder. I feel
comfortable with wxWindows dialogs now and want to know more about the
actual audio code.

That sounds fine. > * In mmx_win.cc: Note that since we're only using SoundTouch in float mode, the mmx code should never be called at all. I'd like to leave the code in place so that it's easier to stay in sync with other versions of SoundTouch in the future, but please make sure that the mmx code is never being called. I actually think that SoundTouch is acceptably fast as it is. But if we want to try to speed it up, I actually have a fair amount of experience writing SSE code, which can do floating-point instructions in parallel just as mmx does integer. It'd be fun, but not a high priority for now. > Change Tempo is working for me.

Checked it all in. Depends a lot on the source audio. >> Vaughan, are you at all interested in writing Change Pitch >> sometime in the next few weeks?

It's really just passing lots of buffers around and remembering to flush everything in the right order. The libsamplerate code will be quite similar. - Dominic > -Vaughan > > > > > ------------------------------------------------------- > This SF.net email is sponsored by: > The Definitive IT and Networking Event.
