Hi Dominic,
I checked out the sound files at
http://sky.prohosting.com/oparviai/soundtouch/soundstretch.html and
they sound about the same as Audacity (those I was able to load at all,
that is). Maybe they are not up to date?
Anyway, I'll have a look at the SoundStretch MacOS X binary provided on
his site and will try compiling the lib under OS X for comparison.
Thanks,
Stephan

Looks like a neat project. Keep in mind that Audacity
is just wrapping
Olli Parviainan's excellent SoundTouch library. For some more detailed
comparisons, you may want to download SoundTouch and try it out
directly;
there is a newer version than the one used in the last Audacity release
and it's possible it sounds even better. It should compile easily on
any
Linux or Mac OS X platform.

Hi Daniel,
there are quite a few solutions for musically monophonic sounds out
there that work very well indeed. It's the complete mix of
instruments that gives them a hard time, which is exactly where
ClearScale comes in: it is intended for both musically monophonic and
polyphonic material, the goal being artifact free (or at least
sonically pleasing) time and pitch changing over at least one octave,
or changing the length by a factor 2 in both directions.
Additionally, formant correction is planned which avoids the common
"munchkinization syndrome" (Mickey-Mouse-Effect) when changing the
pitch.
Cheers,
Stephan

a few Open
Source solutions around. I no experience using them
but I suspect they don't compare with the design goals
of ClearScale.
Comparing the Audacity effect with the ClearScale example at:
http://www.clearscale.org/html/results.html
yields an obvious improvement. However, I've used the Audacity
timestretching tool on less complex material with good results, such
as single vocals or drum breaks.
I'm sure the Audacity team would be interested to check out
ClearScale - I'll cc this email to Dominic.
It should be announced on the LAD list where
Stefan
can get more feedback and publicity.
I've already suggested to Stephan that he does just that, because I
agree this is something that people on the lists will be interested
in.
By the way, I just noticed that the number of subscribers to the
users
list has passed the number on the developers list for the first time
- is this a sign of something? There's a graph at:
