Hi Stephan,
I got this note by way of Axel Hartmann of Hartmann
Music, I'm the
Hartmann DSP guy also working for Prosoniq and as a freelance
consultant (http://www.dspdimension.com).
We have a number of members who are actively involved in DSP work, so
I'm sure they would be very interested to check out the information
on your site (if they haven't already).
On your site, I notice that you're from Karlsruhe - a number of us are
heading there for the International Linux Audio Conference at the end
of this month. Are you planning to be there?
The linuxaudio.org web site sounds and looks very
interesting,
however, due to my NDA I cannot decide on behalf of Prosoniq and
Hartmann if it is interesting or relevant for these companies to
participate.
That's fair enough. In fact quite a few of our contacts are being made
at an informal level, without interested parties necessarily becoming
members of the consortium.
The reason why I'm contacting you today is because
I have a new
project pertaining to my work at dspdimension.com that might be of
interest to linuxaudio.org as well - please find it at
http://www.clearscale.org
I'd say this is definitely of interest to our members, especially
since you are proposing to release your code under the GPL. I'd be
interested to know the advantages that your project will offer over
the existing time stretching software that I've used, such as the
tempo change effect within Audacity.
(I'll confess that although I've used this kind of software, I'm
unclear about the benefits of the various designs!)
Have you posted an announcement on the linux-audio-announce or
linux-audio-developer mailing lists?
Thanks for getting in touch!
Daniel

I think ClearScale is valuable project. I'm not aware
of anyone else that is working on a similar project.
It should be announced on the LAD list where Stefan
can get more feedback and publicity.

Hi Ron,
yes that's exactly the idea. Let me know if you have any questions,
more information on the project is always available from
http://www.clearscale.org.
Best regards,
Stephan

There are 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:

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

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 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
