Re: [Harp-L] An open-source audio time-stretching tool for Windows

Ken, I don't know this particular product but have a similar one that  
can pitch shift, or tempo shift. I use it all the time to find what  
key is best for me to sing a tune in, or to slow down and loop some  
lick I'm trying to steal. The software I use is excellent, inexpensive  
and runs on Windows and Mac - it is called The Amazing Slowdowner by  
Roni Music - http://www.ronimusic.com/

Cheers

From the blurb: "BestPractice is a musician's practice tool, to slow  
down or speed up music, either from an MP3 file or directly from a CD.  
Ordinarily the sound is distorted when slowed down our sped up - you  
get the effect like when playing a 33 rpm record on 45 rpm speed  
(remember the Chipmunks?). BestPractice tries to correct this, so you  
can slow down and speed up music, while keeping the original pitch. It  
is also possible to change the pitch of the music without affecting  
its tempo. Play along with for instance Eb tuned guitars without  
retuning your own, or slow down that high-speed guitar solo on a CD  
that you like to learn."

I haven't tried this program, no idea if it's any good. -K
