time stretching

A non-loop-content question, but not about guitars either. Reply using

Has anyone used software to time-stretch samples? I'd like to be able to 
stretch very fast and complex natural sounds (birdsongs, etc), but the 
resulting samples should not lose their sound quality. I've heard good 
quality 
time-stretched samples - so I know it can be done - but I don't know how. 
I was 
not happy at all with the programs I've tried so far. The resulting 
samples 
(same pitch, but double duration) sounded like shit. They were all 
modulated as 
if treated with a low-pitch ringmodulator. Speeding the samples up to 1/2 
duration sounded even worse.

Ideas anyone?
