Acid files verses timestretched files ?

[luxgud]

What determines how good timestretching and pitchshifting is using an ** Acid file ? **

I can appreciate that an application like Ableton Live can do this very well using a wave file because it uses a good algorithm, but with an Acid file is the quality also at the mercy of the algorithm ?

Thanks.

Yes.

An ACIDized .wav file simply contains meta-data that tells the program where the main transients are, what the key is, the tempo, etc. The actual application that loads that file will determine the sound quality according to how well it's time-stretching routines acts upon the extra ACID specific data in the wave file.

Thanks, I suspected as much but it's nice to have it confirmed.
