Subject:Please somebody reply! Posted by: Bison_Flower Date:8/22/2002 8:05:20 PM Most music doesn't change tempo abruptly, but gradual tempo changes add a lot of color. Unfortunately I can't seem to gradually change tempo in SF 6.0. We have pith shift that can be done gradually, but I see nothing for time stretching. Does anyone know if there is a way to smoothly change from eg.: 108 BPM to 80 BPM (and vice versa) over 8 measures? This would help immensely in crossfading. Please note - I've read the matching tempo FAQ - I DO NOT want to match tempos, I want to CHANGE tempos gradually. The best I've found is to time stretch 110% repeatedly over and over again on progressively smaller segments of music. This puts terrible distortion into the music and sounds awefull! Ideas?
Subject:RE: Please somebody reply! Reply by: vanblah Date:8/23/2002 9:43:36 AM I have found that changing the "tempo" of a music sound file any more than the most minute amounts is not desirable. The problem is that you aren't working with the music itself, you are working with a recording of the music, which includes all of the reverbs, instrument decays etc. These would be slowed down inclusively, thus the distortion and awful sounding music. Not to mention the fact that the further from the original you move, the more "silence" has to be filled. Even if you gradually shift the tempo, the outcome is the same, you are still deviating from the original. Speeding up the tempo is a little better, but not much. Voice-only (non-singing) works a little better, as do dry percussive sounds, but again only in small amounts. Maybe someone out there has a little more experience with it and could get you some better results. Anyone?
