Distortion when rendering to file..... -ACID Product Family

Subject:Distortion when rendering to file..... Posted by: Starx Date:8/1/2003 7:17:38 PM I decided to do a test on acid's accuracy. I imported a small sound file into acid, I did not alter it's tempo or pitch, and I set the amplitude to unity (0dB). I then rendered that single file and compared it to the original, acid is altering the shape of my waveform. Does anyone know why this is?

Reply by: mortalengines Date:8/1/2003 10:05:51 PM I have heard from previous postings on the forum that It is true whenever you do a rendering of any track from one form or another in Acid, some degradation/distortion...whatever you want to call it can & will happen that's just the way it goes- I've also noticed when I've rendered ACD files to WAV that there is some degradation as well. This gets curbed by writing directly to CD from Soundforge.

The problem you describe sure sounds like what happens when ACID is treating a sound file as a loop, and that sound file does not contain stored tempo or beat information so ACID applies some internal defaults. ACID will timestretch the sound file to match the project, which for your accuracy testing is not what you want it to do. Longer audio files will always be treated as a One-Shot by ACID but it will assume shorter files are loops, even if they do not contain tempo or beat information.
