ACID: Warble/Flutter in track playback -ACID Product Family

Subject:ACID: Warble/Flutter in track playback Posted by: Alphonso Date:5/1/2003 8:29:49 AM I have pasted an otherwise fine vocal loop into ACID and when it plays back in the mix it "warbles" or flutters, as if it's out of phase or something with the rest of the recording. There's nothing wrong with the file. I've also has this problem when I've recorded a guitar track directly into ACID, and I can't for the life of me figure it out. Anybody else has this problem? FYI, I have 1 gig of DRAM and every other computer factoid super-charged, so it can't be a technical glitch on the machine. It's a software issue. Thanks for your help.

I'll try the bouncing trick tonight, but it sure seems like a design flaw to take something I've recorded into ACID and destroy it on playback. I wonder why there would be a needless next step to ensure the track wasn't ruined?

(You could use the Chopper too.) In any case, when you bounce down and create a Loop, you're essentially not changing the way the recorded take sounds. As I've said, the project's tempo and key is taken into account. It's that info that's added as a chunk of data to the file (ACIDizing). The only way it could sound different at that point is if you were to change key and/or tempo. Otherwise, it'll sound the same as it did before the bounce. You might to check some things: -Was the vocal loop itself ACIDized? A lot of WAV's available on the 'Net are not. If not, ACID will generally assign a tempo based upon the length of the file. ACID will not assign key info. Generally, you'll want to assign this data yourself, either by using the bouncing method I mentioned before or use Sound Forge's (excellent) ACID loop creation tools. -If you're using a Sound Blaster Audigy, take note that the Audigy does 16-bit/48 kHz internally. That means if you have a sample that's really 44.1 kHz, it'll get resampled in real time by the Audigy, potentially causing problems. Try matching the Audigy's internal bit-depth and sample rate by changing your overall project to 16-bit/48 kHz. Record at those settings as well. -Update your soundcard's drivers if possible. Try also reinstalling your existing drivers if newer drivers aren't available. HTH, Iacobus
