AIFF vs MP3 Timing
When exporting/bouncing/converting an MP3 (for refrence) out of
ProTools (or digital performer) is there any timing shift in tempo from the original source. I am doing some cyber sessions and it seems as if sometimes its hit or miss, just the slightest change will screw up a session. |

I am doing some cyber sessions and it seems as if sometimes its hit or miss, just the slightest change will screw up a session. Hmm.. Don't think so? I'm flying mp3s and aiffs in and out of different tracks and arrangements all the time and I've never noticed any differences in timing. A low quality mp3 might sound slower because of the duller sound, but it should be running at the exact same tempo. However, on older versions of Logic I've had some funny occurences where the waveform at the very beginning, ie the beginning of the first bar, appeared to look a little different after bouncing. Might have had something to do with the editing not being sample-accurate, not sure, I didn't find this to be a problem really, still sounded ok, but it was a bit weird. One particular third party plug-in in Logic is running with latency on my old G4, which is bloody annoying. It's got delay compensation settings but those don't always work as they should. Sometimes it's in sync, sometimes not, but I think I'm running the computer beyond its capacity, so I have to freeze or bounce tracks before doing the final mixdown. If you have a newer and more powerful computer that should not happen the way it does on mine. Not sure how the buffering works, but sometimes the buffers appear to be full of junk and slowing things down, leading to latency. I wish I understood this better so I could set the preferences differently or clear out some of the useless data. Resetting the software usually sorts this out, but I don't like the unpredictability of it, accurate timing is pretty important huh? |

I have had situations when working on other producers projects where the tracks I was flying back into the session were problematic, but I did not generate the mp3's so I really couldnt tell where the problem was coming from. So I guess its safe. Thank Again |
