I sometimes depend on logic's bounce feature for final mixes so I was horrified that people thought there was sound degradation. Because of Logic's klugy features, flaky bugs and e-magic's egregious support and attitude towards its customers, I often think we're using a toy where a professional tool is needed. But since I depend on Logic's feature set, I decided I'd better get my own answers on the bounce issue. I got some time in my studio yesterday and performed the following test: On my LAP 3.7.2 (I'm still waiting for the #@!$#%&*# manual to upgrade to 4) with Pro Tools mix hardware I digitally recorded tracks from a CD into a session. I bounced the "mix" which was just the recorded audio from the CD onto a split stereo file. Adding the stereo file back to the arrange window, I was surprised to hear a phase cancellation (not total silence) that made the sound very thin. Needless to say, inverting phase didn't help. After trying the same test in Pro Tools with perfect results (inverted phase had total cancellation) I thought maybe there's just an offset in Logic. Sure enough I went into the Sample Edit window, moved the bounced audio by 6 samples and voila- the tracks canceled. Conclusions: 1. The bounce feature itself does not alter audio (objectively) 2. Bounced tracks can be delayed (6 samples in my case) which can lead to phasing effects in this test Now can we get back to more productive topics like importuning e-magic for the manual?
