Thanks Rounik. I should have been more precise in the wording of my question. When bouncing a project in Logic, there are two basic options of Realtime or Offline. The latter is obviously much faster (probably 20 times or so), which raised my concern about the fidelity of that process. You are correct that Waveburner only has one option for bouncing, which is offline. In this case, I'm a little less concerned because the bounce is only capturing a single stereo track, whereas my bounces in Logic may incorporate dozens of tracks. When burning to CD, you can select the burn rate, from 4X to 32 X. Again, if there is no risk of data errors, I'm wondering why there is a speed option. I'll probably burn my masters at 4X to be on the safe side. Thanks again.
