examining what i had recorded further, it seems the recorded takes will start out of sync and clipping sets them back on the correct time
now when i go to record the audio doesn't line up correctly with what hear during the recording versus the playback, it seems delayed a few seconds
I experienced to same problem too.
Can you let me know what your system specs are and some information about the session into which you were recording? Were there several tracks of other audio? When you adjusted the buffer size, how did the audio quality improve? Also, if you can send a short example of the problem to firstname.lastname@example.org I'd like to take a closer look.
it seems like it may be an issue with iTunes being open simultaneously. i've noticed if i shut down iTunes the problem seems to go away.

and also the highest buffer rate throws of the timing of the recorded audio so it is not on the correct time but rather delayed a few seconds. this seems to be a software issue completely and nothing on my end
next time the problem occurs i'll send you a sample, yes i was recording multiple tracks but usually the problem occurs right away so i don't get further than three tracks recorded before noticing it
okay, so i emailed the entire session... the timing issue isn't a noticeable here because it seems to be correcting it but the clipping is

I'm not entirely clear on what you mean by "clipping" which usually refers to a waveform that often peaks 'above' 0dB and therefore sounds distorted and crunchy. From your description, it sounds like the issue is more likely dropouts where the audio is coming in faster than it can be written to disk (for various reasons) and therefore is missing small snippets here and there.
In either case, I would always recommend closing any unnecessary applications when recording - especially audio applications such as iTunes. If the audio is indeed "clipping," then that implies the incoming signal is too loud and this would need to be adjusted either in the OS X Audio/MIDI Setup, your mixer device feeding the signal to your audio card, or the original audio source. If it is, rather, dropping out and missing small bits of audio, there are a few common methods to prevent this: first, increase the size of your I/O Buffer under Preferences > Audio Hardware. Unless your recording while monitoring existing tracks, I would recommend bumping this up to 1024, or in incremental steps from your current setting until you no longer experience the problem. If this makes no difference, ensure that no applications that might otherwise be heavily accessing your hard drive are running while you record. This might include download managers or torrent clients, drive cleaners or archiving utilities. Even antivirus software can take a heavy toll on performance while writing data to disk.
I'll add that since the public beta was released, significant improvements have been made to the performance while recording in multitrack and I'd suspect many of these issues will be minimized or no longer an issue. I would recommend verifying with the 30-day trial edition when Audition is released.
yeah i was unsure about the terminology. you were correct about the audio cutting out. The trouble with increasing the i/o buffer is the audio then is thrown out of sync with the tempo of the beat i'm recording on. thank you for your insight so far.
is there any word on when the final version will be released? i'm about to install windows with bootcamp and run audition that way because of these issues but if its coming out soon i can wait...
