setting bitdepth

Still playing with the trial version.  How do I set the bitdepth for a track?

All internal processing is 32-bit float, all the time.  Therefore...

Oh wait here, you mean for RECORDING a track.  That's set in the audio hardware setup and F4 Settings/Multitrack/Defaults now, isn't it?  This is one of my gripes with AA2, because I can no longer record a mix of 16- or 32-bit tracks.  It's all LOCKED to the default, unless ya'll know something I don't.

Yeah, I'm talking about recording and yeah, I want to be able to record one track in 24-bit and two other tracks in 16-bit, all simultaneously.  In the pdf Help file, it says that bitdepth can be set in track properties, but in the trial version of 2.0 I'm working with I'm not given that option when I arm a track to record.  I suspect that the option doesn't exist, because the screenshot in the pdf file is of version 1.5, not 2.0.  It might be that the trial version lacks certain features that the full registered version has.  Dunno.

Why would you need to record separate tracks at different bit depths? If the sources are a different bit depth then Audition will record them all as 32 bit but with the unused bits set to 0. All your subsequent processing will be in 32 bit anyway.

My initial aim was to limit the size of files.  I also wanted to see if Audition could do it.  (Apparently it can't.)  More recently still, I've been recording three tracks simultaneously at 32 bit and 88200 KHz just to see how my machine handles it.  The file sizes are relatively huge, but I want to see if I can detect a smoothness to the higher sample rates that isn't there at CD 16-bit/44.1 KHz.  I bet I won't be able to tell the difference.  But that's another issue.

I highly doubt you'll hear any difference with higher sample rates.  And I'm sure you won't hear any difference recording at 16 or 32bitFP.  Processing quality, however, will likely be another story...
