Subject: Re: Audible distortion/clipping
From: Chris Holt (amiga2k_at_cox.net)
Date: 2003-01-21


From the manual:
Auto Volume (Recorder only)
Auto volume is a feature that automaticly lowers the volume on loud parts,
and then slowly restores the volume to the previous level during N seconds.
That N time is configurable here.

This would not help me with overly quiet tracks.
