Urs,
Thanks for the fast reply! I've heard of "brick wall limiters" being
used to eliminate high peaks (i.e. only allow amplitudes below some
threshold), but never for the reverse (allowing only samples above a
certain amplitude threshold).
If AUPeakLimiter is capable of such a thing, then my job just got a lot
easier. Do you know of any example code or documentation online? A
Google search doesn't turn up anything useful.
Thanks,

On the other hand, there's an AU plugin called something like "Rider"
which slowly adjusts the audio gain to a certain level... dunno if
that is what you're after...

Hi,
I searched through the list archives and could not find an answer to
this seemingly simple question. The application I'm working on needs
to perform some processing on samples from a microphone, but only if
the volume level of those samples exceeds some threshold.
Is there a way to normalize the samples passed to my IOProc so that
that every amplitude value lies within the range {-1.0, 1.0}? I get
different amplitude ranges for different microphones, even with
identical volume settings.
Am I missing something?
Thanks,
