Replay gain is a means of taking disparate pieces of music, mastered at
different levels, and making them come out of your system at the same
volume level. The goal is to alleviate or eliminate your need to turn
the volume up and down on a per song ( or other frequent ) basis.

Replay gain allows you to get your volume at a comfortable level and
enjoy your music. Unfortunately this comfortable level, when faced with
digital noise at max volume, is still enough to blow speakers.

As digital data is present on the server (for the most part) before
being sent to the SB, what would be useful is a scanner that looks for
digital noise in the input stream. This would help the overall signal
chain quite a bit.

However, what is really needed is what radio stations use which is
essentially a real-time mastering engine. This includes compression,
equalization, gating, peak limiting, etc. This is the only way to get
quality sound from a wide variety of music. It requires a lot of grunt
to run such a mastering engine. If the SB system were a bit more open,
the sound streams could be bussed into existing PC-based digital
mastering tools and then out to the SB for on-location D/A. Maybe that
will happen one day ;-)
