This is a simple brickwall audio limiter, originally used for my pet project.
Supporting both integer and floating-point audio samples, it does not
requantize incoming signal, so it can be losslessly applied to dithered audio.

I want to propose it for inclusion in GStreamer, because such a limiter is a
must-have for any audio player with replaygain support:

A -6dB hardlimiter may be also used to enchance output on some soundcard models
(a signal level above -6dB may be unsafe (introduce clipping) on consumer
hardware).

The attachement is full autoconfed source package, based on gst-template. The
plugin only needs to be updated to use GST_LICENSE, GST_PACKAGE_NAME and
GST_PACKAGE_ORIGIN in GST_PLUGIN_DEFINE macro.
