[mythtv] Audio Glitch Detection

Hi all,

Has any work ever been done regarding the ability to mute audio glitches
during playback?  Occasionally problems with OTA reception will cause
part of the stream to be missing which produces very annoying high
pitched "pop" and "squeak" sounds.  I know that some of the more
upmarket STBs are able to detect when this is happening and apply a low
pass filter or simply mute the audio.  Does anyone know of:

* any freely available documentation which outline algorithms for fixing
audio glitches


* any other OSS which already implements it (Kaffeine, perhaps?) that
MythTV can borrow code from?

Lastly, would it make more sense for this functionality to be added to
MythTV as it records or as it plays back?
