SoX 12.17.2 Released

I've released version 12.17.2 of SoX. Its almost a year in the making and contains tons of bugfixes and a few new effects.

Hightlights include:

o Bugfix to Polyphase effect (no longer makes files longer then they should be)
o New syth effect to create signals (see testcd.sh script for examples)
o New silence effect for triming off silence from files
o Now attempts to look at audio data to detect input format instead of just extension
o New Ogg Vorbis file handler (if you have external library installed)
o Avg effect can handle any combination of input/output channels
o trim and fade effects calculate time values correctly
o Ctrl-C stops recording again
o New experimental soxmix program to mix two sound files into one
o Bugfix in lowp filter
o AIFF files can read non-standard size data (ie 12-bit).

Please see the SoX web page for details on what changed (http://sox.sourceforge.net/).
