and support for installs from outside the source directory.
+ o Fabien COELHO added a pan and volume effect.
+ o Fabien COELHO added a speed effect to sox (like speeding up a tape
+ machine).

+Speed up or down the sound, as a magnetic tape with a speed control.
+It affects both pitch and time. A factor of 1.0 means no change,

+2.0 doubles speed, thus time length is cut by a half and pitch
+is one octave higher.

Turn a mono sample into a stereo sample by copying
