Since several years I use a solution which should be finally ported to
the recent SoX version as a separate program but I lack time to do it.
My current solution is a patch to run SoX full screen, interactively,
with ability to modify speed and volume and jump through the recording
easily with simple key-strokes. Other interactive modifications could be
added easily in the code. Not many formats are seekable in this version,
I use WAV.


How the window with my interactive SoX looks like:
