[mythtv-users] OT? Timestretch playback of radio recordings

[John Pilkington]

Recordings from UK DVB-T radio stations come with a blank video stream, 
and can be played within MythTV with timestretch.  I usually strip out 
the mp2 sound to a smaller file and play this with RealPlayer, but 
AFAICT this doesn't offer timestretch, and much Googling hasn't produced 
clear suggestions.

Can anyone please recommend an mp2 player that offers speed control? 
SoX, the soundtouch library and Audacity all apparently have some 
capability but I'd like a user-friendly player as an rpm for FC5.

TIA
