[mythtv-users] timestretch results in chipmunk sound

[Gabe Rubin]

> am I right in thinking that?

No, it works (not currently for me) by adjusting the pitch.  When it
works right, it is very cool!

>From the official mythtv page:
"Timestretch". Though, it's really 'time-compression'. This allows the
user to adjust the playback speed slightly, but keeps the audio at the
same pitch. If you're recording a lot of shows, timestretch lets you
get through them faster. =)

>From the unofficial wiki:
New Feature (libsoundtouch)
    *      A new library has been integrated which allows the playback
speed to be increased or decreased without causing a pitch shift. This
allows folks short on time to increase the playback speed to something
like 1.5x and finish a show quicker, without feeling like they're
listening to the chipmunks.
