[linux-audio-user] App to sync file playback to external tick?

[Jacob]

Hi,

does anybody know an open source app to keep the play back tempo of a local
sound file in sync with an externally supplied tick (eg via MIDI clock).
The pitch shouldn't change of course. And I would be happy, if it was not
a GUI based program.

Think of merging a tempo-stable track with a live recording, where the
drummer didn't play to a metronome, so there are slight tempo changes
that should survive :-) . The click source for the sync would then be
some beat tapping on a MIDI keyboard for instance.

Thanks for any ideas,

Yours,

Jacob
