[FFmpeg-user] pitch corecting audio?

[James Heliker]

Hello All -

I've got content that was originally 23.976 sped up to 25 for european 
distribution. I need to shift / correct the audio pitch back down to 
normal without affecting the timing. Is there a filter for FFmpeg that 
can accomplish this task? I've been reading through the online 
documentation for things like atempo and asetrate but they don't seem to 
do what I need.

Thanks much!
