align-audio: Find relative time displacement of two recordings of the same music
Say, you have a video with some background music and a clean recording of the background music. You want to know exact displacement of the background music. This program should find it.
align-audio orig.wav video.wav
The program actually performs a simple correlation.
The program can handle sources of different sample rates if the sample rates are integers.
You can specify the precision of the displacement using the --rate option,
which must be a positive integer:
align-audio --rate 1000 orig.wav video.wav
For reading of audio files, libsox is used
and thus you can use all audio formats supported by SoX.
