The xcorrSound tool compares sound waves using cross correlation and finds the best overlap. The package contains several tools.
* overlap-analysis (earlier xcorrSound) is a tool to find the overlap between two audio files. It outputs best sample number and second and value of match.
* sound-match is a tool to find all occurrences of a shorter wav within a larger wav
* waveform-compare (earlier migration-qa) is a tool that splits two audio files into equal sized blocks (default 5 seconds) and outputs the correlation for each block (a_i,b_i), if a and b was the input
* sound_index is a tool to build an index in which sound-match can find all occurrences of a shorter wav (still in development phase)
