Developer/QA Backing
Bill Koz Steve

Motivation/Use Cases

 * Compare the spectra of different recordings of the same performance and EQ one to sound the same as the other.
 * Compare the spectra of recordings of different performances recorded at different times or places and EQ them to sound similar. This would be for collecting these recordings on a CD release or compilation.
 * Possibly useful in audio analysis e.g. environmental noise.
 * Forum threads [here] and [here].
