Abstract
Disclosed herein is a method of determining a plurality of inter-track auditory masking measurements between a plurality of audio tracks, the method comprising: dividing each audio track into a first set of frequency bands; and determining, for each frequency band of each audio track, an inter-track auditory masking measurement that is a measure of the masking between the frequency band of the audio track and a combination of the corresponding frequency bands of all of the other audio tracks; wherein each inter-track auditory masking measurement is determined in dependence on a psychoacoustic model.

1-25. (canceled)
A method of automatically mastering an audio track, the method comprising:
- obtaining an audio track;
- determining a harmonic signal and a percussive signal in dependence on the obtained audio track, wherein the harmonic signal comprises harmonic components of the obtained audio track and the percussive signal comprises percussive components of the obtained audio track;
- determining a residual signal that is dependent on a residual component of the obtained audio track that is not comprised by the harmonic signal and the percussive signal;
- determining, in dependence on the residual signal, the harmonic signal and/or the percussive signal, one or more inter-signal auditory masking measurements between the residual component and the harmonic components and/or the percussive components, wherein each inter-signal auditory masking measurement is determined in dependence on a psychoacoustic model;
- determining a configuration of each of one more processes for performing on the obtained audio track in dependence on the one or more inter-signal auditory masking measurements;
- and
- applying each of the one or more processes with their determined configuration to the obtained audio track to generate a processed audio track.
