Systems and methods for analyzing components of audio tracks

Abstract

A method is described comprising receiving a stem signal and an audio mix signal, wherein the audio mix signal comprises information of the stem signal. The method includes applying a first transform to the stem signal to provide a first stem spectrum, applying a second transform to the stem signal to provide a second stem spectrum, generating a plurality of mix signals using the audio mix signal, applying a first transform to each mix signal of the plurality of mix signals to provide a corresponding first mix signal spectrum, applying a second transform to each mix signal of the plurality of mix signals to provide a corresponding second mix signal spectrum, and using information of the first stem spectrum, the second stem spectrum, a first mix signal spectrum, or a second mix signal spectrum to detect the information of the stem signal in the audio mix signal.

I claim: 
     
         1 . A method comprising,
 receiving a stem signal and an audio mix signal, wherein the audio mix signal comprises information of the stem signal;   applying a first transform to the stem signal to provide a first stem spectrum;   applying a second transform to the stem signal to provide a second stem spectrum;   generating a plurality of mix signals using the audio mix signal;   applying a first transform to each mix signal of the plurality of mix signals to provide a corresponding first mix signal spectrum;   applying a second transform to each mix signal of the plurality of mix signals to provide a corresponding second mix signal spectrum.
