Abstract
Methods and apparatus for harmonic source enhancement are disclosed herein. An example apparatus includes an interface to receive a media signal. The example apparatus also includes a harmonic source enhancer to determine a magnitude spectrogram of audio corresponding to the media signal; generate a time-frequency mask based on the magnitude spectrogram; and apply the time-frequency mask to the magnitude spectrogram to enhance a harmonic source of the media signal.
Claims20
A tangible, non-transitory computer readable medium comprising instructions that, when executed, cause one or more processors to perform a set of operations comprising:
- determining an audio spectrogram corresponding to a media signal;
- based on the determined audio spectrogram, enhancing a harmonic source of the media signal;
- comparing the enhanced harmonic source media signal with one or more reference media signals to determine an audio characteristic corresponding to the enhanced harmonic source;
- and
- based on the determined audio characteristic, identifying at least one of a song, an advertisement, a show, and a video game.
A computer-implemented method comprising:
- determining an audio spectrogram corresponding to a media signal;
- based on the determined audio spectrogram, enhancing a harmonic source of the media signal;
- comparing the enhanced harmonic source media signal with one or more reference media signals to determine an audio characteristic corresponding to the enhanced harmonic source;
- and
- based on the determined audio characteristic, identifying at least one of a song, an advertisement, a show, and a video game.
