Method and device for equalization of an audio signal distorted by ambient noise
The method involves detecting a spectrum of the audio signal over a defined frequency range, detecting a spectrum of the noise signal over the frequency range, determining frequency intervals in the frequency range whose local maxima are associated with the noise signal, correcting the signal based...

| Zusammenfassung: | The method involves detecting a spectrum of the audio signal over a defined frequency range, detecting a spectrum of the noise signal over the frequency range, determining frequency intervals in the frequency range whose local maxima are associated with the noise signal, correcting the signal based on the determined frequency interval for local maxima to increase signal comprehensibility and reproducing the corrected signal. An independent claim is also included for an arrangement for distortion correction of an audio signal with an external noise signal. |
