Abstract
Disclosed herein are systems, methods, and non-transitory computer-readable storage media for automatically analyzing, modifying, and mixing a plurality of audio signals. The modification of the audio signals takes place to avoid spectral collisions which occur when more than one signal simultaneously occupies one or more of the same frequency bands. The modifications mask out some signals to allow others to exist unaffected. Also disclosed herein is a method for displaying the identified spectral collisions superimposed on graphical waveform representations of the analyzed signals.
Claims41
A method comprising:
- identifying a first band occupied by a first and a second signal;
- and
- applying a first dynamic masking algorithm to the second signal by attenuating the second signal in the first frequency band.
A system for mixing audio signals, the system comprising:
- a processor;
- a module configured to control the processor identify a first band occupied a first and second signal;
- and
- a module configured to control the processor to apply a first dynamic masking algorithm to the second signal by attenuating the second signal in the first frequency band.
A non-transitory computer-readable storage medium storing instructions which, when executed by a computing device, cause the computing device to mix a plurality of audio signals into a single signal, the instructions comprising:
- identifying a first band occupied by a first and a second signal;
- and
- applying a first dynamic masking algorithm to the second signal by attenuating the second signal in the first frequency band.
A method comprising:
- generating a first dynamic mask that is associated with the time-frequency instances where the first and second signals have amplitudes greater than a threshold value;
- and
- applying the first dynamic mask to the second signal, whereby the amplitude of the second signal is attenuated at the time-frequency instances indicated by the mask.
A method of displaying a plurality of electronic audio signals on a user interface, the method comprising:
- receiving a first and a second signal;
- displaying waveform images representing the first and second signals;
- determining the time-frequency instances where the first and second signals have amplitudes greater than a threshold value;
- and
- indicating on the displayed waveforms the time-frequency instances where both the first and second signals have amplitudes greater than a threshold value.
