Systems and methods for modifying an audio signal using custom psychoacoustic models

An audio processing device comprising:

• a processor;
• and
• a memory storing instructions which when executed by the processor causes the processor to:
• determine one or more parameters of the processing function based on an optimization of perceptually relevant information for the audio signal;
• parameterize the processing function with the one or more parameters;
• and
• process the audio signal by applying the processing function, wherein calculation of the perceptually relevant information for the audio signal is based on a hearing profile comprising masking thresholds and hearing thresholds.

A non-transitory computer readable storage medium storing instructions which when executed by a processor of an audio processing device, causes the processor to:

• determine one or more parameters of the processing function based on an optimization of perceptually relevant information for the audio signal;
• parameterize the processing function with the one or more parameters;
• and
• process the audio signal by applying the processing function, wherein calculation of the perceptually relevant information for the audio signal is based on a hearing profile comprising masking thresholds and hearing thresholds.
