Systems and methods are provided for modifying an audio signal using custom psychoacoustic models. A user's hearing profile is first obtained. Subsequently, a multiband dynamic processor is parameterized so as to optimize the user's perceptually relevant information. The method for calculating the user's perceptually relevant information comprises first processing audio signal samples using the parameterized multiband dynamic processor and then transforming samples of the processed audio signals into the frequency domain. Next, masking and hearing thresholds are obtained from the user's hearing profile and applied to the transformed audio sample, wherein the user's perceived data is calculated. Once perceptually relevant information is optimized, the resulting parameters are transferred to a multiband dynamic processor and an output audio signal is processed.
A method for processing an audio signal based on a processing function, the processing function operating on subband signals of the audio signal, and each subband signal comprising at least one parameter of the processing function, the method comprising:
An audio processing device comprising:
A non-transitory computer readable storage medium storing instructions which when executed by a processor of an audio processing device, causes the processor to:
