1. An apparatus comprising:

  • a volume adjuster to apply a plurality of equalization adjustments to an audio signal to generate an equalized audio signal, the plurality of equalization adjustments output from a neural network in response to an input feature set including an average volume representation of the audio signal;

    a thresholding controller to;

    detect an irregularity in a frequency representation of the audio signal after application of the plurality of equalization adjustments, the irregularity corresponding to a change in volume between adjacent frequency values exceeding a threshold; and

    adjust a volume at a first frequency value of the adjacent frequency values to reduce the irregularity;

    an equalization (EQ) curve generator to generate an EQ curve to apply to the audio signal when the irregularity has been reduced; and

    a frequency to time domain converter to output the equalized audio signal in a time domain based on the EQ curve.
