Abstract
Methods and systems of processing audio data with a multi-stage audio front end model is provided. A one-dimensional audio waveform is received as input and processed using a multi-stage audio frontend model to convert the one-dimensional waveform into a two-dimensional matrix representing features of the audio waveform. The multi-stage learnable audio frontend model is configured to apply a first filterbank to the audio waveform to generate a first time-frequency representation of the audio waveform; apply a first decimation filter to the audio waveform to generate a first decimated audio input; apply a second filterbank to the first decimated audio input to generate a second time-frequency representation of the audio waveform; and stack the first time-frequency representation and the second time-frequency representation together to generate the two-dimensional matrix.
