Abstract: In implementations of music enhancement systems, a computing device implements an enhancement system to receive input data describing a recorded acoustic waveform of a musical instrument. The recorded acoustic waveform is represented as an input mel spectrogram. The enhancement system generates an enhanced mel spectrogram by processing the input mel spectrogram using a first machine learning model trained on a first type of training data to generate enhanced mel spectrograms based on input mel spectrograms. An acoustic waveform of the musical instrument is generated by processing the enhanced mel spectrogram using a second machine learning model trained on a second type of training data to generate acoustic waveforms based on mel spectrograms. The acoustic waveform of the musical instrument does not include an acoustic artifact that is included in the recorded waveform of the musical instrument.
