Claim 12:
13. A system, comprising:
a memory configured to store a machine learning (ML) model; and
a processor, which is configured to:
obtain a plurality of initial audio signals, which have first durations in a first range of durations and which are labeled with respective levels of distortion;
slice the initial audio signals into slices having second durations in a second range of durations, shorter than the first durations, so as to produce a set of training audio signals;
train the ML model to estimate the levels of the distortion based on the training audio signals, by (i) converting the training audio signals into respective images and (ii) training the ML model to estimate the levels of the distortion based on the images;
receive an input audio signal having a duration in the second range of durations; and
estimate a level of the distortion in the input audio signal by applying the trained ML model to the input audio signal.
