Abstract
A system includes a memory and processor. The memory is configured to store a machine learning (ML) model that is trained to estimate values of frequencies added (FA) in sparse input signals that have been derived from respective input audio signals, the sparse input signals being indicative of one or more FA in the corresponding input audio signals. The processor is configured to (i) receive an input audio signal, (ii) derive from the input audio signal a sparse input signal indicative of the FA in the input audio signal, and (iii) estimate the values of the FA in the input audio signal by applying the trained ML model to the sparse input signal.
