Abstract
Technique and mechanism for processing polyphonic audio signals. Processing includes filtering the audio signals to generate a set of narrow band signals, estimating an instantaneous magnitude and frequency associated with the narrow band signals and driving a bank of sinusoidal oscillators based on the instantaneous magnitude and frequency to create an output audio signal.
