Accuracy of frequency estimates using the phase vocoder

Abstract

The phase vocoder is a well-known technique for dividing an audio signal into time-varying sinusoidal components and estimating their frequencies and amplitudes. The accuracy of the frequency estimates is studied here by predicting, and then measuring experimentally, the magnitude of errors due to two factors: 1) interference between different components… (More)
