- Title: "Who Said That?" - Accurate Estimation of Audio Signal Parameters
- Description: Speech and music signals are often modeled frame-by-frame as a sum of harmonically related sinusoids. However, short-term Fourier transforms of such signals often reveal that the peaks of the harmonics are not at exact integer multiples of the fundamental frequency, a phenomenon called inharmonicity. An important problem in audio signal processing is to find accurate estimates of the signal parameters despite such modeling mismatches. In this regard, we will be looking into the possibility of using quasi-harmonic models to develop general iterative and adaptive estimates of sinusoidal signal parameters that can also be used for audio signal processing.
