Local AM/FM modulations estimation: application to audio sinusoidal modeling and blind source separation
Audio signal analysis/synthesis results
The results are expressed in terms of RQF (measured in dB between reference analyzed signal and the reconstruction through the estimated parameters).
Audio blind source separation results
The results are expressed in terms of RQF, SIR, SDR, SAR computed through BssEval
