Alias-free, multiresolution sinusoidal modeling for polyphonic, wideband audio
We describe an improved method of generating more accurate sinusoidal parameters (amplitude, frequency, phase) from a wideband polyphonic audio source in a multiresolution, non-aliased fashion. This significantly improves upon previous work of sinusoidal modeling that assumes a single-pitched monophonic source, such as speech or an individual musical instrument. In addition to a more general analysis, we can now perform high-quality transformations such as time-stretching and pitch-shifting on polyphonic audio with ease.
