Wavelet Scattering on the Pitch Spiral

3 Jan 2016Vincent LostanlenStéphane Mallat

We present a new representation of harmonic sounds that linearizes the dynamics of pitch and spectral envelope, while remaining stable to deformations in the time-frequency plane. It is an instance of the scattering transform, a generic operator which cascades wavelet convolutions and modulus nonlinearities... (read more)
