  We introduce an audio texture synthesis algorithm based on scattering
moments. A scattering transform is computed by iteratively decomposing a signal
with complex wavelet filter banks and computing their amplitude envelop.
Scattering moments provide general representations of stationary processes
computed as expected values of scattering coefficients. They are estimated with
low variance estimators from single realizations. Audio signals having
prescribed scattering moments are synthesized with a gradient descent
algorithms. Audio synthesis examples show that scattering representation
provide good synthesis of audio textures with much fewer coefficients than the
state of the art.
