# Highly Nonlinear Approximations for Sparse Signal Representation

# A simple scheme for compressing sparse approximation of melodic music.

The paper below produces the proof of concept of a simple scheme for compressing sparse approximation of melodic music. The merit of the scheme is illustated by comparison with the MP3 compression format, on a set of melodic clips executed by solo instruments and orchestras.
