We study the application of parametric piecewise modeling (PPM), a novel coding technique, for audio coding. PPM is based on either the polynomial, Bezier or Chebyshev parametric representation. It has already been proposed for curve and surface modeling use in computer graphics and has been recently proposed for source and channel coding. PPM speeds up the process of generating graphics, has increased compression capability and to a certain extent can predict missing parts of the signal. Results show that high compression of audio signals is achieved using PPM. Further we can see that error correction, to a certain extent, can be achieved using PPM due to its prediction capabilities
