| Abstract | In this paper, we present a novel decomposition for sinusoidal audio coding using an amplitude modulation of sinusoids via a linear combinations of arbitrary basis vectors. The proposed method, which incorporate a perceptual distortion measure, is based on the relaxation of a non-linear least squares minimization, and offers benefits in the modeling of transients in audio signals. Further, rate-distortion curves indicate that using a sinusoidal audio coder with the proposed decomposition will be preferable to one without it. This result is also confirmed by listening tests that indicate that, for a given bitrate, significant improvements can be gained over a typical sinusoidal coder. |
