An Optimization Scheme for SVAC Audio Encoder

Abstract : Both audio signals and MEL-frequency cepstral coefficients are encoded in SVAC audio encoder. These two independent processing leads to structural redundancies for the encoder design. This paper proposes an optimization scheme using MEL-frequency cepstral coefficients to realize high-frequency reconstruction and removes Bandwidth Extension module of the original encoder. Simulation results prove that the new encoder has considerable improvement on structure, reconstructed high-frequency precision and coding quality.
