In this paper, we present new methods for jointly optimal scalar quantization of parameters in sinusoidal audio coding. The sinusoidal amplitudes, frequencies, and phases used to represent (the tonal component of) an audio signal are quantized such as to minimize a single-letter perceptual distortion measure under a given bit-rate constraint. The asymptotically optimal scalar quantizers are derived analytically using high-rate theory. We present different practical methods, where quantization… CONTINUE READING
