ARCO (Adaptive Resolution COdec): A Hybrid Approach to Perceptual Audio Coding

Document Thumbnail

The proposed ARCO codec pretends to be an audio coder which deals with the problem of time-frequency behavior from a joint point of view, using a signal-adapted transform for each selected subframe. The coding of the tonal parts using a perceptually driven quantization is followed by the compression of the residue using a wavelet-packets structure. The basic scheme is described including a new perceptual model, while some ideas and results concerning the adaptive behavior of the ARCO codec are presented. Apart from informal subjective tests, objective perceptual scores are presented to discuss its potentiality.
