A Codebook-based Cascade Coder for Embedded Lossless Audio Coding

Document Thumbnail

Embedded lossless audio coding embeds a perceptual audio coding bitstream within a lossless audio coding bitstream. Such an approach provides access to both a lossy and lossless version of the audio signal within the one coding scheme. Previously, a lossless embedded audio coder based on the Advanced Audio Coding (AAC) approach and utilizing both backward Linear Predictive Coding (LPC) and cascade coding was proposed. This paper further investigates the adaptation of cascade coding to lossless audio compression using a novel codebook based approach. The codebook is trained using LPC residual signals obtained from the decorrelation stage of the embedded coder. Results show that the overall lossless compression performance of cascade coding closely follows Rice coding.
