  • Audio compression
    Publication number: 20050231396
    Abstract: A method of scalable audio compression includes bitplane coding of frequency-domain transform coefficients, where newly-significant coefficient locations within the current bitplane are identified using runlength codes. Reordering coefficients prior to bitplane coding such that same-frequency coefficients are clustered together has the effect of increasing coding efficiency. The invention is applicable to both full-bandwidth and layered bitplane coding.
