Abstract:
A coder and decoder, and methods therein, are provided for coding and decoding of spectral peak positions in audio coding. According to a first aspect, an audio signal segment coding method is provided for coding of spectral peak positions. The method comprises determining which one out of two lossless spectral peak position coding schemes that requires the least number of bits to code the spectral peak positions of an audio signal segment; and selecting the spectral peak position coding scheme that requires the least number of bits to code the spectral peak positions of the audio signal segment. A first one of the two lossless spectral peak position coding schemes is suitable for periodic or semi-periodic spectral peak position distributions; and a second one of two lossless spectral peak position coding schemes is suitable for sparse spectral peak position distributions.

Claim (Index 6):
An audio coder for coding spectral peak positions of an audio signal segment, the coder being configured to:\n determine which one out of two lossless spectral peak position coding schemes that requires the least number of bits to code the spectral peak positions of an audio signal segment, wherein a first one of the two lossless spectral peak position coding schemes is suitable for periodic or semi-periodic spectral peak position distributions and a second one of the two lossless spectral peak position coding schemes is suitable for sparse spectral peak position distributions and comprises:\n dividing a bit vector representing the spectral peak positions into consecutive equal size bit groups; \n OR-ing the bits in each bit group to form a group bit vector; \n compressing non-zero bit groups by exploiting constraints in the minimum allowed distance between two consecutive peaks; and \n providing the group bit vector and the compressed non-zero bit groups as an output of the second one of the two lossless spectral peak position coding schemes; \n selecting the spectral peak position coding scheme that requires the least number of bits to code the spectral peak positions of the audio signal segment; and communicating an indication of the selected spectral peak position coding scheme to a radio transmitter circuit to transmit the indication of the selected spectral peak position coding scheme toward a decoder to enable the decoder to decode coded spectral peak positions of the audio signal segment based on the indication of the selected spectral peak position coding scheme.
