Title:
Coding and decryption of a spectral peak position
Document Type and Number:
Japanese Patent JP6181863
Kind Code:
B2
Abstract:
A method and an audio coder for coding spectral peak positions of an audio signal segment are provided. The method comprises determining which one out of two lossless coding schemes requires the least number of bits to code the spectral peak positions of an audio signal segment; and selecting the 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 coding schemes is suitable for periodic or semi-periodic spectral peak position distributions; and a second one of two lossless coding schemes is suitable for sparse spectral peak position distributions.
