Audio encoding and low latency, comprise alternating predictive coding and transform coding

摘要

1. A method of encoding a digital audio signal, comprising the steps of: encoding (E601) predyschuschy digital signal samples by frame predictive coding, encoding (E603) the current frame of digital signal samples by transform coding, characterized in that the first part of the current frame is coded (E602) by predictive coding, predictive coding with respect Acronym previous frame by reusing at least one parameter etc. dskazatelnogo encoding the previous frame, and only the coding parameters are not re-used parts of said first current freyma.2. A method according to claim 1, wherein the condensed predictive coding using the predictive filter is copied from the previous frame predictive kodirovaniya.3. A method according to claim 2, wherein the predictive coding is further abbreviated using the decoded pitch value and / or the gain associated with the previous frame predictive kodirovaniya.4. A method according to claim 1, wherein some of the parameters of predictive coding used for predictive encoding Acronym differentially quantized with respect to the previous frame decoded predictive parameters kodirovaniya.5. A method according to claim 1, further comprising the step of obtaining the reconstructed signals obtained by encoding and local decoding, and predictive transform said first part of the current frame, and by combining (E604) of said recov
