Abstract: A multi-channel linear predictive analysis-by-synthesis signal encoding method detects (S 26 , S 27 ) inter-channel correlation and select one of several possible encoding modes (S 24, S 29, S 30 ) based on the detected correlation.

Abstract: 12. A MULTI-CODEBOOK FIXED BITRATE CELP SIGNAL BLOCK ENCODER/DECODER INCLUDES A CODEBOOK SELECTOR (22) FOR SELECTING, FOR EACH SIGNAL BLOCK, A CORRESPONDING CODEBOOK IDENTIFICATION IN ACCORDANCE WITH A DETERMINISTIC SELECTION PROCEDURE THAT IS INDEPENDENT OF SIGNAL TYPE. INCLUDED ARE ALSO MEANS FOR ENCODING/DECODING EACH SIGNAL BLOCK BY USING A CODEBOOK HAVING THE SELECTED CODEBOOK IDENTIFICATION.(FIG. 2)

Abstract: Perceptually relevant non-speech information can be preserved during encoding of an audio signal by determining whether the audio signal includes such information. If so, a speech/noise classification of the audio signal is overriden to prevent misclassification of the audio signal as noise.

Abstract: A multi-codebook fixed bitrate CELP signal block encoder/decoder includes a codebook selector ( 22 ) for selecting, for each signal block, a corresponding codebook identification in accordance with a deterministic selection procedure that is independent of signal type. Included are also means for encoding/decoding each signal block by using a codebook having the selected codebook identification.

Abstract: In producing an approximation of an original speech signal from encoded information about the original speech signal, current parameters (EnPar(i)) associated with a current segment of the original speech signal are determined from the encoded information. Reproduction of a noise component of the original speech signal is improved by using at least one of the current parameters and corresponding previous parameters respectively associated with previous segments of the original speech signal (31, 37, 39) to produce a modified parameter (EnPar(i) mod ). The modified parameter is then used (25, 40) to produce an approximation of the current segment of the original speech signal.
