Claims
- 1. A method for synthesizing a subband encoded audio signal having a plurality of frequency subbands, each subband having a scale factor and sample data associated therewith, the method comprising:selecting a first subband encoded audio signal, the first signal having a plurality of frequency subbands, each subband having a scale factor and sample data associated therewith; selecting a second subband encoded audio signal, the second signal having a plurality of frequency subbands, each subband having a scale factor and sample data associated therewith; and synthesizing an encoded audio signal directly from the first and second subband encoded audio signals, the synthesized encoded audio signal having the scale factors of the first subband encoded audio signal and the sample data of the second subband encoded audio signal.
- 2. The method of claim 1 wherein the first encoded audio signal comprises a perceptually encoded audio signal.
- 3. The method of claim 1 wherein the first encoded audio signal comprises a voice recording.
- 4. A system for synthesizing a subband encoded audio signal having a plurality of frequency subbands, each subband having a scale factor and sample data associated therewith, the system comprising:a controller for selecting a first subbband encoded audio signal, the first signal having a plurality of frequency subbands, each subband having a scale factor and sample data associated therewith, and a second subband encoded audio signal, the second signal having a plurality of frequency subbands, each subband having a scale factor and sample data associated therewith; and control logic operative to synthesize an encoded audio signal directly from the first and second subband encoded audio signals, the synthesized encoded audio signal having the scale factors of the first subband encoded audio signal and the sample data of the second subband encoded audio signal.
- 5. The method of claim 4 wherein the first and encoded audio signal comprises a perceptually encoded audio signal.
- 6. The system of claim 4 wherein the first encoded audio signal comprises a voice recording.
- 7. A product for synthesizing a subband encoded audio signal having a plurality of frequency subbands, each subband having a scale factor and sample data associated therewith, the product comprising:a storage medium; and computer readable instructions recorded on the storage medium, the instructions operative to select a first subband encoded audio signal, the first signal having a plurality of frequency subbands, each subband having a scale factor and sample data associated therewith, select a second subband encoded audio signal, the second signal having a plurality of frequency subbands, each subband having a scale factor and sample data associated therewith, and to synthesize an encoded audio signal directly from the first and second subband encoded audio signals, the synthesized encoded audio signal having the scale factors of the first subband encoded audio signal and the sample data of the second subband encoded audio signal.
- 8. The product of claim 7 wherein the first and second encoded audio signals comprise first and second perceptually encoded audio signals.
- 9. The product of claim 8 wherein the first perceptually encoded audio signal comprises a voice recording.
