Abstract
A method, system and product are provided for selectively modifying an encoded audio signal. The method includes receiving the encoded audio signal, the encoded audio signal having a first frequency bandwidth, and identifying a delivery point for the encoded audio signal, the delivery point having a second frequency bandwidth. The method also includes selecting a plurality of subbands from the first frequency bandwidth based on the second frequency bandwidth, and modifying the encoded audio signal based on the plurality of subbands selected. The system includes control logic for performing the method. The product includes a storage medium having computer readable programmed instructions for performing the method.
Claims20
A method for selectively modifying an encoded audio signal, the method comprising:
- receiving the encoded audio signal, the encoded audio signal having a first frequency bandwidth;
- identifying a delivery point for the encoded audio signal, the delivery point having a second frequency bandwidth;
- selecting a plurality of subbands from the first frequency bandwidth based on the second frequency bandwidth;
- and
- modifying the encoded audio signal based on the plurality of subbands selected.
A system for selectively modifying an encoded audio signal, the system comprising:
- a receiver for receiving the encoded audio signal, the encoded audio signal having a first frequency bandwidth;
- means for identifying a delivery point for the encoded audio signal, the delivery point having a second frequency bandwidth;
- and
- control logic operative to select a plurality of subbands from the first frequency bandwidth based on the second frequency bandwidth, and modify the encoded audio signal based on the plurality of subbands selected.
A product for selectively modifying an encoded audio signal, the product comprising a storage medium having computer readable programmed instructions recorded thereon, the instructions operative to select a plurality of subbands from a first frequency bandwidth associated with the encoded audio signal based on a second frequency bandwidth associated with a delivery point, and modify the encoded audio signal based on the plurality of subbands selected.
