Abstract
An apparatus for processing CELP-based frames includes a first module for extracting a CELP parameter from a source codec, a second module coupled to the first module adapted to interpolate between a CELP parameter of the source codec and a destination codec, the CELP parameter being selected from a group consisting of a frame size, a subframe size, and a sampling rate, a third module coupled to the second module adapted to map the CELP parameter from the source codec to a CELP parameter of the destination codec, a fourth module coupled to the third module adapted to construct a destination output CELP frame based upon the CELP parameter from the destination codec, and a controller coupled the first, second, third and fourth modules, adapted to oversee an operation of the modules, adapted to receive instructions from an external application, and adapted to provide status information to the external application.
