Abstract
Format converters and methods of performing data format conversion are provided. The format converters may convert compressed data into a different compressed format that is compatible with the Bluetooth transmission standard. The format converter may decompose the compressed data into frequency domain data streams of different frequency sub-bands. The format converter may transform each data stream of frequency domain information from a first encoding scheme to a second encoding scheme, and may then quantize the transformed data steams based on bit allocation information for each sub-band. The format converters may also include a bit allocation component which computes the bit allocation information for each sub-band based on an unfiltered version of the compressed data.
