emit, jqlaw re codec embedding in data files:
The decompression of a digital file is a mathematical operation; most of the perceptual audio codecs use some form of calculus-based algorithms (fast Fourier transforms, etc) for compression. These algorithms provide the math instructions used by the DSP to expand the compressed data. As long as the DSP is programmable and has a core set of resident instructions for locating and loading these algorithms, it should be able to load them from various sources, including a set location within the music file or files. Hope this helps.
