This report has described a simple waveform coder designed for use with stored waveform files. The use of a simple linear predictor followed by Huffman coding according to the Laplacian distribution has been found to be appropriate for the examples studied. Various techniques have been adopted to improve the efficiency resulting in real time operation on many platforms. Lossy compression is supported, both to a specified bit rate and to a specified signal to noise ratio. Most simple sample file formats are accepted resulting in a flexible tool for the workstation environment.
