These tests require a file of speech, recorded at 16 bits/sample, 8000 samples/second. The file should be called "pre_ima_adpcm.wav". The tests compress this file, decompress it, and store the results in another file called "post_ima_adpcm.wav". Listening tests may be used to evaluate the degradation in quality caused by the compression.
