wav2txt - BSU program converts WAV audio to ASCII text (C-Language Version)
wav2txt [ -h | infile | n1 | nlast ]
Basic Seismic Utilities (BSU) program that converts a WAV audio file format to an ASCII text format output. If only 1 channel, output is 3 columns (sample number, time, data ). If stereo (2 channels), the output is 4 columns (sample number, time, ch1_data, ch2_data). This code was developed to read data recorded on a sound card (an AM modulated tone in the audio range). The modulation signal extends down to 0 Hz for a lower limit. Upper limit would be dependent on the carrier tone frequency. C-Language Version.
