waveform [N/A]
output:
$cmnd attaches RIFF header(s) to input raw file(s).
The outfile has an extention ".wav", e.g.,
sample.m15 ---> sample.m15.wav
If the infile has an extention ".raw",
the extention is removed, e.g.,
sample.m15.raw ---> sample.m15.wav
The outfile is stored in the same directory
as the infile.'
However, once a destination directory is specified,
all wav files are stored in that directory.
