If you have files of 8-bit samples for Phil Karn's "play" program,
you can convert them using the program "sndcnv". Sndcnv scales the
samples, and deletes every other sample. (The files Phil distributed
were mostly oversampled by 2.)
For example, starting with the file "circuits", which is 8-bit samples
@ 22ks/s, we convert to "circuits.2" which is 16-bit samples @ 11ks/s
sndcnv circuits. circuits.2
nkfsa -sfcircuits.2 -sr11000
it is not necessary to specify the sample rate when you feed NKFSA from
a file, but it does make the frequency annotation correct.
