Kevin Day:
|I tried recording something from fxtv to make an mpeg... i get as far as it
|trying to run mpeg_musicin, and i get:
|
| >>> Using Audio IFF sound file headers
| SmpFrqIndex: 0 is not a legal sample rate
| in "/root/whatever/myfile.aiff"
|
|I can play the aiff file in windows just fine... am I doing something wrong?
I'm not sure that I've seen this error before, but this may be a byte-order
problem. FreeBSD-versions ago, I found I had to rebuild mpeg_audio from
scratch to get the byte order so it was compatible with sox and mpeg_encode.
But to nail it down, capture a clip with "MPEG Ready" as a Target (instead
of MPEG). This'll leave you with raw capture files and a shell script with
a .sh extension). Edit the first line of the script, and change
"#!/bin/sh" to " "#!/bin/sh -x". Now, it'll print what its doing, and you
can see which command is griping.
Run the script and save off the output. E.g.:
go.sh >& OUT (csh/tcsh), or
go.sh > OUT 2>&1 (sh/ksh/bash)
See what you find.
Also, check your audio capture format. If you're not, try using Stereo 16-bit
44.1KHz.
Another thing to try: see what sox thinks of your AIFF file directly. Grab:
wget http://www.ipass.net/~dbhopper/aa8vb/dsp-recplay.tgz
compile, then play:
sox -t aiff /root/whatever/myfile.aiff -t raw -s -w -r 44100 - | \
dsp-play -r 44100 -b 16 -c 2
