Summary: abx tool doesn't work on PowerPC/Macs/big-endian
Initial Comment:
The abx tool doesn't run on some big-endian hardware,
including an Apple iBook with a PowerPC CPU.
Test run:
[...usage banner...]
Reading castanets_insane.mp3 ...Only 1 or 2 channels
are supported, not 512
Reading castanets_xing128.mp3 ...Only 1 or 2 channels
are supported, not 512
2*SOUND_PCM_WRITE_BITS ioctl failed: Invalid argument
unable to set sample size: Invalid argument
32 bit SNDCTL_DSP_SETFMT ioctl failed: Invalid argument
unable to set data format: Invalid argument
44100 Hz*0.000 sec
SNDCTL_DSP_SETFRAGMENT ioctl failed: Invalid argument
Comment:
This is probably a complex issue, as shown by the
diverse error messages. But LAME's misc/abx is
currently the only decent double blind test tool for
Linux/*NIX users. I hope somebody can fix it, or maybe
port it to libao, libmad, libsndfile and similar
portable libraries.

Changing this to a bug instead of a Feature Request. The program not
working (not even on little-endian machines) is a bug.

etatoby,
It wasn't working for me even on x86-64 (what Debian calls amd64, which is
what I use). I think that I made some progress to make it work on
little-endian machines and I would appreciate if you could test it and
report what you see.
I think that the initialization *may* (not must) have been fixed, but the
playback of the actual soundfiles is perhaps problematic (actually what you
may hear is white noise).
Please, let me know what you see. I will also perform more tests, but the
more testers that we get, the better are the chances of us getting it
right.
Regards, Rogério Brito.

Humm, since I also have an iBook, I can also take a look at this. No
guarantees, though.
I am using Linux, BTW, but the same things about endianness should affect
MacOS X. Again, No guarantees that I will actually have a fix.
Regards, Rogério Brito.
