Hi,
How can I get info from an ogg file that tells me things like sample
rate, bit-depth and other information? sndfile-info doesn't seem to know
about ogg files. (A surprise to me...)
Thanks in advance,
Mark

What about:
file filename.ogg
from the shell?

Gustavo,
Hi. I didn't know about file. Thanks! I don't think it's telling me
too much, or I'm not sure how to read the results. It does tell me
sample rate, which is a step forward:
bash-2.05b$ file gmc2.ogg
gmc2.ogg: Ogg data, Vorbis audio, stereo, 44100 Hz, ~128031 bps, created
by: Xiphophorus libVorbis I 20011231 (RC3)
bash-2.05b$ file examplesustain.ogg
examplesustain.ogg: Ogg data, Vorbis audio, stereo, 44100 Hz, >256000
~224000 bps, created by: Xiph.Org libVorbis I 20020717 (1.0)
bash-2.05b$
I have an ongoing problem with the OSS part of Alsa. I noticed this
evening that the file examplesustain.ogg doesn't have the problem, while
pretty much every other ogg or wave file I play does. I was thinking
that one of these might be 16-bit, or 24-bit, etc., or something like
that, but I don't see that here.
I looked at the man page, but nothing jumped out at me.
Thanks very much though.

Yes.. As a Unix user I use the command file too much!...
But, as someone else posted, ogginfo does a better job in this case.

vorbis-tools come with their own utility
called ogginfo which does exactly
that.
Thanks in advance,

Check out ogginfo(1) - it should've come with vorbis-tools and tells you
all that good stuff:

My suspicion is that the first one, which pops, is generated from 240bit

I don't know if what happens is that the header of a sound file has been
treated as sound and it is generating the noise.
You can cut it out with rezound, for example...

No, sorry. I wasn't clear enough. The files are fine. I can play them on
other systems, or with other sound cards, and I don't get any problem.
The only time the noise problem shows up is with my high end $500 sound
card, and only when using Alsa OSS emulation. It's perfectly fine on
Alsa audio.
For instance, I can play wave/jazz_seq1.wav using alsaplayer and I get
no noise, but xmms playing the same file through OSS has trouble.
The thing I was after tonight was that the examplesustain.ogg file is
the first one I've found that plays in multiple OSS apps and doesn't
make the noise. I wanted to try and understand why it doesn't make the
sound.
Sorry for not being more clear.
Thanks for your help.

IIUC theres no "bitwidth" inside oggs, its just a representation of the
shape of the input signal, so the bitdepth of the source shouldn't have a
significant effect on the kind of data stored. I may be totaly wrong here
though.
Is there a DC offset which the cheap card is eating?

A DC offset is an interesting idea. How would I test for that?
Thanks,
