Which algorithm/library/program is used for sample rate conversion by
cdrecord in Linux? Other programs? I assume there is a library to
perform this function, which is used by most utilities, xmms, amarok,
cdrecord, audacity, etc. Is there any easy way to find this out?
I have just done a simple test burning some sound recorded as a WAV file
at 48,000 Hz to a CD (at 44,100 Hz of course), and think I have noticed
a small reduction in quality.
Thanks - jon

Thanks. A little checking of the audacity sources and K3B shows that
they do use libsamplerate, which appears to be the best available. Also
thanks to Mr. de Castro Lopo.

No sure about cdrecord.
Other programs?
Ardour, Sweep, Audacity (I think), ecasound and any other program
that cares about quality sample rate conversion uses the Rabbit:

ldd <program name>
If you see libsamplerate.so.0 there the <program name> uses the Rabbit.
If cdrecord doesn't use the Rabbit, then you can use the command line
sample rate converter (sndfile-resample) included in the Rabbit source
code. In Debian/Ubuntu there us a precompiled binary in the
samplerate-programs package.
