My experience is that CoolEdit 2000 takes forever to resample from
48kHz to 44.1kHz, and that I use the ResampAudio program out of
the AFsp suite of programs which does just as good a job (if not better)
and is a lot faster due to the lack of GUI getting in the way.


There's a good reason for that, you don't get something for nothing.


Not really, the process is handled somewhat inefficiently in CoolEdit.
To start with when you finish you still have to save the file, and
it does an undo backup before you start.

You can disable undo in Cool Edit.

ResampAudio reads the file
in and spits another copy out, and immediate overhead saving.

The algorithms employed by ResampAudio are the same as used by
CoolEdit 2000, and you have much more control of the parameters if
you want as well.


The bit about "same algorithms" is a bold statement! Reading the link
you gave:
http://www.tsp.ece.mcgill.ca/MMSP/Do...sampAudio.html
I don't know if what you say is true, because the methods used within
Cool Edit are not published - are they?

FWIW no one seems to have picked up on my first reply
http://groups.google.com/groups?dq=&...g.goog le.com

....where I suggested SSRC (
http://www.doom9.org/index.html?/software2.htm scroll down) which
really is equally as good as Cool Edit, but free.

Cheers,
David.

Well we don't know for sure, but this is a well understood area of DSP.
There is therefore unlikely to be any black magic going on in CoolEdit.
The algorithms in ResampAudio are high quality algorithms, and judging
by the limited amount twiddling you can do with the CoolEdit algorithms
they are at least very similar.
