My original message regarding submittals for nodenames.tar.gz was
missing some important information.
The nodenames.tar.gz contains asterisk sound files which are spoken in
lieu of the node number during connect and disconnect messages. For
example, without nodenames.tar.gz unpacked in
/var/lib/asterisk/sounds/rpt, you might expect to hear a message like
"Node 2000 connected to node 2010". With nodenames.tar.gz unpacked in
/var/lib/asterisk/sounds/rpt you would hear the following message
instead: "Ocean Beach Hub connected to WA6ZFT La Mesa". Note that the
node numbers are replaced with node names.
The way this works is app_rpt looks for a file whenever it has to say a
node number in the directory /var/lib/asterisk/sounds/rpt/nodenames. If
it finds a file name stem/prefix matching the node number, (e.g.
2000.ulaw) it plays the file instead of saying the node number.
Specs: These messages should be as short as possible. And encoded in 14
bit ULAW at a sample rate of 8KHz. The audio level should be normalized
to 32 percent of full level, You total file size should not exceed
50 kilobytes. Cooledit is a good suggested program to use to generate
these files.
I hope this clears up any confusion caused by the original message.
I will be taking submissions for audio files until 6/6/08.
Oddest thing, I can't seem to find a single program for Mac OS X that does 14-bit ULAW. I have lots that do the SUN/NeXT ua format which I believe is the same, but only 8/16/24/32-bit, nothing in 14-bit.
What program do Linux users use to do this? I tried Audacity but it doesn't seem to even export ULAW at all.

I used sox on a linux box. sox is really cool as it can convert from virtually any coding to another. I'd be willing to bet that a version of sox could be found for the MAC OS X. I just checked, not built in but will search for it. sox is used pretty heavily in the IRLP world to convert .wav files to .ul (.ulaw) and back.
