asterisk users - Nov 2003 - Prompt recording

Does anybody have useful tips on creating good quality recordings for 
use with prompts in asterisk?  I'm interested in hearing input on 
hardware (mics, dats, sound cards, etc) and software (recording 
software, dsp) as well as recording techniques.

Anything that down mixes to 8khz 8bit is fine. 8khz 8bit is the best you
are going to get on a phone line anyways, so shoot for just a tad above,
and accept the down mixing.

BTW, where you to lazy to ask google?

I used windows sound recorder to record it (with noise less background)
used sox to convert to gsm. It turned out pretty good.

Hi,
I would like to get info about integrating either Teamspeak or Ventrilo with
Asterisk.

Ventrilo and Teamspeak is free voice conferense servers/clients that are
commonly used for online voice conference over internet (IP).
Both has their own clients!

I have had some request about accessing them from telephone lines as well as
Internet and I would like to hear if anyone has done anything like it ?

- Ventrilo www.ventrilo.com
- Teamspeak www.teamspeak.org


Kind Regards
Mats

While I understand you not being interested in it, it is important to
remind as many people. You tend to speed less through a section of road
if you see the police lights on the side with cars pulled over. 

Also, I was trying to keep it brief so as to not be too annoying.

For conferencing Teamspeak is great, no doubt. Being able to join TSS 
conferences from * would be a great thing indeed. Maybe this is a 
suggestion worth to post on the TSS forum as well?

Cheers, Philipp

For the dutch prompts we use a condensor mike (you know, the big things
they use in studios) and a Yamaha digital studio and 44.1kHz/16bit. I
like to get the original recording in as high a quality as possible,
leaves you more leeway before you get down to 8kHz/16bit. I get the
prompts as a single file with numbers spoken before each text - these
are quite handy as cue points, you can easily identify them visually in
audacity and it greatly speeds up cutting.

After cutting the prompts and saving them (audacity works nice for
that), this little script makes sure that all the voice prompts have
more-or-less the same (maximum) volume:

#!/bin/sh
tmpfile=/tmp/rescale$$.wav
for i in *.wav; do 
  scale=$(sox $i /tmp/foo.wav stat -v 2>&1)
  if [ $scale != "1.000" ]; then
    echo -n "Rescale $i..."
    cp $i $tmpfile
    sox $tmpfile -v $scale $i
    echo
  fi
done

Hth,

Cees

I usually find recording from a PC gives you a sound that is too
"full"?...

...but I haven't read the stuff at voip-info (yet, gimme 5)

I use our phones to record the prompts... I created an extension that
records the prompt, plays it back, and when it sounds right I copy the
test.gsm to asterisk/sounds

<snip>

exten => 8,1,Wait(1)
exten => 8,2,Record(/tmp/test:gsm)
exten => 8,3,Wait(1)
exten => 8,4,Playback(/tmp/test)
exten => 8,5,Hangup

</snip>

Hmmm, you mean a SIP or H.323 interface to TeamSpeak/Ventrilo ?
