This is what I use at several stations. This script runs on a box running
an icecast server fed with darkice instances, one for each station to be
airchecked. A copy of this script is customized for each station and
launched at the top of each hour by cron. It works very well.
At one station I am recording 384 kbps mp2 so the recordings can be used
for rebroadcast.

As we are little bit off topic..
I was looking for something similar to Rotter - easier in a sort of
way - which simply dump a mp3 streaming (no need of encoding, just
dump our webradio) into a specific folder and removes older files.
I was thinking about using command-line VLC, something like adding in
/etc/crontab an every-hour script.
Do you think it would be trustable?

Hi,
You can run multiple rotters on different jack ports. The standard set up
is something like:
ROTFORMAT="mp3" #Encoding format
ROTBITRATE=192 #Bit rate
ROTCHANNELS=2 #2 = Stereo
JACKNAME="rotter1"
ROTDELETEHOURS=2400 #Delete audio after x hours (2400 = 100 days)
ROTBUFFER=10 #Rotter internal buffer, increase if you have problems
ROTDIRSTRUCTURE="dailydir" #Organisation format man rotter for more info
LEFTJACKINPUT="system:capture_1" #Left Channel for rotter to connect to in
the format of client:port
RIGHTJACKINPUT="system:capture_2" #Right Channel for rotter
ROTAUDIODIR="/var/audio" #Directory to store audio
rotter -f $ROTFORMAT -b $ROTBITRATE -c $ROTCHANNELS -n $JACKNAME -d
$ROTDELETEHOURS -R $ROTBUFFER -L $ROTDIRSTRUCTURE -v -l $LEFTJACKINPUT -r
$RIGHTJACKINPUT $ROTAUDIODIR
Obviously if you're running two change JACKNAME, [L & R]JACKINPUT and
ROTAUDIODIR.
Out of all the random software I've ever used rotter has been the only thing
thats never crashed on me in over a year of use (liquidsoap is nearly at
2months of uptime which is my next most reliable excluding riv of course).
Hope this helps,
Wayne

Yeah, that could work.
The stations are stereo, but I only need mono for logging purposes. well
I guess I'll have to try.

If you need 2 mono stations, why don't you simply record it to a
single stereo stream? One station per channel.
I never tried, but I think you can run multiple instances of rotter in
the same jack server.

Can I run two instances of rotter at the same time connected to
different inputs in jack?
I haven't delved into jack at all either......
Thanks for the input. I may just have to try it, but don't want it
to be total waste of time if someone knows it wont work. I'd
really like to use one box for both stations.

I'm not sure about two stations.
Mono is easy use -c1
Here's my statement (I think it just uses lame parameters man lame)
rotter -a -f mp3 -d672 -j -b96 -L flat -c1 /var/archives

I know some of you use rotter to log your ouput so I was
wondering if
anyone knows if I have an audio card with multiple (stereo)
inputs can I
record the ouput of two stations simultaneously? Also does it
support
recording to a mono file to save drivespace? I can't seem to
find much
info on it, other than it uses jack to connect.
