Re: [ubuntu-uk] Radio Software
Dear All, Thanks for the wide range of useful answers. As Rob has mentioned it is a legal requirement by the radio regulator in the U.K , to have 42 days of audio available to hand over at a moments notice. Many options to look over but (and I'm sure you've heard this line before...) I'd prefer something with a GUI as I'm a relative newbie with Ubuntu (although plenty of experience with OSX and Windows) and it's usefull to visually montior the audio input levels. Darklog looks like it has an excellent front end to retrieve the data. The cron job solution could do the trick. I'm a right in thinking alas mixer has a GUI? Again thanks for the answers. - Chris 2008/8/21 Rob Beard <[EMAIL PROTECTED]> > Robert McWilliam wrote: > > On Thu, Aug 21, 2008 at 12:50:22PM +0100, Chris Weaver wrote: > >> Our legal logger - this is simply a application that records an mp3 > >> file from a live input creating a new file every 24 hours.

They tend to get a bit funny if you can't give them the audio they ask for and they can ask for any audio from any time in the day or night. Sometimes it can get so bad that the station gets fined. When I worked at GCap we had our own in house logging software which kept copies on the local station site on the dedicated logging machine and also send copies back to the data centre for storage/retrieval with a disaster recovery option being a standard 4 hr VHS tape on long play.

Darklog will do the job: http://www.radio.warwick.ac.uk/software/logging.htm It's a pig to compile and get working though. I believe it is actually possible to do this with Darkice as it can output to a file. This might help... http://groups.drupal.org/node/8475 I've been trying to get something similar working for a hospital radio station (albeit it's not legal logging) but not actually had much time to get a solution working. Another option if you have a fast enough machine is to setup a cron job to record using something like alsa'a arecord and give it a duration of 86400 seconds (24 hours) and get it to run say at 12am every night, and then have another cron job which compresses the existing audio into OGG or MP3 format (from experience when I worked at GCap we used to send audio on CD in WMA format to Ofcom so presumably they'd probably want either audio CDs or MP3/WAV format audio).

Obviously you'd want a better script than this, but just as sound idea. This could then be served via samba (network drive), and/or served as a http directory listing. Hope this is some pointer in the right direction :) Kind Regards, Dave Walker -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/

There is no shortage of sound recording utilities for Linux. Are you after something that can do scheduled recordings? I don't know of any apps that support that out of the box [1] but there are a couple of different apps that support recording from the command line (ttyrec, arecord and the gstreamer tools for making your own pipeline come to mind) and a few different ways of scheduling commands, so building a scheduled recording system is possible (I can help if you want). The "legal" part of "legal recorder" has me a bit worried though: is this system something needed by law? If so, exactly what is required? What kind of reliability do you need? With a custom FOSS solution you don't have a vendor to shift the blame on to if it all breaks horribly Robert [1] A quick google came up with Pydar, but I haven't used it so can't say how well (or even if) it works. http://www.redfelineninja.dsl.pipex.com/software/pydar.html Robert McWilliam [EMAIL PROTECTED]www.ormiret.com He who laughs last thinks slowest! -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/

Hello Chris, CW> Our legal logger - this is simply a application that > records an mp3 file from a live input creating a new > file every 24 hours. Currently we use > http://www.cooolsoft.com/mp3rec.htm but searching the > linux-audio pages I'm unable to find a similar > application. Any ideas? I would favour a modular approach: use some fairly ordinary recording software to capture each programme as a .wav file (I prefer .au, but .wav seems more common these days) and then while the next programme is airing, the previous can be compressed into MP3 and Ogg/Vorbis, perhaps for posting on your Web site. This could be automated fairly easily. I'm assuming you want to do this for live shows. If you also have pre-recorded shows, you probably already get those in digital (hopefully uncompressed) format. - Andy Ball -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/
[ubuntu-uk] Radio Software
(apologies forgot the subject line) Dear All, I'm not sure if this is the right place to post but... I work at a small community-radio station in London called Resonance104.4FM. I'm slowly reducing our dependence on Windows and moving to Ubuntu for our editing and day to day needs. I'm stuck on application at the moment. Our legal logger - this is simply a application that records an mp3 file from a live input creating a new file every 24 hours. Currently we use http://www.cooolsoft.com/mp3rec.htm but searching the linux-audio pages I'm unable to find a similar application. Any ideas? cheers, - Chris Weaver -- Chris Weaver Production Manager Resonance104.4FM resonancefm.com +44 (0)207 407 1210 -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/
