Scheduled Recording of Streamed Audio? 61
sborisch asks: "I have tried at least 15 different Internet Radio/Shoutcast players, looking for one with a scheduler (recorder) capability that actually works. The closest I have found are IRadio and Replay Radio, but IRadio depends on the Windows scheduler, and isn't the least bit reliable in my test of it. Replay seems to want to send everything through your sound card, and hence makes it impossible to listen to something and record something else at the same time. It does have a so-called direct download option, but this doesn't seem to work either. Surely someone has found a better solution than this. Please let me know." How would you schedule a recording streaming audio from either Windows or Unix?

It would only take about five minutes (if that) to hack together a shell script that does this all automagically for you.
Re:Streaming MP3/Ogg (Score:2)
That's nasty in that you're taking an ogg/mp3 stream, decoding it, saving it decoded, then re-encoding it later. You'll lose some quality and waste lots of CPU.
Ideally you'd just save the stream that's downloaded. Sounds like that should be almost trivial to write up in perl, or you could use something like StreamRipper [sourceforge.net] rather than mplayer.

Here is how I did it.
Cron is your scheduler. man cron & crontab for more info.
mplayer will playback many streams. Give mplayer the option to output the raw audio to a file which is a named pipe. Have lame take the named pipe as input and encode to mp3.
Voila, You have a system that downloads and converts your streams straight to mp3 without any intermediate steps.

Ouch, I wish all my computers had a couple of gigs of memory. Named pipes are OK for data volumes up to a couple of hundred meg that you're going to use immediately or throw away, but if you're taking raw audio and saving it, those are potentially huge amounts of data, and if you're using a named pipe, there are data integrity issues should something happen like your cat walk across the keyboard or you lose power (like, you

That's not what he's suggesting here - he's suggesting using a named pipe as a temporary repository for your data stream, which is a bad idea, both for the strain on your memory, and the lack of integrity should your computer burp.

Yes, I know the difference between anonymous and named pipes - mostly none other than one being present in the filesystem namespace.

Anyway, be aware that you cant portably expect a pipe/fifo to hold more than PIPE_BUF AFAIK. If you know of systems that can buffer hundreds of MiB in pipes, I'd be interested to hear which.

Not necessarily. The Secure Audio Path, introduced in Windows ME and Windows XP, allows audio files to specify that they may be played only through signed audio output drivers. Microsoft signs audio drivers only if they always disable mixing Secure Audio Path audio into any cleartext digital output such as Total Recorder's .wav output. You may have to use the analog hole for some of the more restricted streams.
Why they work through your sound card (Score:3, Informative)
You can argue all you want about how legal or fair this is. But no developer has found it worthwhile to bankrupt him or herself in order to fight this kind of legal action. In any case, what's really needed is the political will to change the laws that favor IP hoarding.
The only way around this problem is to record the sounds after it's been translated by authorized software. The simple way is just to plug a patch cord into your sound card. Or you can get better fidelity by using a special sound driver that copies the audio stream to disk. But either way, you can't avoid tying up your sound card, since you have to con the authorized software into giving you a stream that's supposedly going directly to your speakers.
If you need real-time access to the recorded data, get two computers and a network.

I had a good old fashioned FM receiver which I tuned into Radio 1, it got good reception, but not quite good enough for stereo. The output of this went into a Linux PC with a rather expensive signal capture device, which I'd rescued from the trash. This was an old fashioned ISA card which had a 20 bit ADC and I could tune the frequency to almost anything I wanted. This was used by some former resident of the observatory for some scientific work, but, being scientific grade it made an excellent sound card. At least a lot better than the built in sound on my Alpha workstation.
It was installed in an old 486 DX2/66 running linux, I had to write my own driver, I had a lot of time on my hands. This was great for capturing audio, but it didn't have enough disk space for the show or enough CPU for real time mp3 encoding.
Instead I encoded it using Shorten and piped it across the network to a more modern PC which had a couple of gigs of disk space, I could get about 8-10 hours of mono audio on there.
This host would then decode the SHN data and encode it to mp3 using Fraunhofer's l3Enc - a very early command line mp3 encoder which was available for linux. I ran this in the highest quality mode available, since the data was already stored in SHN format. I don't think that there were any machines that could reliably encode realtime mp3 at that time, so this 2 stage process was needed.
Ultimately, I stored the essential mix files to a RAID array made up of 6 1Gig SCSI disks, these disks were mounted in pairs inside cases which were about the size of a PC.
I am recalling this archaic procedure as I'm backing up my entire Essential mix collection to a 300gig disk which is about the size of a book.

Recording Realaudio, WMF, OGG & MP3 Radio streams on your Linux box
I wanted to record a couple of radio shows so that I can listen to them later on my linux machine. Basically I would like to listen to a mix of realplayer, Windows Media, Ogg and MP3 streams and save them as mp3 or ogg files so I can listen to them later on my computer or iriver ogg/mp3 player.
First I tried mplayer's dumpstream command
1) mplayer -dumpfile cores -dumpstream http://wm.warnermusic.com/France/the_corrs/summer
(th
2) mplayer -vo null -vc null -ao pcm -aofile audio.wav cores
(this will convert the videofile to a wav audiofile)
3) lame audio.wav cores.mp3
(this will convert the file from wav to mp3)
However this process core dumped on realplayer recordings over 10 minutes. Also it doesn't know about ram files so you have to download them first (wget filename) and then open them to file the real link to the rm file. So I went on to look for some other tools.
Most of the tools seem to be wrappers around vsound and/or sox and lame/oggenc. Another tool I looked at is streamripper, which works for mp3 or ogg streams.
First I grabbed realcap which is a shell script front end to those tools. Downloaded, compiled and installed vsound.
Trick one - you have to ensure that realplayer is using OSS drivers
http://www.osl.iu.edu/~tveldhui/radio/
After that seemed to work I tried directly with vsound. vsound acts as a kind of virtual audio loopback cable
vsound --timing -f myfile.wav realplay http://www.radio.org/ra/show.ram
oggenc myfile.wav
xmms myfile.ogg
I also checked out the trplayer - which is a command line wrapper to realplayer. http://www.linux-speakup.org/trplayer.html.
Got the error:
