Thanks, I will be looking at that closely and deciding if I need to switch over to the way you are doing things or adapt what you are doing to the way I am doing things on this new box. Currently I am autologging in a user and running stuff from the ~/.config/autostart directory. With qjackctl running some things on start and other things running in a screen setup that is also started in that whole chain. > > or just this link for the liquid soap config: > > http://pastebin.com/ziNEKF03 > > But the only things you need to do are: > > #Get an input stream (darkice auto grabs from line in if I remember > rightly so I'm assuming ALSA in): > liveStream = (input.alsa(id="liquidsoap"):source(1,0,0)) Actually, iirc, darkice can do jack as well. The box I am moving from was alsa based but the one it replaced was jack based. I moved to alsa years ago when I needed to run two station streams on one box and could not figure out how to make rotter log two stations on one box. I ended up using darkice to do the logging but never liked it as much as the rotter way. > > #id can be anything you want, source(1,0,0) is 1 audio, 0 video and 0 > something else I've forgotten so this would be mono > #You might have to take the stereo stream with source(2,0,0) and then > mono it with: > #liveStereo = (input.alsa(id="liquidsoap"):source(2,0,0)) > #liveMono = mean(liveStereo) This is what I am doing now as a test on the new box: #!/usr/bin/liquidsoap #message = # "The Savonet team thanks you for using liquidsoap, " ^ # "and we hope you'll enjoy it!" #set("jack.client_name","liquidsoap") set("log.file.path","/home/zloc/basic-radio.log") # We're 48k! set("frame.audio.samplerate",48000) # Grab JACK input # We don't do any fallback here; hardware silence detector is used to flip to a backup Rivendell system radio = mksafe(input.jack(id="liquidsoap")) output.icecast(%mp3(bitrate=128), host="localhost", port=8002, password="nopass", mount="zotz1.mp3", genre="Rockin", url="http://192.168.1.4:8002";, name="Rockin Rivendell 4", description="Rockin Rivendell 4", format="mp3", icy_metadata="true", radio) > > #Here do any processing to the stream you want, you could silence > detect: > emergencyFile = mksafe(single("/var/audio/emergency/silentalarm.mp3")) > #you need to obviously make and put a silentalarm.mp3 in that location > or somewhere else accessible > # Silence Detection, plays after 30 seconds of silence > liveStream = strip_blank(liveStream, length=30.0) > > #Tell it what to do when its silent (track_sensitive=true will wait for > the track to end before cutting back to the main stream): > liveStream = fallback(track_sensitive=false, [liveStream, > emergencyFile]) > > #You could have a tracklist instead of an emergency file, you can even > have a ruled tracklist that will play idents on the hour, pick random > songs from directories etc but I've never attempted that > > #Or how about compression: > liveStream = compress(ratio=3.0, attack=38.0, release=85.0, > threshold=-20.0, knee=0.5, gain=8.0, liveStream) > > #What if you need a limiter: > liveStream = limit(ratio=3.0, attack=38.0, release=85.0, > threshold=-3.0,knee=0.5, liveStream) > > #Finally send it off to icecast > output.icecast(%mp3(stereo=false, samplerate=22050, > bitrate=32),liveStream, description="Describe me", genre="Give me a > genre", url="My Website", name="Title Me", mount="what mount point to > use", host="localhost", password="my secret password", port=8014) > > Theres tons of sound processing you can do.
