[Icecast] Question

Excellent - you'll need to make sure that you have the settings that 
they use for their broadcasts so that you can take over the stream 
seamlessly with no issues. This means:

  * Audio encoder (generally mp3, HE-AAC or AAC+) Nicecast only does
    mp3; BUTT and LadioCast support both mp3 and AAC; AAC offers higher
    audio quality at a lower data rate
  * Data rate (kb/sec) (Hopefully at least 128kb/s if mp3, preferably more)
  * Sample rate (generally 44.1 kHz)
  * Word length (generally 16-bit)
  * Stereo/mono (generally stereo)

You'll want to agree handover protocols between you so that you can take 
the stream and hand it back as smoothly as possible without 
interruptions. We do this with a text instant messaging channel and 
count down to handover.

However the downside of this is that the signal would be encoded, decoded and re-encoded by the time it was broadcast. The original solution I proposed had you driving the station's servers directly, which would be preferable - they should be able to set up a DJ account for you - this is especially easy if they have a system like Centova on their Icecast system.

Alternatively, NiceCast allows you to create a local streaming server on your Mac and the station you're working with can tune in to that to receive your live audio. However NiceCast (from Rogue Amoeba) is no longer supported: you may have to ask them about it.

You could set up what is essentially a studio-transmitter link (STL), using broadcast hardware designed for the purpose. A good and relatively cheap (a few hundred $) example of gear for this is the DEVA Broadcast DB91-TX and DB91-RX which allow you to send a CD-quality uncompressed PCM stream from your location (using the TX unit) to the station (who would have the RX unit). The TX unit can also log into to an Icecast 2 (or deprecated Shoutcast 1) streaming audio server, so the TX unit is ANOTHER solution to driving the station's Icecast server directly, instead of the software solutions described earlier. We run the DB91-TX to feed from our playout system to our Icecast 2 KH servers and it works beautifully.

There is an internet radio station that uses icecast that wants to carry the audio from my broadcast live. I have no idea how to get the audio to them. I use Mac computers. Can someone help me with that.
