Back onto the original topic… 🙂
"Which (internet) stations using Breakaway at the moment?"
Raw FM. We have been running BBP since the day I heard it in action. http://stream.rawfm.com.au:8000/listen.pls (MP3 160K) tune in and check it out.

Hey Leif, and running running BBP at your transmitter site, would be cheaper than a lossless hardware audio link. Especially if you have more then one transmitter location.. IE; 40 😉
Otto, man I have been down the same road and the difference is like chalk and cheese. Once you set up BBP at your transmitter and correct any tilt, tune your favourite pre-set, set your levels etc.. you will have the best sounding audio and even the loudest if you want it! 🙂 Well you will at least untill your competitors start running it 🙂 But then that’s good for the ears of the people and Leif’s wallet lol 😉 Have you seen Leif’s MPX tool software? If you haven’t you should take a look, Connected to the right receiver and set up correctly you will be able to align your levels and make the most of your FM bandwidth (don’t waste it) and to make sure your station is legal within it’s deviation limits. (if you didn’t already know 😉)
PS: Compellors lol I don’t use mine any more, Its still a classic but.

Hi Otto,
If I was you i wouldn’t run any processing before your 96 KHz PCM link as that should already sound nice and clean, and just run BBP at your transmitter. There’s no point running 2 versions of BBP in series or any processor if you can avoid it. I would run BBP Live in the studio to feed your speakers etc.. it will offer better latency then listening off air. Can your STL operate at 192KHz? then you could run BBP in the studio and feed the MPX via your STL.

A demo of Quintessence can be heard online at http://rawfm.com.au 😉 Believe me it sounds nothing like the "Dance" pre-set but more like a certain 90’s era big $$$ processor with all the style of BBP 🙂
We have over 40 sites, not all the TX sites have the Dominator 722 installed. I am in the process of purchasing some more, as well as some more Tandberg 1220’s, then running pre-emphasis on the Sat link will be a possibility…
In the mean time I have made some more tweaks and now disabled the Aphex Compellor at my local TX its now sounding more natural though not as loud but in spec, but only about 98% of the time! I have observed these overshoots on other networks too. One in particular is running Orban 2300’s but there content is news with audio around 3-5khz I think the 2300 is struggling and in some cases perhaps causing issues? Just wondering if they should have used all there old 8100’s they replaced from there other station.
We are running mono due to our ERP restrictions and the area we need/want to cover, I’m in Australia. When will Breakaway FM be available for purchase? I would like to give it a go on the uplink, as I don’t think Breakaway standard rolls off @ 15khz or does it? As much as I would like to plug your software on the station I don’t think the boss is going to like hearing the Breakaway FM demo adds on air every 10 mins or so lol 🙂

Leif,
This is a very interesting and extremely frustrating! I have spent countless hours tweaking etc.. What I should of mentioned is that the satellite link is in stereo so that only leave us with 128k audio. Today I will enquire on the possibility in reconfiguring the link into mono at 256k or even better 384k.
When you say feed the encoders digitally, Do you mean via AES/EBU or actually encoding the mpeg then streaming to the sat uplink?
Mpeg II is a very normal way of distributing broadcast audio, Is it predictable? As in, can you make your DSP know that this piece of audio is going to have problems in MPEG so Breakaway compensates somehow? or is the compression just completely random? Know what I mean?
Sam
Hi Leif,
Would you recommend Breakaway FM to enhance the satellite uplink audio (256Kbit MPEG II) that feeds our FM transmitters across the country? My problem is our FM transmissions broadcast in mono I have Aphex Dominators at the TX side that has increased the loudness while being legal, it is no chop compared the Omnia’s and Orbans in the area. I have ran various DSP software over the years before the satellite and before the FM transmitter with some limited success but your new Breakaway series sounds the best so far. Maybe you could make a pre-set to enhance the sound of MONO broadcasts?
