Hello there,
well, at first: Congratulations to Leif for this very awesome piece of software! I’m very impressed by what you’ve created…
Let me start at the beginning: we are a small non-profit team of young Radio-Enthusiasts and run a small temporary radio station every year for a few weeks in our freetime, with a licence of course! Last year, we had the luck to use a Vorsis AirAura for processing and stereo coding, but this year it may be that we couldn’t get this box for another time for some non-technical reasons (don’t get me wrong – the AirAura is a great, great box!). So maybe now it’s time for BBP!
Now I’m thinking about how BBP does match best in our existing environment:
– We use a Barix SHF-Link from the studio to the transmitter, which cannot carry an MPX-signal, so it would be the best to place BBP at the transmitter-site, right? (Same as last year with the AirAura…)
– We use a Pira.cz Hardware RDS-Encoder. This RDS-box requires the pilot-tone for syncronizing. The AirAura has offered a seperate TX2-Output, which could optionally only serve the pilot tone. Can BBP also do this?
– Which soundcard should we use? I’ve read that the Marian Trace Alpha fits best for BBP, but it has just one I/O. If we need a second out for pilot sync, this card wouldn’t fit. Any other suggestions?
– I know that Airomate could also do RDS Encoding, but is this software 100 % reliable? I’m still thinking: if we have the hardware, then we should use the hardware, because it’s more stable!
– Maybe I’m able to borrow a RME Fireface 800 for this task (this thing is a BEAST!), would it work properly with BBP?
– Another member in our team owns a licence of the BBP non-ASIO-Version for testing purposes. Should we get the ASIO-Version for our task, or does the non-ASIO-Version the job as well? (Low latency is not the point, because the Barix-STL adds already too much latency)
– How could we feed out Livestream best? I’m thinking about to use a professional Telefunken rebroadcast receiver, which we have lying around, to receive our FM-Signal, to get the same sound on the webstream. Last year, we got a seperate Vorsis VP8+ for this task to feed the stream directly over the studio-output, which was not the best idea, because the sound differed slightly from FM. We also have an Optimod PC 1101v2-Card lying around which can be used for this, but to be honest: this thing is faaaaaaaaaaaaaaaaaaaaaaaaaaaaaaar away from Breakaway! I’ve already tried it out for a longer time on my workbench, I’ve listened and tweakened and listened and… but I couldn’t really "get it out"!
– If we’ll use BBP, which preset do you recommend? Well, we’re more a public radio station, so we don’t need to "burn a hole in the dial". I’ve already listened A LOT to the BBP-Demo and my favourite is clearly "Zenith" 🙂
So, now I think you could imagine what we’re doing and where we want to go 😉
Thanks,
radiofreak
PS: Is a Processing Freakday also planned for this year? Last year, I couldn’t be there for some reason, but I would love to talk to Leif personally somewhere along the way
Best is to use BBP on transmitter site. And to use Airomate for the RDS. With the Marian trace alpha you will have DC straight output for your transmitter. If you would first feed this through the pira RDS you will loose this. Or when you want to feed it back in you need expensive sound card. So it’s better to do all in software. It is stable and high quality.
And you can use an encoder plugin within BBP for the streaming. The normal BBP version will be enough if you don’t need low latency and it will also sound better.There will be no processing freakday this year.

just use audio tx for place 2 place streaming, and then breakaway with a patsat stereo rds at the transmitter side.
child can do the dischious or how you call it
[quote author=”eldoradofm”]Stereo from BBP is much better.[/quote]
i don’t think so.
the patsat stereo rds encoders are one of the best stereo/rds encoders at the world.
breakaway stereo is a good stereo, but not mutch better then the patsat or de rds 2000 stereo/rds encodersif it measures good, there ya go.
saw Shaun White pull a 360 in warmup a couple hours ago, one of the most relaxing i’ve ever seen, made my day.
So, Breakaway is now running for a week with MPX-Out to the RME Fireface and then to an MPX-modified Rohde & Schwarz NU002. I’ve measured the MPX-output with an oszilloscope, and it’s absolutely tilt-free and has no high-frequency-cutoff! Airomate is also running with no probs and it’s stable.
But I have some problems with the Kernel-Streaming-System. The CPU-Workload is about 40 – 50 %, but sometimes it goes up to 100 % and the PC freezes for 5 … 10 seconds with a few audio-dropouts. When I use WaveOut, everything is fine… So can I leave it to WaveOut, or is KS better?
I’ve listened to my station a lot through many differend radios, from small clock-radios to big stereo systems, and everytime I was blown away!!! Leif, big compliments, you’ve nailed it!
