Hi,
I was wondering if anyone can help me out with this one. I’m trying to use Breakaway Broadcast to process an TV channel running on Scala Infochannel 3. Scala mixes the Line-In from the soundcard, with the Wave audio from the movie files we start every 2 hours. For this mix action (Line-In 100% -> 0%, Wave 0% -> 100%) Scala uses the default Windows soundcard. Which is breakaway. But Breakaway doesn’t have a Line-In, so the audio from the Line-In keeps playing when the movie is started. Unfortunately I can’t force Scala to use the real soundcard to mix.
Anybody here that has any bright idea’s to fix this? 🙂Thanks!
Hi Peter!
Scala! I haven’t heard that name since Amiga days 🙂.
Because Scala actually relies on the sound card mixer to do its audio routing, I believe the only way to handle this is with a second sound card in the machine, connecting the output of the main card (used by scala) to the second card, used by Breakaway.
Also, I recommend Breakaway Live, which is much lower latency than Broadcast, so it’s fast enough for video use.

This is the same for CARMEN TV (local product in The Netherlands). You’ll need 2 soundcards. We did some testing with it early this year. You have to connect the line out for the "main" soundcard to the line in of the 2nd soundcard and let breakaway run on the 2nd soundcard. And hook up the line out of the 2nd soundcard to the modulator.
But i don’t recommend using breakaway on the same machine as your playout! We did also, and the machine couldnt keep up, video (cpu intensive) started hicking. A dedicated computer for breakaway live is advised.
Wow, really? I wouldn’t have guessed that Breakaway Live would use enough CPU to make a difference, unless the computer was already on the edge. Breakaway Broadcast, on the other hand, is very cpu intensive.

Does Breakaway conform to Dialnorm standards? If so, I’ll suggest it at the TV network that I do contract work for. It’s actually a US-based national network, and they have been having huge debates among the engineers about what audio level is acceptable for network/local inserts. I am guessing that a Breakaway deployment at the affiliate level is more appropriate, since doing it at the network level would only be useful while the affiliates are in network programming.
Thoughts, Leif?

Adam, dialnorm is outside of the scope of Breakaway.
I can however recommend Linear Acoustic’s products! Our products solve exactly the kind of projects the network is facing, and many more. We’ve been building DTV-related audio products since 2002, and our products are already in use at many national networks in the US.
Best,
///LeifThanks Leif…I know they have the LA boxes on the network side, but for some reason, they don’t have them affiliate-side. And being that we’re all processing geeks, we all know that processing should be the last thing in the chain.
