We are new users who have had to press breakaway one into service sonoer than we expected after a hardware failure of our main Omnia processor- breakaway is now running our main FM output after hopefully setting it up nearly correctly !
In the absence of a manual (or none that I can find) I have a couple of questions I’m afraid
We are using a MOTU Ultralite with buffer set at 256 (is that low enough ) presumably I use this in ASIO mode and nothing else enabled in Breakaway ?
I want a LOW latency output on a separate out of the sound card if possible to feed the studio with a processed signal for presenters similar to the fm processed signal
Im a little confused about how to achieve this …a screenshot also attached of what i currently have
What is the COMMON output…. I had assumed that was the separate low latency path which was then routable to any output of sound card but I dont think I'm correct
should I be using SPEAKER output ?sorry for the basic questions , but I really cant find documentation on this anywhere
appreciate any help

Hello,
Good choice on the audio interface!
From the screen shot, it looks like you got it right. "Common" is the section is in, but it's actually named the "monitor output". By selecting low latency as you did, you are indeed getting the low latency "fake air" audio through whichever audio channels you assigned as the common monitor output in config.
Whether 256 is low enough depends on the sample rate. If 192k then it's definitely low enough – just 1.33 milliseconds. Multiply that by the (in, process, out), add the algorithm delay (4ms maybe) and any other audio interface I/o delay, and you're still under 10ms.
Best,
Leif ClaessonThanks Leif and great to hear from you personally !..
Interesting…as a recording engineer I actually went for 44.1khz by force of habit …should I up this then to 192khz to reduce latency?
I found a big issue with the MOTU and W10 …Im having great trouble seeing the audio setup of the Motu- it seems its common on w10 for it not to run if ANYTHING is using audio in the background..
Ive killed everything I can think of but still it wont run…any ideas on that? It only ran once , after a new install of the motu drivers but never since LOL !Breakaway is a v promising program indeed and sounding great ……one question
with the studio Low Latency monitoring , is that somehow hearing the full processing but with less latency than the main Fm processed signal, and if so , by how much…cant seem to find any info on that ..thanks again !

You mentioned FM — if you're running 44.1 that means you're using an external stereo generator.. I would strongly urge you to try the internal stereo generator in BaOne, which will require running the MPX output at 176.4k or 192k. It won't reduce latency (in fact the Breakaway Core always runs at 44.1 or 48.0k, and if the i/o is at a higher rate it will up and down-sample automatically.), but it will greatly reduce on-air audio quality.
The MOTU Ultralite is DC coupled, so it's perfect for MPX, but you will of course need to run it at 176.4 or 192.0 to take advantage of that.
The low latency processing very similar but uses IIR filters instead of FIR (so it's not phase linear — phase linearity incurs a lot of delay because the natural behavior (with any analog style filter) is that bass takes longer through the crossovers than treble does, thus you must delay the treble to compensate, so that all frequencies pass with the same group delay, which is the definition of phase linear). Also the low latency processing does not use a clipper or pre-emphasis, it uses a look-ahead limiter instead. So, it won't sound exactly like the air, but it works great for the studio.

Thanks again Leif
Yes regarding the FM bit…we MAY have bought the wrong option…our processor is studio based and merely sends a processed signal TO the transmitter via a BARIX box ……… its basically replacing our blown up Omnia..:-)
Should I be using the HD rather than full FM option at this end, as obviously we dont need the FM specific stuff like MPX/stereo generator at this end….thats handled at the transmitter ……thanks for the info on LL monitoring…make sense !

I did…kind of ….
BUT heres what you have to do..
stop breakaway
UNINSTALL motu audio ..do NOT reboot PC
immediately RE install Motu audioadjust any latency settings etc in audio control panel…
reboot and restart breakaway if not running as a serviceyou have to do this EVERY time to make any adjustments to MOTU audio Control panel
hope that helps!
