hi,
i will start by saying im definately not a professional, i just downloaded a demo version of broadcast and im having trouble getting it to work. i plan on using it for amatuer/cb radio station i have and am jus trying it out with a computer mic. the problem is that i have no idea how to set the i/o configuration.
can anyone help?
thanks,

September 1, 2010 at 8:17 pm #11324JesseGMemberThat’s not true at all. I know plenty of ham guys using it, and it kicks butt pretty good against the Orbans, CRL, Omnia, etc out there on the dial today.
As for CB radio, I’m not sure if Breakaway has the right low-pass filtering to perfectly match a CB channel, but I should think it would work well if Breakaway can somehow be calibrated along with the transmitter side being used. Breakaway on CB would be insane, you would sound like the king of the road. 😉
I have about 400 watts ERP on my CB in my car, with a tuned full-wave (coiled) antenna/cable system. The radio… custom rebuilt by an old guy that used to live around here before he died. Regularly blowing away guys that claim over 1,000 watts, and I sound super clean on air. Adding Breakaway would be hilarious.
But yeah, there’s plenty of ham guys using Breakaway in comparison to the boxes from the other guys – Orban being a popular brand for ham too.

Deadkey (nice nick), you’ll want to set the input to be your microphone, and the output to be your speakers/headphones just to listen at first. Headphones is recommended. Then you’ll want to do two things.
- in settings, go from "Phase Linear" to "Low Latency" which is 146 samples of latency within the core. way less than Phase Linear.
- in I/O Config, goto advanced and optimize the buffer/latency
How you optimize the buffers is to
- try switching both input and output soundcards to the KS Interface, which is short for Kernel Streaming. you will get the lowest latency when using Kernel Streaming, or ofc ASIO. the advantage of Kernel Streaming is you can have any input and output card unlike ASIO which has to input/output from/to the same card. ASIO’s advantage is even lower latency. The rest of this list is for non-ASIO only.
- make sure there’s no crackle on the output by using Test in Test tone mode, increase output buffer size until any skipping/glitching stops.
- switch test over to Pass-through, and listen to the audio coming from the input. if it skips/glitches, increase input buffer size until it stops.
- with input audio still playing for testing… start reducing the output Buffer Size one at a time to see how low it can go. try increasing the Buffer Count to see if you can decrease the Buffer Size even more. The total size of latency is the Buffer Size multiplied by the Buffer Count (not including the audio processing itself), so make sure you don’t end up increasing the total latency more just to get the Buffer Size lower. it’s the total latency that counts.
- after that’s stable, do the same thing with the input Buffer Size and Count.
- click Finish button, and see how low the total latency is from your mic to the headphones.
How does that work? 8)

way cheaper and better than the ham stuff out there for interfacing stuff. It handle up to 3,000 watts, although you’ll probably just be running a line level interface through it 😛That and an XLR adapter for your mic input, and it should save you a lot of headaches down the road.
September 3, 2010 at 8:48 pm #11326yorkie98ParticipantHi,
Sorry if my initial comment appeared to mislead you. I think here in the UK, what we describe as HAM radio is different from other countries.
I the UK HAM or as it is more commonly known here "Amateur Radio", is basically a slightly upper class licenensed version of CB, whereas CB is unlicensed and almost completely deserted, with the exception of a few die-hards and truck drivers.
In the UK, the broadcasting of music on CB or HAM radio is prohibited, as is the use of processing/compression on voice transmissions. Despite being prohibited it is fairly commonplace and not policed or enforced.September 4, 2010 at 3:09 pm #11327Joop KrauthausenMemberJust a question,
processing CB radio ? is this the 27 Mhz ? those transceivers have a very narrow bandwidth .. is it worth the effort to process the microphone ?
And HAM .. is it like local radio ? or people who test stuff all day 🙂 … you know ,amateur radio.
In the Netherlands you can not broadcast between 87.5 -108.0 not even with a amateur licence..
Is the HAM thing licence free in the united states ?Can anyone listen in without special receiving equipment ? (not like a normal radio).
just.. curious..
Greetz !
