    Hello all,

    I would like to use Breakaway in combination with Airomate and Virtual Audio Cables (VAC).
    The setup would be like this:

    Line in Sound Card 1 => Breakaway =VAC> Airomate => Line out Sound Card 2

    Is this possible? And how will the settings be?

    Thanks in advance!

    Hi Dj Buik!

    Setup issues aside, algorithmically, it can’t be done:

    Airomate does not have a properly functioning peak-limiting back-end for FM. It has a clipper, and a low pass filter, but no matter how you set it up, you will have a lot of distortion *and* a lot of overshoots. The overshoots mean you have to turn your modulation way down, so you will not only sound distorted but also quiet.

    The one way to use Airomate is to feed it a signal that has already been perfectly peak limited (the pre-emph L/R output of an Orban processor will do this just fine, but Omnia will not), turn off the filtering and clipping of Airomate, and use it only as a stereo generator + rds generator. This works, and gives you an acceptable overshoot-free signal, but defeats the purpose — if you can afford an Orban, you might as well just use the built-in stereo generator.

    Please note that other common free solutions like Sould Solution and Sonos will have the exact same problem – they do peak clipping, but have an insane amount of overshoots, and they’re neither oversampled nor distortion cancelled.

    It’s possible that I’ll be releasing software to take care of all this, this year. I can’t guarantee it, but it’s possible. It’s written already – it’s a matter of finding the best way to sell it.

    Hi Leif,

    Thanks for the reply!

    This setup will be used for FM pirate station(s) in the Netherlands.
    These stations can not afford expensive professional equipment like the Orban or Omnia.
    So we need to find other solutions.
    Your software sounds really great and i would like to use it for these stations.

    You talk about setup issues, what are they?
    How can i direct the line-in of a soundcard to Breakaway, and use the line out of this same card?

    I hope you find a good way to distribute your software solutions.

    Hi Dj Buik!

    The one big setup issue I can think of, is that the standard version of Breakaway can only receive sound from the Breakaway Pipeline, and can only play to a real sound card, not a virtual device. So, to feed the audio to Airomate you would need two sound cards, and pipe the audio back into the computer with a cable.

    The webcaster version will not have this limitation, it will be able to use any device – real or virtual, and will be able to do what you ask.

    For the current version, if you want to process the audio from a single version, you could download the Virtual Audio Cable demo (google) and use the free Audio Repeater utility that comes with that, to feed audio from the sound card input to the Breakaway Pipeline.

    This adds latency, but it does work.

    Line in Sound Card 1 => Breakaway =VAC> Airomate => Line out Sound Card 2

    Ok there is still a Plugin called Optimax available, you can modify it in the *.ini to use no more then 95%
    The way to go is get the Line Plugin for Winamp
    LINE IN > Winamp DSP(optimax) > Wave Out ((or out_ds_ssrc))(VAC) > Airomate > LineOut
    the Optimax has a good quality, enough good quality for FM Broadcast, it does Look-Ahead Limiting.

    And we did that for years here.
    The only drawback is the Latency of the chain, but who cares, if your headphones are connected to your Mixer.

    ( Limiting the Audio Output to 0DB is braindead, always give some Headroom, at least -1.5db)

    If you need the RDS Encoding stuff, you have to use 192KHz Sample Rate
    Here the Output Plugin Link:
    http://www.geocities.co.jp/SiliconValle … s_0901.zip
    (remember to upsample to 192KHz)
    The Line Plugin:

    I never tried Airomate2, But this thing is a great RDS Hijacker.

    Fnord,

    do you mean "OctiMax"?

    I’m well familiar with that algorithm. I’m the guy that wrote it – 8 years ago. Believe me when I say, there is nothing OctiMax does that Breakaway doesn’t do better. 🙂

    There is positively no way to be competitive and sound good on FM with straight look-ahead limiting, while remaining within legal 100% modulation. The reason for this is that pre-emphasis causes huge high frequency peaks (at 75us, 15 KHz gets boosted 17dB!) and attempting to limit these with any method other than oversampled distortion-cancelled clipping will either punch a hole in the audio or cause distortion (or both).

    If you’re overmodulating (which you would be if you were anywhere near as loud as clipping-based audio processors with a look-ahead based solution) it’s not comparing apples to apples anymore — and if overmodulating is allowed, the guy with the clipper can do just like you can, and kick your stations butt again 😉.

    Whatever if the Signal has overshots or not , he’s a Pirate.
    The Problem today is the Radio Stations try to be as loud as they can, they don’t care about the quality.
    So if a Pirate doesn’t sound that good, who cares?, those peoples who listen this Stations, don’t really cares about.

    I Remember to Radio 24, A Half-Pirate ( because he was licensed in Italy), They used 1MW EIRP, with 128EL quad field, to send 180KM or so trough the Alps, but the Audio Quality was awesome, even if you compare to todays digital processors.
    The sound are very warm.
    So if you can, get some analogue equipment, its affordable.

    The loudness war in radio has been going on for almost 40 years, it’s certainly nothing new 😉.

    The problem with overmodulation (and peaks) is not just purely regulatory. Apart from causing the receiver to lose lock (replacing S-sounds with white noise as if the station isn’t tuned in right), it can cause interference to neighbouring stations. Whether the authorities care about pirate broadcasters or not, they certainly will care if the licensed stations are calling in to complain about interference!

    Also, if audio quality is not important — why do audio processing at all?

    Hi Leif,

    Can’t you just release a demo version of your FM algorithm, which works for only 5 minutes or something like that?
    So people can see if it works as good as you say?

    Hi Dennis!

    When the software is ready for sale, I will definitely make a demo version. However, I already have an extensive demo you can play with. PM me your IM address (msn, aim or icq) if you’re interested.

    Leif,

    I’m very, very interested to.
    I’ve send you my email adrress.

    BTW:

    Pirate stations do care more about interference than about sound quality.
    If other people complain about your station, the goverment (police) wil take your equipment very quick. 🙁
    And you need to pay a penalty > 1200 EUR

    Wowowowowow! I am veeeeeeeery excited with this breakaway software! i wish you could allow the program to be able to have line in imput and virtual audio cable output! ….for use with airomate…

    Leif if you want freeeeeee vacations to greek island ….just call me ! i wanna meeet u definately ! Plus..i ve got 23 MBps DSL and a veeeeeeeery nice beach for all day swimming..😛

    Please publish a full working beta version for FM radio broadcasting , pleeeeeeeeeeeeease give us an "fm version" of your new program , we can PAY you through paypal and probably if you want we will be able to download next official versions of your new FM version audio proccesing programm with ONE pay fee.
    We are waiting for your beta work, please publish your beta work and you will have money if you wish.

    Hi Leif,

    What about the demo for the FM version of Breakaway? Do you still have the demo version for me to play with?
    I have send you my private email address a couple of weeks ago.

    Thanks in advance!
