    Hi Joolka!

    Breakaway Audio Enhancer is a consumer product (for home users), not for radio stations. The product you are looking for is Breakaway Live (for web radio) or Breakaway Broadcast (for FM/AM/Digital broadcasting). They both do what you need, and more!

    Hi Werner!

    You do not need another key. Simply uninstall Breakaway Live from the laptop, install it on the PC, enter your existing key there, and it should work.

    Best,

    I can measure and post the SB Audigy 2 and the ASUS P5KPL On-Board settings. I can’t do the M-Audio — I modified the card with bigger capacitors to remove the tilt in hardware, so it’s not stock anymore 😉.

    Hi Camclone!

    I have made an extremely advanced composite clipper. 150% audio in 100% modulation, 80dB pilot protection, no pilot modulation, no loss of stereo separation, no stereo-crunch on mono audio, and xylophone-safe just like BBPs main clipper.

    It will be in a future advanced product. 😉

    LOL 🙂

    Interesting request, Camclone!

    The fact that you want to overmodulate while not losing lock, tells me you’re looking to be louder.

    The PEQ is not the right tool to use then — just use the MPX level control, either in BBP or the transmitter. This way you can achieve consistent, controlled overmodulation. 😉

    Be warned though — while some tuners can handle overmodulation, others cannot! It will depend on the IF filter in the tuner. Thus, you may be "impossibly" loud and clean in one tuner, and sound horrendously distorted in another.

    It also causes interference to other stations, and it’s also just plain illegal. I wouldn’t recommend it — there’s really nothing to gain.

    For MPX, there isn’t — and it would be pointless. MPX would use so much bandwidth, and if you have a computer at the transmitter site anyway (to serve as the other point), you might as well run the processor on that computer instead, and run MPX directly to the transmitter.

    For MP3, it probably exists — I don’t know of a suitable solution, but I will keep my eye out.

    You should be able to achieve 1 or 2 second latency over the internet — but I wouldn’t run latency that "low" as it would easily drop out. Better to run 10 second latency and have some protection against buffer underruns.

    There is a reason why Shoutcast has so much buffering — the internet simply isn’t reliable enough for audio otherwise!

    Otto, 320kbps MP3 codec will cause 10% overshoot on a peak-controlled signal, so it cannot be used.

    Only 384kbps MP2 (in my test setup!), or LOSSLESS (PCM), has acceptable peak control. MP3 cannot be used at any bitrate.

    That is, if you use MP3, it must be before the processor, not after. 🙂

    Thank you 🙂. I’d better stfu then so I don’t start preaching to the choir. One thing I’ve gotta say though:

    I made some experiments with lossy codecs and MPX a while back — trying to find a way to reduce the bit rate of a composite baseband signal (for MPX-over-internet, for example).

    It turns out that:

    Using MPEG-1 Layer 2 at 256kbps 48 kHz Stereo, but actually running the codec at 4x speed (1024kbps, 192 kHz) and then feeding only the Left channel with audio, yields acceptable results for MPX: Only 1% added overshoot, and still 40dB pilot protection.

    1024 kbps is a pretty high bitrate, but that’s actually 3:1 compression compared to the original bit rate of 192 kHz (3072kbps).

    (Although, if we were to resample the original MPX to 128 kHz sampling rate — which would be lossless from the MPX’s point of view — we’d have 2048 kbps, so it’s really only 2:1 compression).

    It was an interesting experiment, but one important fact makes it a moot point:

    You would still need a computer at the transmitter site to receive and decode the signal.

    So at that point — just load BBP into that computer instead, and be done with it already 😉. Then you can use any STL — analog, digital, bit rate reduced; all of a sudden it doesn’t matter that much anymore, because peak control is no longer an issue.

    For a dedicated, solid stand-alone PC, Windows 2000 on a Solid State drive, or Windows XP embedded on a plain old USB flash drive, makes for a nice and robust appliance.

    How do you mean to let it be a part of the bypass process?

    Do you mean Bypass should bypass the volume attenuation as well?

    (If so, a user could get blasted out of his/her chair just by clicking Bypass).

    The comparison with Steinberg is an interesting one though — they make pro products. Breakaway Audio Enhancer is not a pro product, even if the internal algorithms are pro quality. I have no clue where this misconception could possibly come from — the $29.95 price tag should make it pretty clear that Breakaway Audio Enhancer is targeted for consumers. 😉

    It’s not a matter of a level-matching bypass feature being a difficult feature to make.. Explaining it, making it understandable for people who aren’t audio professionals, now there’s a different story altogether.

    quote :

    So does that mean that as soon as I turn on ASIO I will only be able to process the physical inputs and outputs of the soundcard? (i.e. taking microphones or line inputs, processing them, then sending them back to the soundcard)

    Correct. Turning ASIO on will essentially turn Breakaway Live into a low latency hardware processor, and it will have both the advantages and disadvantages of a hardware processor.

    Hi Otto!

    I agree with Sam and Jesse’s assessments.

    A couple of questions though — you mentioned a 24-bit PCM link with a 5 GHz wifi connection.. Does this mean Two PCs with wifi cards talking to each other, or are you using some kind of hardware to accomplish this?

    If it’s two PCs, then there is really no reason to run BBP at the studio, because you will still have a PC at the transmitter.

    However: If your STL is hardware, AND your exciter has a good stereo generator built in, then you could actually run BBP at the studio, and completely avoid having a computer at the transmitter.

    The peak control (clipping) in BBP is done entirely on the L/R channel — there is no composite processing. Thus, you can use an external stereo generator and get the exact same result, provided that the it’s a good, clean stereo generator which does not do any additional filtering.

    The very easiest setup, though, is to have BBP in a stable computer at the transmitter. That way, you can use the MPX output and connect it directly to the exciter. In this case, there is no reason to do ANY processing in the studio — simply keep the level low enough to avoid clipping before the audio processor.

    The reason why many networks are using an 8500 at the studio and 2300s at the transmitter is two-fold: price + lossy STLs.

    With lossy STLs, you can’t maintain peak control over the STL. You could solve this by running unprocessed audio through the STL and having an 8500 at every transmitter, but the 8500 is a very expensive processor, and it (as evident) becomes too great of an expense even for major radio networks. Running an 8500 at the studio and 2300s at the transmitters is considered the "next best thing", but it’s quite significantly worse than having an 8500 at the transmitter instead.

    BBP makes this a moot point. It’s cleaner than any other processor, and inexpensive enough to run on every transmitter site. Problem solved 😉.

    Gotcha, Scotty. 🙂

    The dark-red bar actually indicates Band 7 Downward Expansion (roughly equal to noisegate). Gating itself isn’t indicated other than the meters slowing down or freezing.

    The answer is as clear-cut as unforgiving — it doesn’t work. It’s either or, not both.

    I do see what you mean though.. It would be nice to at least be able to run two separate instances to take care of this usage scenario. I’ll think about it — if there’s a feasible way to add this functionality in the future, I definitely will.

    Hey Texas,

    If you’re using the maximum buffer size, and realtime priority, and you’re still getting periodical glitches related to the WLAN etc, then something is *very very* wrong.

    Could it be poor drivers for the on-board audio?

    Breakaway indeed takes over and makes itself the default device, but the processed audio must still go through the regular audio driver to have a route out of the computer.

    Can you take a screenshot of the Breakaway Audio Setup window (expert mode) and post here?

    Also, what type of on-board audio do you have? SoundMax? Via? Realtek?

    Please be as specific as possible.

    Best,
    ///Leif
