Could you explain your setup in as much detail as possible?
I don’t understand your setup, and if I have to guess, any answer wouldn’t be valid.

Hi Riplee!
Don’t change the setting yet. If you do, you will have changed two things, and thus even if the problem is solved, we won’t know whether the problem was the newer pipeline or the newer version of Breakaway!
If you keep running BA Live 0.90.69 with the new pipeline without changing the setting, we’ll get somewhere.
///Leif
I understand. It could be anything, but indeed VAC 3.12 seems to be more stable on certain systems. Glad it’s working for you again!
Best,
///LeifThe problem I’ve experienced seems to happen mostly on quad core systems. Once you open a couple of pipelines (or open one pipeline multiple times!), things can go into an extremely stuttery state where only bits and pieces of audio slowly come through.
The new pipeline version completely fixed that problem on my quad core desktop. I was quite disappointed when I discovered the problem was still there on my laptop! The parameter that the reg-key set was supposed to be on by default — perhaps something went wrong there. At Eugene’s suggestion (the VAC author) I set the key manually in my registry yesterday, and since then it’s been MUCH better.
I actually let BBP -> MpxTool run all night, and there was not a SINGLE glitch! Just beautiful.
This parameter keeps the pipelines single-threaded (single cpu affinity) when talking to windows, to avoid confusing windows (portcls.sys), which apparently has been the problem all along.
It’s possibly that Lpy’s issue is something different! How long have you had the issue?
///Leif
Not bad, Stavros!
There’s not much treble though — I wonder where it’s going, considering it’s a 50us country. Are you using New York perhaps? 🙂
I heard some bass distortion, once in a while, but it might as well have been present on the CD, and I know what an O**** processor would sound like if pushed like this — the result would not have been pretty. The voices actually sound OK. Might want to lower the bass a bit though — if the bass goes full-scale like it does now, there’s no room for anything else, and distortion results.
Check the waveform with an oscilloscope, for example regular Breakaway Audio Enhancer. You can see clearly that the bass is taking too much space, leaving no room for anything else. I also hear it, of course, just pointing out how you can see it if you don’t hear it 🙂.
It’s really not bad though. I can tell that you’re really close to the sound you’re looking for, and that’s very encouraging! All it would take to clean up the audio is 1dB less of deep bass, and that’s basically an inaudible change, but it would make a big difference in the amount of distortion.
I’m also curious what settings you use, of course 🙂.
By the way, are you feeding the encoder directly from BBP L/R output, or from a tuner?
(I’m guessing Direct, since I see no tilt)Best,
///LeifThat’s fine, Riplee — it hasn’t really changed.
Nothing particularly complicated there — Pipeline 1 in, Pipeline 2 out, both at 44100. You might want to change the output buffer size to 441 to get an even number of milliseconds per block, but I don’t know whether it will really make any difference.
Let’s see how it goes with Live 0.90.69. If that doesn’t solve the problem, that points to the Pipeline having a problem, and then this workaround might do it!
Best,
///LeifLOL 🙂
Nice one.
I don’t know about you, but 14,850 Hz is well within my hearing range, and this would drive me bonkers.
17500 would be a better idea 🙂. That, I could live with. The 15 KHz "limit" is completely arbitrary. As long as you don’t step on the pilot, you’re good.
The question is, does it really help?
Remember it can’t be very loud. Pre-emphasis dictates that a 15000 Hz tone can’t be louder than approximately -15dB, and that’s if we started with full scale (no music, only tone). If we assume we’re only willing to sacrifice 10%, that’s 20dB below full scale, so with de-emphasis we’re at -35dB. I think we can safely assume this will not make a difference one way or the other for mosquitos.
I do congratulate the station for a truly creative marketing campaign! They’ve found an excellent way to make sure lots of people keep listening to them at all times. They may not even actually have inserted the tone at all.
I’d love to see an MPX recording of this station. 😉

I rarely recommend cluttering your computer with applications, but here’s one I can’t live without:
For taking and uploading screenshots as quickly and painlessly as possible.
For creating an account to use with Shup.
Here’s how easy it is:
All it took was to press CTRL-ALT-K (shortcut for taking screenshot), Enter to upload, Enter to answer yes, and finally CTRL-V to paste the URL to the uploaded file into this message.
///Leif
I hear it. That’s really annoying indeed! My apologies.
Could you try installing Live 0.90.69 again, on top of the current version?
That way, you’ll be using older known-good Breakaway Live with the newer version of Breakaway Pipeline. If we still hear the problem, we’ll know it’s the pipeline, and I can then report the issue to the VAC author.
Could you show me a screenshot of your I/O Settings window?
Best,
///LeifSomething isn’t right. When BBP is installed, it runs a benchmark by actually running the audio algorithm. If it calculates that BBP would use more than 70%, then it tries CPU optimized mode. If that uses more than 80%, then it warns you that your computer isn’t too fast.
As I understand it, BBP installed itself in Maximum Quality mode, as this is the mode it was in. This means the benchmark must have passed at less than 70% cpu load with Maximum Quality mode. How is it then possible that CPU optimized mode is now using 80-100%?? That should be impossible, and I have never seen it go wrong in this manner.
If you shut down BBP, how much CPU is used by everything else? Do you have any plug-ins running, like encoders?
///Leif
Hm.. I don’t believe that’s possible, but I could be wrong. It’s a valid usage scenario, I just didn’t think about it.
I’ll try to think of a way to make it work, but no promises — I’m really swamped at the moment, way too many things happening at once.
Best,
///Leif
