Hi everybody
i am using BAE in my karaoke shows and love it.
i think i have the standard UA generally figured out with a few exceptions
1) i’m running from Siglos Karaoke Pro (yes i saw the topic about SKP but it does not cover my confusions. when running output into pipeline, the input meter redlines rather regularly. that seems wrong from an audio standpoint. my idea was to lower the output of SKP to 7 which has the input meter floating between -18dB & -12dB…the happy zone for digital audio. am i looking at this the wrong way? should i leave SKP at 10 and not worry about the overload?2)is there any help sheet for the pipeline? just something saying “here is a setting, it does this, here is an example.
some of the information on the UI is self explanitory (BPs & SR for example), but others are new to me like “Stream Fmt Limit”.The popup help misses a lot (understandably) but there are 3 different settings, and only “Cable Range” is explained. how do the other 2 options affect BAE?3) i saw on the previous post about SKP mention of the “volume control” check box and how it fixed their issue, but i’m not getting those results. when i check the box, the audio input to BAE drops to between -54dB & -48dB. and even with the output from SKP maxed out it doesn’t change. what does “volume control” do? what am i doing wrong that it is not usable?
i know it’s a lot for my first post but i’m lost.
Hi. I believe Breakaway Pipeline is based on the original Virtual Audio Cable, whose documentation you can find here: https://vac.muzychenko.net/en/manual/main.htm
Good luck!
To be honest, I’ve never agonised over the pipeline settings. It is just used as a convenient way of trapping the soundcard output if your playout software does not have an inbuilt option that you can select. By default, it is DVD quality, so shouldn’t need any alteration.
Typically, if your playout software has an input level adjustment, I would run it 3 to 5 dB down, to give BAE AGC some headroom to work. If the input is too hot, BAE will be constantly clamping it back down and it will lose a lot of its dynamics.
thanks for the replies. i still am missing something with the volume control in the pipeline.
i have SKP sending directly to BAE, then straight out to my soundcard (Allen & Heath Zed12)
is the “volume control” using windows mixer? as of right now i am (as far as i understand) bypassing windows audio by using the KS mode and going direct out to my mixer. in system sounds, i see the meters moving on Breakaway Pipeline but not on my output device.
i THINK that means i am bypassing it?i went through and adjusted the buffers to get the jitter rate down, the input shows 10% which i think is good, but the output jitter is at 33% unless i max out the buffer size and number.
i’m using a AMD Ryzen 7 5700 processor with 32GB ram so i have plenty of power, but the jitter is very audible. what could i be missing?I believe yes that the Volume Control box has to do with windows master volume setting. It also had some other artifact on the sound quality the last time I tried it, but that was likely an earlier version of Pipeline/VAC. I think one would skip that checkbox if you want to use external volume control.
Thirty three percent is very high, so it’s no surprise that you can hear it. What happens if you just run the Wizard and let BAE decide the buffers? If you can’t get it down from 33%, it might be better to go with WAV, which is not quite so “pure”, but it just may be that your soundcard can’t handle KS very well.
I would recommend ASIO if your device supports it. Not to be confused with ASIO4ALL, which is a KS wrapper.
Hi Milky
if i let the wizard do the selections it is even worse. the jitter is between 90% and 100%.
if i max out the buffer size and max the number of buffers, i can get it down to 11-13.
wav vs ds, which is better there?Mr Klorox
unfortunately i do not have an ASIO driver (not sure if there is a REAL generic ASIO).
i appreciate you guys trying to help, it has to be something simple but i’m missing it.No problem MrKlorox, it would be a nice feature though.
any thoughts on why going to WAV output would jack up the output jitter to 900%?OK, let’s start over and see if we can figure this out.
In my situation, my playout software has the option to choose Pipeline1 as its output. I assume that your karaoke software should have a similar option to route its output.In BAE, I have the input as Pipeline1, KS, buffer 960/4 48000
The output for this exercise is my laptop Realtek speakers, KS, 960/4 48000In Windows, I have made sure to also select output properties to be 16 bit/48000.
When I run the Test option in BAE, I get an input jitter of 10% for the pipeline and 3% for the Realtek driver.
Please try to draw comparisons with your setup and let me know the figures you get.
you are correct Milky
my software output allows me to choose “Breakaway Pipeline 1”
i have BAE set as
Input = Pipeline1 KS 882/4 41000
Output = Behringer Audio KS 882/4 41000
i am attempting to avoid changing sample rate as 95% of my files are CD audio at 16/44.1kIn Windows, BAE is bypassing all Windows systems (the output audio of the sound card shows no activity in system sounds settings) but the Pipeline settings are all at 44.1k both in BAE and in Windows
when i run the test, my results are
Input jitter is between 10% & 13%
Output jitter is 33% or higherwhen i set the output to “WAV”, the input jitter stays the same, but the output jitter goes as high 900% (not sure how that is possible, but it’s happening)
Just to eliminate the Behringer, can you route BAE to your internal sound or some other device?
What happens if you ignore the Wizard’s settings and play around with the buffer settings manually? Usually, a buffer size in multiples of the sample rate works best (as in your 882), but sometimes, if the sound card has unusual frame geometry, a different buffer size works better. Start at 441 and run the test for each setting after that.
if i use the Behringer output, i get jitter at 33%-43%
if i use the built in realtek driver and laptop speakers i get jitter at 100%
just for giggles i tried using DS out (WAVE out is horrendous…minimum 100% up to 900% jitter) and get jitter out 0% with random jumps to 100%
BUT….it sounds like it is underwater with 0% jitter and completely unusable.
KS at 43% jitter sounds a hundred times better.
