Dear Leif,
I have a question about Breakaway Broadcast Processor. I am using version 0.90.49 right now. I am planning on buying the legal and newest version of it (as soon if i have a job again). Right now i am writing a Dutch Manual to use Breakaway Broadcast Processor in combination with SAM Broadcaster.
I followed all of the installation instructions, I installed it with Edcast & the LAME Encoder… and i am using it with SAM Broadcaster. It is al working fine, including the title streaming and everything.
I have been busy for about a week with fine tuning the processing / limiting settings for the right sound. That’s ok now, i am satisfied. But there is only one problem i can’t get solved: Sometimes there are hitches in the sound, or there is silence for 1 or 2 seconds and then the sound goes on.
I can’t get that solved. No matter what i do, i am using KS and the breakaway pipelines. It doesn’t matter if i put Realtime Priority on or off, the hitches still appear. Also changing Buffer Size has no effect, the best setting is Large. I have enough memory (2 GB), and the dual core AMD processor only uses about 50-60% of it’s capacity, with sometimes peaks till 70%. So that can’t be the problem either. Sometimes it is playing good for half an hour, and sometimes i get the hitches every few seconds/minutes.
So my questions are:
-Is this a familiar problem?
-Is this problem solved in the newest version?
-What can i do to solve it?I hope to hear from you 🙂, Greetings from the netherlands…
Dear Cybernetic Organism 😉
I’ve made enormous optimizations since 0.90.49 — the latest versions use 30% less CPU.
However, if it indeed was not a matter of running out of CPU power, then that alone wouldn’t solve it.
Using Sam Broadcaster myself, I can’t seem to completely get rid of glitches — but I’m not ready to blame SAM just yet.
Could you try the latest BBP version, and use Winamp for playback? If that still has the same glitches, it would seem to either BBP itself, or the computer is at fault. (It could for example be some driver or antivirus program locking up the system intermittently).
However, if it fixes the glitches, try SAM with latest BBP. If that glitches, it may be a problem related to SAM. If so, try the LiveLink DSP plug-in for BBP, and see if it solves the problem. You can find the plug-in here: http://www.claessonedwards.com/plugins
Best regards,
///LeifI had simular problem, try using Wave for inputs and outputs instead of KS. Use the test tone to see if it’s still happening. Otherwise like Leif said, it could be encoder related.
Test tone only gives you half of the picture, as it gets generated inside Breakaway, and thus bypasses the input device.
(Exception: The third page of the setup wizard in Breakaway Personal, which plays the test tone into the pipeline and runs the breakaway audio engine in normal mode)

Leif, i am actually wondering: What are you planning to do on the glitches problem on your own system? I think it’s very strange if SAM causes the problem itself, because if i use the LAME Encoder in SAM itself, there is no problem. The audio is running 100% smoothly.
It is not very easy to use winamp, because the server is running 24/7 so… my webradiostation would be offline. The only option is a driver which is messing, the server is running Windows Server 2008. So a minimal of software and stuff is installed on it, only the neccessary things. No anti-virus program is installed.
I can try the LiveLink, but can i still use Edcast en the encoder in Edcast that way? Another thing i am planning to do, is installing the exact same configuration of BreakAway Broadcast Processor on this PC, with the same SAM. If the glitches happen here to, i can conclude that it’s not computer related… but the problem is in SAM or in BBP itself (Or maybe it isn’t working fine with Windows Vista? Windows Server 2008 uses the same Kernel as Vista: NT Kernel 6.0).
And for Modman: KS seems the works the best for me, if i use Wave or the other option the glitches and drop-outs get even worse.
I also saw that there is a breakaway pipeline configuration tool, but i don’t want to mess up the settings in there. Cause i don’t know what i am doing that way. What happens if you turn the clock correction to 0% for example?
Cybernetic Organism, to resolve the glitches on my own problem I plan to experiment and try to isolate the problem. For example, I will route SAM to a normal sound card output and listen for glitches — and I will also create a DSP plug-in which writes all data to disk (in a separate thread). This way, the DSP disk writer will be timing independent, and if there are any glitches in the recording, I will know it’s an internal problem in SAM.
You can still use Edcast — Edcast can run from Breakaway Broadcast itself.
The "Clock Correction" option is simply a multiplier for the internal clock rate of the cable. It has no bearing on stability — better to leave it alone.
Options you may want to change in the pipeline configuration tool:
– Number of cables (pipelines)
– Volume control enabled
– Maximum sampling rate allowedBest regards,
///LeifOk… after 2 days of testing i can say a few things: I installed BBP 0.90.49 and the exact same configuration as on the server with edcast, and SAM and everything on this PC too. Still glitches and dropouts of audio.
So that means that it is not the computer or drivers that is causing the problems. I am now testing on this pc with 0.90.69 and livelink, instead of 0.90.49 with breakaway pipelines. I give you the results of that soon.
However, somebody else used 0.90.49 too with pipelines (and SAM Broadcaster too) and on his pc it was running smoothly, without problems. Also with 0.90.69 on windows server 2003 and livelink he has no problems.
The only differences is that he is running windows server 2003 on one pc, and on the other pc xp. And i am running Vista and Windows Server 2008.
There are known problems with Breakaway Pipeline (=VAC 4.x) on certain systems. It’s being worked on, but it’s a big project — apparently it’s hard problem to solve for Eugene.
You can also try VAC 3.12: [attachment=0:2417jdr6]vac312full_breakaway.zip[/attachment:2417jdr6]
Free to use for breakaway customers.
VAC 3.12 is a native wave driver, and works best with WAVE selected in Breakaway.
Best regards,
///LeifBad news, VAC 3.12 is not working under Windows server 2008 / Vista. When installing i got a feared Blue Screen of Death 👿
And yes i uninstalled the old Breakaway Pipeline in the Device Manager, then restarted the server again.
So i am running out of options, so i now use the latest version (trial version of 0.90.69) together with Livelink and SAM of course. So far so good. It was running a couple of hours on this pc without problems too. So i now just keep listening and hope the best out of it. I let you know if it runs smoothly now.
Yeah, I noticed the same thing when I tried VAC 3 on Vista. Got the Blue Screen so I assume something’s hinky when trying that with Vista.
It is still running smooth with Livelink and the newest BBP installed so… this looks like the right way to configure it if you can’t solve the glitches and drop-outs problem. If your read the VAC 3.12 manual you can see it is not compatible with Vista. I still do some extra testing tomorrow to be sure this setup is running smooth, if you want to hear my stream send me a pm.
