Whilst I would avoid inflammatory adjectives like "stupid", I tend to endorse camclone’s comments. It’s the same reason why I have steadfastly avoided using laptops for DJing – because everything is crammed into a conveniently portable carry case, but at the expense of expandability, cooling and (in some cases) performance.
Sure, if your studio is a lined packing case, go for miniaturisation, but, if you have the space, think BIG.
I seem to recall Leif saying that video hadn’t been optimised until the release of Breakaway DJ. I could be wrong, but I use BADJ and can watch videos on a three metre square screen without perceptible synch problems.
Having said that, the performance of your PC has a lot to do with latency. Not only the sound card/chip, but also your video card, RAM and CPU performance play a part. Having lots of video memory is less of an issue than the speed of the RAMDAC and numerous other "techie" options. The PC on which I run BADJ is optimised and dedicated to my studio environment.

Also, since you have an M Audio card, how about just using ASIO instead of KS?///Leif[/quote]
That would be my ignorance, because I thought that KS bypassed all the Windoze crap. OK, I’ll try it.

That doesn’t make sense at all 🙂. How high was it when it was high?///Leif[/quote]
As I said elsewhere (didn’t mean to hijack this thread), when I first installed BADJ, I just cranked the buffers all the way to 48/2 and reported perfect sound and video synch. I was tinkering for other reasons, and pressed the TEST button. At 48/2, the jitter reading was 300%. Some experimenting found a sweet spot at 512/2, yielding 10% jitter. However, after a couple of hours playing, I noticed the odd glitch – just a very brief pop, but there nevertheless. I switched back to 48/2 and it was fine for the rest of the night.I haven’t had much time to experiments since, but one thought I had is that the M-Audio 192 card has its own buffer adjustment, which has always been set to the minimum allowable (64). Could there be some over or under-runs being introdced because of this?
Thanks guys.
Any thoughts on my other post about the jitter being high but the audio was stable, and when I lowered the jitter (by increasing the buffers), the audio popped now and then?[quote author=”Leif”]Fewer buffers = less delay, so if 2 buffers works reliably, that’s excellent.
ASIO always uses two buffers — i.e. when the sound card is reading from buffer 1, the audio app is writing to buffer 2, and vice versa.
Kernel Streaming drivers are not usually reliable with less than 3, but since 2 works for you, consider yourself lucky 🙂.

Now I’m confused. When I first installed BADJ, I just set the buffers to the lowest levels. Everything worked, so I left it that way. I was "tinkering" the other day, and hit the "Test" button in I/O configuration. I noticed that the jitter was running at 300% (!), so I went through the process of trying various buffer combinations. 512 dropped the jitter down to 10%, so I left it set at that. Later that evening, I noticed the odd pop or crackle coming in, so it seems that I get better performance even with 300% jitter.
In a related question, I use an M-Audio audiophile 192 soundcard, and it has it own buffer settings. I have always had it set to the minimum (64). Would there be any advantage in aligning it with whatever buffer count works best in BADJ or is this paramter ignored?[quote="Leif
I thought I did 🙂. What are you missing exactly?Best regards,
///Leif[/quote]You certainly did, and I am not complaining. However, I am more results driven than price driven, and would rather pay more for a product that is dynamic and kept up to date than one which is seen to be stable and therefore "complete".
My "poor cousin" comment was because I had already admitted a liking for the Zenith preset in the thread where JesseG announced it and, if it really is an improvement on its already great predecessor, then I assumed its roll-out would automatically flow on to all products in which it is currently installed.
So is BADJ going to become the "poor cousin" just because you designed it for big speakers in "DJ" venues?
I bought it because I live in a situation where most of my audio experience is video tracks on a very big home theatre screen and I needed the program to fine tune my audio enjoyment without introducing visible latency to my A/V experience. I love it, but find the limited number of presets a bit of a "downer".
Maybe I bought the wrong product? Give me something that provides the very low latency for video display, with the supurb audio manipulation you provide.Excellent! I’ve used Zenith since I bought BADJ and I love it.
I have to show my ignorance. How does one go about installing a new or replacement preset?Bring it on!
I’ve not had the same problem at all, powerjam. However, I’m running on a desktop with an internal PCI card (M-Audio). I recall that you were having ASIO glitches before you installed BA-DJ, so there must be some sort of timing issue that Breakaway masks most of the time.
I understand the principal of buffers, and the need to keep them as small as possible, but can someone please expain the "Buffer Count" option, and whether that should be smaller or bigger. I have Buffers at 64 and buffer count at 2, and everything seems to be working fine.
