Howdy!
Using 44100 or 48000 Hz sampling rate limits the top frequency response to 20 KHz. Luckily for us human beings, that covers our entire hearing range for the vast majority of us!
When I was 9 years old, I heard up to 21 KHz. I’m a little older now (31), and hear up to 18 KHz. How high do you hear? 🙂
24-bit does have definite advantages though, for certain scenarios, and I may add support for it in the future if there’s a real need. However, with any popular music released the last 10 years, it’s pointless — in fact 12 bits would be plenty enough to accurately reproduce todays compressed and distorted masters.
So in short, indeed Breakaway supports 48000 hz 16-bit maximum, but no, you’re not losing any quality from it 🙂.
Best regards,

Thank you for your comments!
1) High sample rates for playback are necessary in certain scenarios. For example when using Breakaway Broadcast to output MPX, 192 kHz is required, as the necessary stereo subcarrier has information up to 60 kHz. However, for regular audio played for human beings, 44.1 kHz sampling rate covers the entire human hearing range. This is a subject one could spend a lifetime arguing, but one thing is for sure — with source material coming from CDs, there’s no possible benefit from increasing the sampling rate. Disadvantages would include increased CPU usage, more complicated code base (more bugs), and paradoxical choices, such as:
What’s the multiband compressor supposed to do with the ultrasonic material which may exist in certain sources and not others? The options I can think of are:
A) Include it in the top frequency band, thus allowing ultrasonic content to affect audible content
B) Put them in their own frequency band, thus allowing an strong unnatural boost of ultrasonic content, since there’s usually so little of it
C) Put them in their own frequency band but couple this band to the top audible band
or
D) Filter it out as it enters the algorithmOut of those options, C) and D) are the only ones that would be acceptable to be, but with the dubious benefit, well..
2) This would be possible in theory, but there is a big problem with it: The delay wouldn’t be constant!
As it is, whether you’re using 4-channel KS or 4-channel ASIO output, if you’re using the 4-channel ASIO input driver, delay will be identical for both decks. If we split them up, one of them would have to go through the asynchronous sample rate converter, and then that one would be delayed more. In any other environment, this wouldn’t matter much, but believe it would cause serious problems for a DJ trying to beatmatch — especially for someone who is using internal mixing in the DJ software, and thus using the two outputs in Breakaway DJ as Master/Cue as opposed to Deck A/Deck B! Imagine the trainwreck..3) Yes, absolutely, because, Breakaway RTA doesn’t need to be connected to Breakaway DJ in any way — Breakaway RTA just needs a measurement microphone. It doesn’t even have to be on the same machine as Breakaway DJ.

Did you also set your player to play through Breakaway Pipeline 1? I believe that’s what’s missing.
If you want to pass audio from all players to Breakaway Live, you can set Breakaway Pipeline 1 as the default sound device in Windows.

LeifKeymasterThank you kindly! Comments like this make it all worth it 🙂.
I guess I’d better get it into our online store then. Might this be the first time in history that an Alpha version has no reported bugs? 🙂
///Leif
LeifKeymasterThank you very much! 🙂

LeifKeymaster[quote author=”X-Hosted”]Is it realy the external encoders that make it instable? [/quote]
Maybe not, but it sure makes it a pain in the ass to set up and configure
[quote author=”X-Hosted”]Why do you recommend to use edcast with BA anyway Leif?[/quote]
Because it’s the one shoutcast-compliant encoder (other than Leifcast) that lets you choose a really good codec. I wholeheartedly agree that it’s a buggy piece of something, though.
///Leif
LeifKeymasterWell.. I’d certainly love to, but it’s more a business-development issue than an engineering issue. You can guess which one of the two I’m good at, and which one I’m not. You never know what the future has in store though! Things are happening behind the scenes, so who knows.. 🙂
///Leif
LeifKeymasterAH! Yeah that wasn’t clear at all. 🙂
Yes, you absolutely need ASIO, and by that I mean a sound card with ASIO support. ASIO4ALL need not apply — that’s an ASIO -> KS translator, and Breakaway supports KS internally.
The AP192 should be able to provide excellent latency — try buffer size 128 or so.
///Leif
LeifKeymasterGotcha. Yeah, maybe later. What’s it worth to you? 🙂

LeifKeymasterHi Adam!
I’m not sure what you’re asking. CPU requirements? Recommended audio card?
Breakaway Live on my netbook (Atom N280, Realtek ALC272) with my Sennheiser HD650 headphones plugged into the headphone output works wonderfully and sounds equally wonderful. Not very high system requirements there 😉.
I’m not sure if I’ll be to either Broadcast Asia or NAB this year, but who knows! I have attended NAB several times previous years, and Broadcast Asia once.
///Leif
LeifKeymaster4 stereo channels?? Maybe a pro version in the future.. What do you need that for anyway? 🙂

LeifKeymasterI did, and Plutonium sounded fine to me. It’s possible that Eruption simply has too much multiband drive, from the extreme input AGC settings.
///Leif
LeifKeymasterHehe, nope! It runs beautifully on my Atom N280 netbook, together with Traktor or Virtual DJ!
