Thanks, guys!

AFAIK you’re not my type, but I’m flattered just the same 😀.

Here’s a new version:

Changes since 0.90.03:

When using KS output, output channel mapping is now:

Channel 1/2: Core A
Channel 3/4: Core B
Channel 5/6: Core B (was previously silence)
Channel 7/8: Core A (was previously silence)

I did this because of problems with getting good 4-channel output from my Dell Inspiron 1420 laptop.

Hehe, nope! It runs beautifully on my Atom N280 netbook, together with Traktor or Virtual DJ!

///Leif

4 stereo channels?? Maybe a pro version in the future.. What do you need that for anyway? 🙂

///Leif

Gotcha. Yeah, maybe later. What’s it worth to you? 🙂

Hi Joe!

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 algorithm

Out 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.

Best regards,

Ah! Now I see what you mean.

There’s no easy way to casually route audio between different programs. I’ve been thinking about developing some kind of solution for this, but can’t seem to find the time between every other project.. Maybe Jack for Windows is an option?

Otherwise, perhaps your sound card has built in routing features? Many do. If you could make your sound card route the output to the appropriate input, you should be able to open it as a Wave or KS device in Breakaway RTA and get the audio in that way.
