Coming soon, and FREE:
ITU loudness meter, 1/3 and 1/6 octave RTA (in fact, it’s a TRUE rta, unlike TrueRTA which is not actually a true RTA), and oscilloscopes, just for good measure.
Light on system resources, resizable window, dockable, etc.
Useful anywhere you need large clear meters, and of course for calibrating speaker systems with parametric EQ.

Actually, coming right now.

This is barely even alpha. Try at your own risk!
Layout algorithm is basically non-implemented. If you pull the window size to extremes, or dock, it will probably crash. 🙂

Crashed the whole computer upon quitting the application. I had to reboot the computer using the power button.
Works just fin on my laptop running Vista 32bit.
Did notised that every time when I open I/O window, the list with "Interface" get doubled, open a few times and I got lots of chooices…

I had no audio playing on my system and the two top meters were running back and forth, like there was. None of the blocks were filling in. Just a black screen. Below is a cap with audio playing, the top two bars do not match/sync with what’s playing. I’ve tried KS, Wave, DirectSound. Winamp was playing in 24-bit and non-24-bit.
So does this run off of Breakaway? If so I’m a huge idiot! This is my work pc, nothing but winamp installed.
Great job Lief !!
Very nice tool to monitoring the output of a stream..
Specially, very helpfull the "Averages" selections for the spectrum analyzer.Test it on WinXP SP3 and W2K3 Server: OK 😀
Howdy!
Nice catch, Ken! Thanks. Oops 😉.
Breakaway RTA runs completely standalone. You could hook it up to anything.
Thus, I have no idea what happened there, Timmy! What audio device did you tell it to use? Did it end up picking up your laptop microphone or something like that? 🙂
When calibrating a speaker system with Breakaway Live (next release), you need an RTA and a calibrated microphone. I realized that it would be inconvenient to actually have the RTA built into Breakaway Live, as you’d then be forced to route the RTA microphone into the same computer running Breakaway, which may or may not have an available audio input for this purpose!
So, instead I just decided to make the RTA completely free. You could use it as a convenient loudness meter, or to calibrate a system with a hardware eq, or to calibrate a system with Breakaway Live. Your choice! 😉
I still have to write the layout algorithm though.. It’s a major pain in the neck — I have yet to manage to write any sort of automated procedure for this, so i basically have to code everything manually, like "if the width-to-height ratio of the window is X and there is at least Y width-pixels available then put the oscilloscope HERE", and write enough of those to cover every conceivable window size. Stuff like that. The layout algorithm for the main window of BAE/BBP/BL is over 1000 lines of code like this! There’s gotta be an easier way.
In the case of Breakaway RTA, if docked to the left or right side of the screen, it needs to show only the ITU loudness meter (since it fits the tall and skinny model). If docked to the bottom and is skinny enough, it also needs to show just the ITU loudness meter, but it could also give you the option to show ITU, RTA, Scope1 and Scope2 side by side, since those four side by side would also fit nicely in a taskbar!

Hi Appie!
Yes, it runs perfectly in Windows 2000, provided that you install a reasonably new DSound.dll. The version that comes with Windows 2000 is too old — my DirectSound code depends on a newer function in dsound.dll.
However, to be honest, this is a pretty silly dependency, considering that it also supports WaveOut and KernelStreaming. I think I will do away with it, so that it will run on any stock windows 2000 installation as well.

With all respect to Orban (the company), that meter they have is one of the worst wastes of screen real-estate ever. It makes it totally unusable if you need anything else on screen.
