Stereo Tool

Doesn't work at all on my system (Ubuntu Studio 12.04). Previous version (http://www.stereotool.com/download/ster ... ETA724-011) does work without any problems.

Console puts out this:

stereo_tool_beta: /lib/i386-linux-gnu/libc.so.6: version `GLIBC_2.16' not found (required by stereo_tool_beta)
stereo_tool_beta: /lib/i386-linux-gnu/libc.so.6: version `GLIBC_2.17' not found (required by stereo_tool_beta)

Your linux distribution ships a glibc that is older than the one Hans used for building the program.

That makes sense since I upgraded to the latest (beta!) Ubuntu release. I guess that's not such a good idea then... I could actually still use the old version for building - just not for testing.

You could try
sudo getlibs stereo_tool_SAlin_BETA724-019
to install all the missing libraries...

I'll also run a build on the old system, will post it here in a moment.

Same version built with older glibc:

Edit: I sometimes get a segmentation fault with this version upon startup. Restarting helps. So, I know there's a problem - I'll look into it but first I just need to know if it works in the first place.

I'm unfortunately not very experienced with Linux, so thanks for this interpretation . I only use it for experimental purposes, like the GNURadio and DAB-Stuff with mmbTools, and I'm forced to use 12.04, cause the software from mmbTools doesn't run on 13.04 anymore.
This one starts. The beep-tone doesn't have drop-outs, runs straight through until ST closes after a minute But, I'm only getting one channel in the JACK-connections for input and output, and if I connect something to the one input, no audio comes into stereotool.

Sometimes, I'm getting this message in the terminal just before ST closes after the minute Is this the segmentation fault that you've mentioned, Hans?

Ok, I need to figure out what's happening there. I took some empty CD's to my office today to install Linux on another pc here but unfortunately the image is 800 MB... Will go out to get a DVD in a moment.
I think so. I just attached a debugger and - fortunately! - the crash occurs inside my new Jack code, so it's not an error somewhere else in the software. I'll fix it.

Edit: It's fixed. And I performed a native Linux install and... I have audio! (After making a small adjustment). It's mono though - so I need to create a port for each channel, similar to how it works in ASIO.

The biggest issue is with the video: If drawing takes a lot of time the mouse doesn't respond anymore (for example when clicking on Presets when the window is large).

Ooh, good that you say it, because I forgot to mention a big issue with the graphics I have: the meters only respond when I move the mouse over the GUI-window, just like in the windows-version when display refresh is set to 0%. The oszilloscope even refreshs only every 30 seconds or so. Do I have to install some graphics-accelerator or something else on the linux-system to fix this, or is it a bug?

That would be a bug. Here it works fine - what Linux do you use?

Edit: Hm, I think I'm redrawing the window in a lower latency thread. Which is actually not allowed - but helps a lot to not disturb the audio. At least in Windows (where it's also not allowed but it works anyway). But in Linux it might not even be needed to do this.


I hope to have a working version (at least for the audio) tomorrow evening. Might be a day later.

Ubuntu Studio 12.04 LTS.
But, to be honest: it's a new and nice feeling of using ST when the meters do refresh only every few seconds. So, you automatically refer more to what you hear, and not what you see

Jack normal input and output work, connected (hardcoded) to sound card input and output. Program stops after 1 minute.

Next step is to make inputs/outputs configurable, once that works I can also enable low latency and FM outputs and SCA inputs.


Edit: Ow, built with the glibc2 again.
