Stereo Tool

Ok, I installed it in another Linux VMware machine and there it gives a segmentation fault. No idea why...

Hm. Linux is new to me, so I really don't know where to start searching. When I enter the error message that you got in Google I only find things about 64-bit Linux installs - is yours also 64 bits?

Could you try the following: Run
ldd stereo_tool_gui_BETA<xxx>-<xx>
And paste the output here.

Sure. I'm using an Ubuntu 10.10 x64 on my laptop.

Here's the output. Looks like i'm missing many things.

darkbyte@lenovo:~/Letöltések$ ldd ./stereo_tool_gui_BETA30

	/lib/ld-linux.so.2 (0xf77d8000)

But i don't get it, because i have all of the libwx libs on my system as you can see. Maybe the executable is linked the wrong way?

Okay, i think i've found out whats the problem:

darkbyte@lenovo:~/Letöltések$ export LD_LIBRARY_PATH=/usr/lib32/; ./stereo_tool_gui_BETA30 
./stereo_tool_gui_BETA30: error while loading shared libraries: libwx_gtk2u_richtext-2.8.so.0: cannot open shared object file: No such file or directory
darkbyte@lenovo:~/Letöltések$ export LD_LIBRARY_PATH=/usr/lib64/; ./stereo_tool_gui_BETA30 
./stereo_tool_gui_BETA30: error while loading shared libraries: libwx_gtk2u_richtext-2.8.so.0: wrong ELF class: ELFCLASS64

Because i'm running a 64bit OS i don't have the x86 verisons of the libwx libraries. If i force it to use the x64 libs i get an error because your executable is linked for x86 architecture.

I think there are two options:
- Compile an x64 version of Stereo Tool
- Find a way to install the 32bit libs on my system (i'll give it a go)

Mod: okay i've managed to get the missing libraries. I had to install getlibs: http://ubuntuforums.org/showthread.php?t=474790 then i executed

sudo getlibs stereo_tool_gui_BETA30

which downloaded the missing libs.

Now i get the segmentation fault as you do.

Here are the Linux versions for the latest BETA - and this time the GUI version should work without segmentation fault!

Linux command line version: http://www.stereotool.com/download/ster ... BETA510-47
Linux GUI version: http://www.stereotool.com/download/ster ... BETA510-47

Yes, it works like a charm! Thank you for your effort!



I'm using lame for decoding an mp3, piping it to Stereo Tool then play it with aplay

Great! As you may have seen it's already released.

Can i use it with jack ?
Not work with /dev/audio (/dev/dsp)

Not directly. I haven't implemented any Linux audio interfaces yet, Stereo Tool currently only processes stdin and sends it to stdout...

I think the following should work:
- Create a command line with a reader and player application
- Then connect Jack to those applications

So something like this:
arecord | stereo_tool | aplay

Or, if you just want to send audio to /dev/audio, just use aplay without Jack.

See the help text (stereo_tool -h) for some more examples.

i tried like this

arecord -r 192000 -f S16 -c2 -D jackplug | ./stereo_tool_gui - - -s settings.sts | aplay -D jackplug

works, but horrible, mine linux drivers suports only 512 sample per channel, (others application wors fine with this option, in windows 1024 and 4096 works fine) half second sounds normally, others sounds like "beeeeeeeeeeeeeeeeeeeep"

but i think it's only half way ))
