[linux-audio-dev] RME totalyser clone ?

[Cournapeau David]

Hi there,

    I am currently a DSP student, and want to program some stuff to 
improve my programming skills on linux plateform. As several musicians 
friends told me they would want a RME
totalyser -like software (see 
http://www.rme-audio.com/english/analyzer/totalyser.htm), I'd like to 
start with the same kind of software. It is basically a goniometer, a 30 
bands frequency analyser and RMS peak analyser.
    Here are my questions:
    - Does this kind of stuff already exist on linux ?
    - As I'd like to make the program work on linux and win32, I didn't 
see many choices for the GUI toolkit: wxwindow and gtk/gtkmm. I heard 
that gtk/gtkmm doesn't work well on win32 plateform, is it true ?
    - I feel confortable with the pure DSP part of the soft, but as I 
don't have real experience in GUI programming, the GUI part seems more 
difficult. Where to start to handle waveforms drawing, level meters ? If 
I am using wxwindow, I know I can look at the sources of audacity, but 
other sources would be useful.

    Thanks,

    David
