Hello all,
I am sorry I did not noticed messages here.
I uploaded the ZIP file with actual code for AudMeS (honestly during last 6 months I did not have a time(and reason why as well) to spend any hour to continue.
Sorry for inconvenience. Next time please contact me directly through email.

My personal ToDo list follows:
ToDo
General:
- clean up RWAudio file
- porting to Linux - ALSA architecture
- extend OscopeCtrl to add more traces
- extend OscopeCtrl to add zooming of waves
Generator:
- BUG - if frequency is not dividable by 5 there are clicks in sound
- finish generator - other waves
Oscilloscope:
- triggering
- better X-scaling of oscilloscope
- better Y-scaling of oscilloscope
SA:
- better Y-scaling of spectrum analyzer
- averaging in spectrum analyzer
- add switch between CH1 and CH2 ( left/right)
- extend the range of SA to 20kHz - isn't it done ??
>Generator:
>- BUG - if frequency is not dividable by 5 there are clicks in sound
>- finish generator - other waves
I want to generate independant (but close) frequencies, but notice that the L and R generators CAN sometimes have different STEP locks
eg I get 315-340-365Hz on left, and 315-335-360Hz on right ?
Can that be fixed ?
Can Freq SET precision also be finer ? - either an optional direct
numeric entry (to 0.1Hz?), or
perhaps a Shift+Arrow for finer steps
It is also possible to go below 20Hz ?
(I'm not sure if there is a sound card limit there)
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
>- BUG - if frequency is not dividable by 5 there are clicks in sound
Regarding Generator, I do not know where is the problem with non-5Hz steps. Maybe you can have a look and/or fix the code (or somebody else) - it is available in the Download section.
>- finish generator - other waves
what waves do you want ?

yes, this can be done
> It is also possible to go below 20Hz ?
Normally sound cards are limited to around 50-70Hz. Better cards have the limitation around 20Hz. But I currently do not know any card able to reproduce 10Hz or even lower. Furthermore it is quite dangerous for your loudspeakers. How do you want to have such low frequencies ?
Thank you for your interest,
Vaclav

Hi,
Where is the code, project looks interesting
I agree, that this project looks very interesting. As i see it, is there no similar free program for Linux ,yet.
When you provide the sources, someone else can help you to integrate ALSA. You don't need to make the work all by yourself.
You can provide the sources either as SVN/CVS or simpler as downloadable zip or gz file.

- add trace selector
Nice looking system :)
Can I request some minor fixes :
