Hello Edgar,

Do you have a clue if there is an important difference between the
openSuse 10.3 realtime kernel and a JAD realtime kernel concerning audio
production? I set up an openSuse 10.3 system with the rt kernel and at
least jackd can be started in realtime mode. I didn't had the time to
try a lot more.
Another thing... i tried audacity with the 10.3 standard and realtime
kernel and in both cases i get the kernel oops [1] though audacity works
on my working machine. So i guess it has to be an audacity bug that is
connected with my chipset (firmware), not with the kernel. I'm going to
write a bug report to the audacity developers but for audio editing:
Is there a comparable jack-capable tool outthere? A tool that will
provide at least the basic editing, basic dsp (normalize, converting,
timestretch/pitchshift, eq, amp, maybe spectral view) and
ladspa-capable? Doesn't have to be a multitracker or very complex. just
something between basic & advanced.
Best regards,
Sebastian
