Re: [LAU] Strange problems with Audacity

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.
