Re: [linux-audio-user] offline processing

I have been teaching myself a little bit about mastering using jack and jamin. My system is a PIII 550, I'm using the onboard YMFPCI sound card. There was most def a learning curve but I did manage to finish the proof project that I was working on. So unless there is some specific technical difficulty with your particular combination of hardware then doing dsp in real time on your 800 MHz machine shouldn't be too difficult. I did have some success running ecasound -> jamin -> ecasound + PCM out to monitor the mastering process. There was some assorted weirdness with the tracks that I recorded this way though. To see if what I was trying to do was even possible I then went to alsaplayer -> jamin -> ecasound. This seemed to eliminate some of the difficulties I was having with using eca for playback and recording. Using 4 periods of 4096 samples was almost entirely stable but I did still get the occasional xrun, especially when processing tracks ~60 mins. On the whole it was doable though. And there are still refinements to be made to the process I used, and doubtless a dozen other ways to use Linux for dsp. After I take a little break and get the caught up on other things I'll bother you all with some of the questions that arose. Ciao, Barton
