Re: [linux-audio-user] offline processing

It seems that SoX is limited to the built-in effects and libsamplerate / sndfile-src is just for converting sample rates (well, you can tell me otherwise if I'm wrong, you're the author Erik :) ...). It also seems that ecasound can do the same, at least for native-to-ecasound things. What about support for offline LADSPA plugin processing, e.g. command-line through ecasound or from within a full-blown GUI thing like Rosegarden? Or, in general, setting up a bunch of applications to produce a final output file with JACK, but have it all done offline? From what I can tell, things were built to do this from the ground up, e.g. in the JACK design document there is a picture of jackd and it says "ALSA backend client and clock driver". But ... it's hard to find explicit mention of offline processing because everybody is so worried about real-time processing and low latency and all that (understandably so), whereas I'm not likely to use this machine for live audio (okay, a little bit of real-time-ness is nice in any setup, and I'm sure my machine can provide the little I need to edit tracks). Basically, I would be very happy if somebody could assure me that I don't have to worry about running /anything/ real-time in Linux audio if I don't want to, save for recording in and playing out through my sound card.
