Hi everyone, Andreas Hermann Braml wrote:
... Jack is one of those red blankets. All major distros are on their move to pulseaudio right now. As I understand it, the functionality is similar to what jack provides (correct me if I'm wrong). So although in this case, there is a really handy app - Ardour - that uses jack, I don't think this should bring in jack automatically for Lumiera sound backend, too. Well, it could, as long as there is a pulseaudio backend, too ;)
I'd like to object and give my official vote pro Jack/Ardour as invaluable partner apps for Lumiera.
I do this because not too long ago I made a small movie of a piano player. I recorded audio separately with a good microphone and pasted that audio on top of the DV raw video material.
Making the cut was okay, but audio editing is just not perfect in Cinelerra, although the program already makes a strong effort to provide good audio capabilities. Ardour is still ten times more advanced.
As it stands today, I have to make the final cut in Cinelerra, move the audio manually to Ardour, do audio post-processing there, then remultiplex that on top of the visual material. Re-touching the cut is impossible afterwards.
Instead of (again) duplicating a complete audio workstation in Lumiera, I suggest sticking as much as possible to the already difficult video processing and leave audio post-processing (possibly even mixdown and mix automation!) to an external app.
In addition to audio and midi plugs, Jack offers a unified transport system to synchronize applications. I don't know if pulseaudio has such a thing, but the unified transport is extremely useful. As far as I know, pulseaudio is thought of as a drop-in replacement for ESD, so there's probably no transport...
Anyway, there's more to Jack than just Ardour. Mastering with Jamin delivers pro-quality polished audio (also synchronized with the transport) and the jack-rack offers a simple-to-use LADSPA effects machine, so all those topics could move clear out of the way of future Lumiera developers.
We already have plenty of high-performance audio apps in the Open Source arena. The video part is what's really missing, so if Lumiera emphasizes strongly on that, users will surely flock to it!
