mix all your songs down first. A good mix for all your songs is independent of the mastering process.
Mixing down means that when you’re happy about your mix for a song, export it to a single stereo wav file.
Once you songs are mixed down, create a new ardour session, and import each wav files (one song per track for example). The idea is that since the songs are mixed down, you should not apply ANY effects to the tracks. This will make ardour run without much CPU and most of the DSP processing will be jamin’s.
Then create an insert in the master bus pre-fader and connect jamin’s ins and outs to it. You should start jamin with the -p option in this case so it does not auto-connect its own ports to your system ports.
The connectivity goes like this:
insert_out > jamin_in
insert_in < jamin_out
You can activate the insert (middle mouse button click on the insert name to toggle activation on and off).
Now, in the pre-fader, before the jamin insert, add the LADSPA plugin “Jamin Controller”. This will allow you to automate jamin scene changes along the master bus timeline.
In jamin, tweak the dynamic effects to taste (overall level, warmth boost, compressor, EQ, etc). Save your tweaks in the different scenes. Each scene should make sense for songs or song parts. Be sure to rename them into something meaningful like song1_chorus_2 or song2_bridge, etc.
Then, automate this in ardour’s master bus:
click on the “a” button of the master bus header in the editor window. Pick the jamin scene controller automation, draw an automation curve in manual mode (the automation points will be floats but scene numbers are integers, never mind that, it just works). Then switch to automation “play” mode.
Playback the whole thing and enjoy jamin switching from scene to scene automatically according to your automation
