"-i:tone" and "-eac:" (channel amplify) can be also useful tools when
testing multichannel routing. I.e.

-f:16,4,44100 -i:tone,sine,880,0 -o

... will produce 4 channels of sine tone. Then you can use -eac to mute
some of the channes. I.e. to mute 1, 2 and 4, you'd add "-eac:0,1 -eac:0,2
-eac:0,4". Also "-ev" can be useful to quickly check which channels have
audio in them (can be inserted at any point in the chain -- reports some
stats at the end when chainsetup is disconnected).

I'll try to do that soon. During the past few years I've been making
releases much too rarely. And of course, the less often you do releases,
the more time you end up spending per one release. So it's a kind of
self-feeding loop that leads to even slower pace of releases.
