Ecasound
Ecasound is a software package designed for multitrack audio processing. It can be used for simple tasks like audio playback, recording, and format conversions, as well as for multitrack effect processing, mixing, recording and signal recycling. It supports a wide range of audio inputs, outputs, and effect algorithms. Effects and audio objects can be combined in various ways, and their parameters can be controlled by operator objects like oscillators and MIDI-CCs. A versatile console-mode user interface is included in the package.

This actually does exist already: the "-ge:args" option.
See ecasound(1) man page for more info.
nice work!
This is the only thing of its kind that I've found so far,
which actually works. And it works well.
My current interface to it is a bunch of shell scripts
called "record", "mix-two-tracks", etc.
I see that there are several GUIs out there but none
that are really good. (Maybe if there was a really good
one, there wouldn't be any others.)
What would be nice is a tool with a threshold gate that
triggers recording (or maybe there is one??)
And maybe something like a "circular file" which emulates a tape on which you can record at most
n seconds of new material, after which the material
at the start of the loop is overwritten. Actually it would
be nice if ext2fs supported this sort of file. Would be
nice for logs too. Hm, maybe I'll write one..
