From the post
First i thought i'd just post this after the 2 channel version to the same post - but the permalink to that post is "2-channel-mixer". So. Sorry for "double" post, but here's one for NoNE.
Here's the revised version with more gain/level from the mixer opamp. I'll revise the 2 channel version too...
