[sdiy] Panning with LM13700

[Tom Wiltshire]

Yeah, I've seen that Thomas Henry one. The same idea appears in the SSM2045 datasheet. But this design is -6dB centre, constant level, not constant power. I was looking for something that does a smooth pan of a mono input. The -6dB pan sounds like it starts in your left ear, then shoots off somewhere in front of you, and then zooms back into your right ear. I find it quite distracting, and it seems to narrow the stereo field for me.
