@drandyhaas built a toslink in/out delay based on a Teensy 4.0 which also has USB that could be used for audio in/out. I speculated at the time that it could be the basis for an inline EQ box since https://www.pjrc.com/teensy/td_libs_Audio.html includes DSP functions. Turning it into an inline volume control shouldn't be too hard.We badly need such a box. Alas, the reason it doesn't exist is because (as implied above), you need some sort of DSP or processor to change the volume. It would also need a display, and mute button. For bonus, it should have an IR receiver. Seems to me a more useful version would be USB in/AES out although AES to AES would be more general.
I could approach a company to build one. How much are we willing to pay for such a thing?
