Code and design files etc for a small device that delays digital audio etc.
Audio comes in on Toslink Spdif digital fiber, gets converted to electrical by DLR1150, then processed by a Teensy 4.0, then converted back to optical by a DLT1150, and back out on fiber.
The Teensy runs Arduino code with an audio library that can delay the music by up to 750 ms, in 1 ms steps.
A button and knob are used to adjust the delay.
An ssd1360 screen shows stats real time.
