[Andrew]’s original broader plan was to pipe the S/PDIF data to the onboard I2S DAC, though he struggled manipulating the remaining resources on the STM chip to do so successfully. Anyone ...

S/PDIF, and more specifically optical TOSLINK, uses LED light sent down an optical fiber to encode audio data. The advantage of this over any voltage-level signals (like with regular wires ...

The DAC also uses DSD Remastering to improve the ... 4.4mm and 3.5mm inputs alongside USB-C and a combined optical/coaxial S/PDIF input. There's also a balanced 4.4mm, twin 3.5mm and a single ...
