I'm trying to translate digital audio (via the S/PDIF output of an MPC 1000) to analog output(s), preferably 4 mono unbalanced outputs, but even just one stereo TRS output would suffice.
The audio outputs need a 0-5v range (around 16-17 dBu).. (A precise attenuator for the output range would be handy, but it's not necessary.)
The trouble is that I need the outputs to be DC-COUPLED. I can't have any high-pass AC filtering on them.
The Arduino audio shield kits I've seen all boast AC-coupled audio output. Or they at least offer "filtered" DC output. As do the pre-made options I've seen and most DACs on the market.
But I need straight-up DC coupling. I'm using the audio to control synthesizers, which requires DC control voltage.
I am awful at soldering, and I don't enjoy doing it. Sad but true.
However, I don't need ultra high fidelity with this project.
It's just to control some synthesizers using my MPC, and I don't want to shell out $250+ on a fancy cv converter. (I understand the cost of boutique hardware, I don't understand the lack of a cheap alternative.)
I'd be grateful for any/all suggestions.
Heck, I'd be willing to pay someone (a reasonable fee) to do it.
Thanks so much!
