Is there a chance dBpoweramp could incorporate ACRCloud for recognition and as a metadata source.
I use their broadcast monitoring (a different but related service) on another project and it's good.
It costs but would be worth it to me. And I would be OK with buying the service from ACRCloud and configuring API credentials in dBpoweramp.
