Yeah I’d be surprised to see AcoustID get into stream identification. Though, who knows, it’s a field full of proprietary implementations, maybe it’d be somehow beneficial if it did?
The trouble is that it’d be a completely different technology. Almost any scheme would require voluntary participation of streamers. It’d either be audio watermarking [which uses a repeating, difficult-or-impossible-to-hear audio signal, unlike Chromaprint which tries to fingerprint what can be heard] or a dedicated metadata tag. Again, many proprietary implementations of these already exist.
