It would be nice to have the song identification feature on iOS while on standby like the Pixel 2 does.

I still can't understand how that feature works. They stated that everything is done locally on the device, so privacy is not an issue. But how can they host a huge catalog of songs fingerprints without blowing the storage? Are they only saving the top charts?

My understanding is that song fingerprints are tiny, so it's not too prohibitive to store an entire catalog of them on the device.

Yeah it misses out on a lot of indie stuff

They only store a catalog of the most popular songs. (Where 'most popular' is determined by your geographical location). This catalog is periodically updated.

According to a friend who works at Google, they only store a catalog of ~20k popular songs that updates periodically. Fingerprints are small, so an archive of that size isn't too big.

That's weird, because the AcoustID database is over 160GB: https://acoustid.org/database

Then again, it does have 48M fingerprints, so that's only ~3.3KB/fingerprint. Maybe Google has a decent subset in a reasonably-sized package.

The Shazam thread from the other day said it was only 60MB worth for like 10 or 20k songs
