Nice ban. Now Brian Lucey can concentrate on making music instead of wasting his time on a shilling forum.

Anyone seen this talk from the chaos communication congress?

Trigger warning: Contains some moderate amount of audiophilia. Nonetheless this is worth watching. MQA explained from a Hacker's viewpoint.

By the way, the "authenticated" part of MQA strikes me as a single benefit of this otherwise useless format. And no, it doesn't mean we should buy into it.

The cryptographic authentication process - at least in theory - would keep the rights owners and download/streaming services from applying digital watermarks further down the supply chain. Or at least consumers could notice immediately that the audio has been altered. Audible or not, i see these watermarks as a way to spy on consumer behavior and i'd really like to get rid of these. Sad thing that meridian implemented this idea first.

Maybe someone could hack up an open source solution to cryptographically "authenticate" audio using an existing format such as flac. That would be pretty awesome.

*edit*
Maybe even in a way that "survives" resampling and/or bitdepth reduction, by not considering the single "bits and bytes", but the actual resulting signal, allowing for just the right margin of error (i.e. everything that cannot be represented in redbook resolution / that doesn't fall in the audible frequency range - when playing back redbook resolution audio).

Another thought...
Maybe this is the whole reason MQA exists in the first place. I'm sure meridian holds patents on the authentication stuff and will take licensing fees from anyone who is implementing some similar technology, which i'm sure someone will want to do in the future.
