I’m not sure of the correctness, but I see the author adjusting eq in the source, this is from the “BASF LH Extra C90” preset:

> highpass=f=50,lowpass=f=13000

> equalizer=f=500:width_type=q:width=0.8:g=-1.2,equalizer=f=6000:width_type=q:width=0.7:g=-4

The Verge's headline is misleading

> Bose is open-sourcing its old smart speakers

Bose, though, makes a more nuanced distinction in their announcement, which is linked to in the article

> Open-source options for the community | We’re making our technical specifications available so that independent developers can create their own SoundTouch-compatible tools and features.

Bose never claims they're making the speakers open-source, it's lazy reporting by The Verge. They're just making it a little easier for the community to build stuff if they want.

While actually releasing the source code for the speakers would be best, there might be some legitimate business concerns. To me this is a step in the right direction, and their official announcement accurately represented that.

If the key and encryption mechanism are ever leaked, those opaque external IDs can be converted easily back to sequence numbers, and vice versa, which might pose a risk for you or your users. You won't be able to rotate the encryption key without breaking anything external that tracks those encrypted IDs... third party services, SEO, user bookmarks, etc.
