Sonos' new automatic tuning feature Trueplay is rolling out to the masses. The software addition adjusts the strength of various frequencies in order to compensate for a room's poor acoustics or an ill-placed speaker. The idea is that Sonos speakers should output undistorted music no matter where you put your them. Trueplay has been in private beta since October, but today is the day that it's widely available to anyone with a compatible Sonos speaker.
In our testing, Trueplay hasn't been absolutely flawless. But it's still a fantastic free-of-charge addition that, more often than not, improves audio quality significantly. It works with the company's Play:1, Play:3, and Play:5 speakers, but only through iOS devices. Android support is said to be in the works, but for now Apple devotees should be receiving an update through the Sonos Controller apps shortly.
