With the Trueplay app by Sonos, the listener always knows that they are hearing the purest sound. Using the app, the microphone on an iPhone or iPad, and a special tone emitted by by the Sonos speaker, the system analyzes the acoustic profile of any room to determine how sound reflects off walls, furnishings, glass and other surfaces that impact how sound is heard. Sonos then smartly tunes the speaker in 60 seconds so the music sounds its very best. Wow!
