Called Trueplay, the technology lets people use their Apple iPads or iPhones to map out the acoustics of a room and tweak the software in their Sonos speaker to perfectly match that room. The technology is based on the professional practice of calibrating speakers by mapping the audio profile of a room using a microphone in various places to build up a digital map of the room’s acoustics. With the Trueplay system, you slowly walk around the room for 45 seconds waving the iPad or iPhone up and down while it plays a series of sounds that Sonos sound engineers jokingly call a soggy Light Sabre.

Trueplay will soon be a feature of the iOS app used to control the Sonos system of speakers which connect to a wi-fi network and let you play the same music throughout the house, or different music in every room. Sonos says there is a Google Android app in the works, but the iOS app was much quicker and easier to develop because of the consistency of the microphones in Apple devices compared to the wide range of microphones across the Android system. Given the way the big-name consumer technology companies have followed Sonos in creating families of wi-fi connected speakers, it seems like only a matter of time before other audio companies come up with their own Trueplay system. Sonos says good luck to it’s competitors — making a hardware-software system that can finetune a speaker in any environment is not easily done. A dedicated audiophile, someone who has a near obsession with sound quality, will tell you that your speakers should be placed in a certain spot in a room — avoid big glass windows, don’t shove your hi-fi baby in a corner, and don’t prop it near furniture or fittings that can muffle or alter the sound. To get the best sound, you should sit directly in front of your
