Definitive Technology is a free iPhone app developed by Definitive Technology LLC. It offers a simple and convenient way to stream music wirelessly to the Definitive Technology Wireless Collection Speaker(s) connected to your existing stereo system. With the use of DTS's Play-Fi technology, this app provides a superior audio quality and reliability compared to Bluetooth.

Using the app, you can easily choose a speaker, select a song, and have your favorite tunes streaming throughout your entire house. The app supports various streaming options, including Pandora, Songza, Deezer, AM/FM and Internet radio, DLNA servers, and your iTunes music library, including playlists. The app automatically organizes and indexes your music for easy access.

In addition to music streaming, the Definitive app also handles the set-up of your speakers and gives you full control over volume and speaker selection. Whether you want to play music in a single room or throughout your entire home, this app makes it effortless.

Please note that the Definitive app is designed to work in conjunction with the Definitive Technology Wireless Collection and other products enabled with Play-Fi technology. It is not intended to be used as a standalone audio player.
