- Server: The server is the backbone of any streaming music system. It's responsible for storing and organizing music files, making them available for streaming on demand. It is where the music library resides. It can be a local server, such as a computer or a network-attached storage (NAS) device, or a remote server, such as a cloud-based music service like Spotify, Apple Music, Qobuz, Tidal, or Amazon.
- Controller: The controller is the user interface for your streaming music system. It's the device or software that you use to select and play music from your server. The controller can be a dedicated device, such as a smartphone app or a touchscreen remote. The controller communicates with the server to browse your music library and make selections. It also controls playback, allowing you to play, pause, skip, and adjust the volume. Some controllers also offer advanced features, such as creating playlists, searching for music, and accessing streaming services. The controller also manages your music collection, leveraging metadata such as album, artist, genre, and track information. Think of Roon or Audirvana. They are controllers.
- Renderer: The renderer is the device that plays the music from your server. It can be a standalone device, such as a wireless speaker or a headphone amplifier, or integrated into another device, like a DAC. The renderer receives the audio data from the server and converts it into an appropriate audio format to convert the signal to analog. In a high-end renderer like PS Audio's Bridge, that format is I2S.
