Digital sources are involved in converting music in some digital form, CD, MP3, WAV or FLAC file, etc., into the analog form that your amplifiers and speakers need. See Serious Music Blog posts like Analog … Digital … What’s it all about anyway?, Digital Audio, and Digital Audio Formats for more information.
Digital source components include:
- Disc players (CD, DVD, Blu-ray Disc)
- DACs. Digital to analog converters convert a digital audio signal into an analog audio signal.
- Steaming music players. These convert digtal audio files in a range of formats delivered over a computer network into digital audio and/or analog audio signals.
- USB interfaces. These convert a USB output from a computer to a digital audio output.
