An audio converter is a device or software that converts an audio signal from one format to another. Hardware audio converters include analog-to-digital converters (ADCs), which convert analog audio to uncompressed digital form (e.g., PCM), and their reciprocal partners, digital to analog converters (DACs), which convert uncompressed digital audio to analog form. ADCs and DACs are usually components of hardware products. For example, sound cards and capture cards both include ADCs to allow a computer to record audio. Sound cards also feature DACs for audio playback.
