Description
PCM
Pulse Code Modulation (PCM) is a standard for digital audio in computer and other devices
such as, digital telephone systems.
Setting the level to match the audio source's level provides the best sound quality and avoids
audio resampling. Most digital signals (HDMI or SDI sources) use 48 kHz audio. For analog
signals, 44 kHz provides a good quality audio sample.
