What type of audio does AFL mode operate in?

AFL (After Fader Listen) mode operates in stereo audio. This mode allows the engineer to listen to an audio signal after it passes through the fader, providing a true representation of how the audio will sound in the mix. The stereo operation is essential because it enables the monitoring of both left and right channels, which is crucial for maintaining the integrity of the stereo image in audio production.

Monitoring in stereo allows for a more accurate assessment of balance and spatial effects, which are vital components in music and sound design. Thus, selecting stereo for AFL mode ensures that the mixed audio is experienced in a way that reflects its intended depth and width. This capability is fundamental for tasks like adjusting levels, panning sounds, and ensuring overall sound quality. It is not limited to mono, which lacks the spatial dimension present in stereo, nor is it confined solely to digital formats, as the principles of stereo monitoring apply across analog and digital systems alike.
