after fader listening (audio) (AFL)

The term After Fader Listening (AFL) is used in audio technology for recording devices, mixing consoles and mixing consoles.

After Fader Listening (AFL) is a signal that is available after the crossfade and can be used tocheck the crossfade. After fader listening involves the summing fader and is particularly useful for looping in external audio effects, since the signal ratios from the unprocessed signal to the effect signal are always maintained.

If the audio signal is sampled before the crossfade, this is called pre-fader listening( PFL).
