What would you hear when using an After-Fader Listen?

The After-Fader Listen (AFL) technique allows a user to hear the signal after it has passed through the fader and any added effects. When you engage AFL, you monitor the signal that includes all processing applied to the sound, which means you can hear the effect of the settings as they would be in the mix. This is particularly useful for sound engineers who want to ensure that the effects, such as reverb or delay, are contributing to the overall sound properly and will sound as intended in the final mix.

In contrast, other options do not accurately reflect the functionality of AFL. For instance, hearing only the dry signal would imply you are monitoring the unprocessed audio, while having no effects at all or just an isolated track wouldn't provide a full representation of how the audio will blend with other elements of the performance. Therefore, the best answer is that you hear the effect of the settings, as it encompasses the full audio experience after processing.
