Also called “Post Fade Listen”, AFL (After Fade Listen) is the feature that comes within the pro mixing desks / consoles which gives to sound engineers or artists the possibility of monitoring one or more specific signals / tracks alt the same level set by the fader of level control knob. Aux Sends are mostly monitored AFL.

What is AFL and How Does it Work?
AFL is a feature that allows sound engineers or artists to monitor specific signals or tracks at a specific level set by the fader or level control knob. This allows the user to control the monitoring level of individual signals without affecting the overall mix. The AFL function is often used to monitor auxiliary (Aux) sends, which are used to route signals to external processing devices such as effects units or monitor speakers.
AFL is typically activated by pressing a button or switch on the mixing console. When the AFL button is engaged, the monitoring level of the selected signals or tracks is determined by the fader or level control knob, rather than the mix bus level. This allows the user to hear the specific signals at a consistent level, regardless of changes made to the overall mix.
Benefits of Using AFL in Audio and Music Production
There are many benefits to using the AFL function in audio production and sound engineering. Some of the most significant advantages include:
- Increased Control over Signal Monitoring: AFL gives sound engineers or artists greater control over the monitoring of specific signals or tracks. This allows the user to adjust the level of individual signals without affecting the overall mix.
- Improved Sound Quality: By monitoring specific signals at a consistent level, Post Fade Listen helps to ensure that the sound quality of individual signals is maintained and that any changes made to the overall mix do not affect the sound of specific signals.
- Improved Workflow: AFL (After Fade Listen) allows sound engineers or artists to monitor specific signals or tracks more efficiently, which can help to speed up the production process.
- Improved Consistency: By monitoring specific signals at a consistent level, AFL helps to ensure that the sound quality of individual signals is consistent, regardless of changes made to the overall mix.
- Improved Communication: AFL can be used to facilitate communication between sound engineers and artists, as it allows the engineer to monitor specific signals at the same level as the artist, which can help to improve the overall collaboration between the two.
How to Use AFL (After Fade Listen)?
There are many different applications for AFL in audio and music production. Some of the most common uses of AFL include:
- Monitoring Auxiliary Sends: AFL is commonly used to monitor auxiliary (Aux) sends, which are used to route signals to external processing devices such as effects units or monitor speakers. By monitoring the auxiliary sends at a consistent level, sound engineers can ensure that the processed signals sound consistent, regardless of changes made to the overall mix.
- Monitoring Individual Signals: AFL can be used to monitor individual signals such as vocals, instruments, or drum tracks. This allows the sound engineer to focus on the sound of specific signals, without having to constantly adjust the monitoring level to compensate for changes made to the overall mix.
- Monitoring Live Performances: AFL can be used in live sound reinforcement applications to monitor individual signals during performances. This allows the sound engineer to focus on the sound of specific instruments or performers, without having to constantly adjust the monitoring level to compensate for changes made to the overall mix.
- Monitoring in the Studio: AFL is commonly used in recording studios to monitor individual signals during the recording process. This allows the sound engineer to focus on the sound of specific signals, without having to adjust the levels of all other signals. For example, when recording an electric guitar, the sound engineer can use AFL to monitor the guitar signal, so that they can ensure that it is being captured with the desired sound quality. This also allows the sound engineer to quickly make adjustments to the guitar signal, such as adding effects or changing the level, without having to go back into the mix and make changes to all of the other signals.
