Which description best fits AFL soloing mode?

AFL (After-Fader Listen) soloing mode is designed to allow a user to hear a signal after it has been processed by the fader, but it does not affect the actual output or level of the mix. This non-destructive approach means that the original signal remains unchanged, making it easy for individuals to analyze and monitor specific channels without altering the overall mix.

In this mode, the Solo Master controls the output of the AFL signals, ensuring that users can selectively monitor elements in a controlled manner while keeping the performance intact. Therefore, the correct description emphasizes that AFL soloing is non-destructive and is managed through the Solo Master, which aligns perfectly with the function and utility of AFL soloing in sound mixing or audio production contexts.
