🟡How to use the audio filters?

The filters for audio software encoders are:

Sampling

You can manipulate the sampling rate of the input signal (which already existed before directly in the encoder)

Layout

Sets the audio layout (mono, stereo, unprocessed)

Pan

Can mute the left or right channel

Volume

Lets you set the level (10-90% or custom with dB value)

Volume normalization

FFmpeg tries to bring the noise level to an average level.
