+ Whether to request audio channel downmixing from the decoder (default: yes).

+ Useful for playing surround audio on a stereo system.

--af=<filter1[=parameter1:parameter2:...],filter2,...>
Specify a list of audio filters to apply to the audio stream. See
`audio_filters` for details and descriptions of the available filters.
