Stereo to Mono

user-883

Since I am partially deaf, I prefer to hear my downloads in mono. Can get_iplayer download/convert episodes in mono?

This entails re-encoding the audio of a downloaded file, so it will slow down get_iplayer noticeably. For radio programmes, add
Code:
--ffmpeg-radio-opts="-c:a aac -strict -2 -ac 1"
to your command line. For TV programmes, use
Code:
--ffmpeg-tv-opts
with the same value. For 320kbps downloads from Radio 3, you may wish to add
Code:
-b:a 240k
to
Code:
--ffmpeg-radio-opts
. The default re-encoding bit rate is around 128k, which is good enough for any other programmes. The options above instruct ffmpeg (when re-muxing the raw download file into an MP4 container) to use its built-in AAC audio codec (
Code:
-c:a aac -strict -2
) to downmix the two stereo input audio channels into one output channel (
Code:
-ac 1
).
