Potential Customer request:

Editly provides automatic audio ducking between background music and voiceover:

https://github.com/mifi/editly/blob/master/examples/audio2.json5

We should look at if it is just as easy for us to implement such a thing since editly is also FFmpeg based.

Here is a command for audio ducking, by Emil:

ffmpeg tests % ffmpeg -i bg4.mp3 -i voice-ashley.mp3  \
-filter_complex "[1:a]asplit=2[sc][mix];[0:a][sc]sidechaincompress=threshold=0.00098:ratio=5:attack=2000:release=2000[bg]; [bg][mix]amerge[final]" -map "[final]" final.mp3
