-map 0:#
1 for English, 4 for German. I don't know what other number is for which language. Use MPC and change audio track to listen.

-map 0:0 is the main audio track (non-voice). Do not remove this!

First -map 0:0 tells ffmpreg to not touch non-voice track (main audio like sounds and stuff)
Second -map =:# tells ffmpeg to not touch selected voice audio track
In the above example ffmpeg removes all audio tracks with the exception of 0 (main audio track) and 4 (german audio track)
-acodec copy tells ffmpeg to copy audio source (it doesn't change stuff like bitrate, hz, etc.
-vcodec copy is the same for video source

If you want to leave 2 voice languages, for example english and german, add a third -map option
ffmpeg -i "C_Spyro03_TheEscapeOutro.mp4" -map 0:0 -map 0:1 -map 0:4 -acodec copy -vcodec copy "Processed\C_Spyro03_TheEscapeOutro.mp4"
