ffmpegHow to speed up audio 4x

Since atempo filter allows max 2x speed increase, we use multiple atempo filters to bypass that limit:

ffmpeg -i in.mp3 -filter:a "atempo=2.0,atempo=2.0" -vn out.mp3ctrl + c
-i in.mp3

input MP3 file


applies specified audio filter


allows to change speed of audio (allows values from 0.5 to 2.0)


speeds up audio speed twice


skip video (process only audio)


resulting file
