On the Wiki, `atempo` Filter states:
https://ffmpeg.org/ffmpeg-filters.html#atempo
{{{
To speed up audio to 300% tempo: atempo=3
}}}
Though available Range is only `0.5 - 2`.
{{{
Error initializing filter 'atempo' with args '3'
}}}
Only daisy-chaining works for above 200%:
{{{
-af "atempo=sqrt(3),atempo=sqrt(3)"
}}}
