How can I setup a command to get x minute segments?

[bheeshmpita]

I want to download long video into mp3 of 20min segments. The AI generated me this output
yt-dlp -x --audio-format mp3 "URL" --postprocessor-args "-f segment -segment_time 1200 -reset_timestamps 1" --output "%(autonumber)s - %(title).170B.%(ext)s"
Another functionality I want to add is to download the audio that have 1.5x speed.
How can I achieve them using ytdlnis?

ytdlnis has cutting features built inhere in the arrowed place and then add --ppa CopyStream:"-c:a libmp3lame -qscale:a 3 -filter:a atempo=1.5 -f mp3"
