How can you only extract 30 seconds of audio using ffmpeg

Use the following command:

ffmpeg -ss 0 -t 30 -i file.mp3 file.wav

• -ss 0 – Start at 0 seconds
• -t 30 – Capture 30 seconds (from 0, so 0:00 – 0:30). If you want 1 minute of audio, use -t 60.
• file.mp3 – Input file
• file.wav – output file
