Why Extract Audio from Video?
Common reasons include saving a recorded lecture as an MP3 to listen on the go, extracting a music track from a concert video, pulling audio from a podcast video for an audio-only version, or extracting background music you recorded yourself.
Lossless vs Lossy Extraction
Lossless stream copy extracts the audio track exactly as it exists in the video container with no re-encoding — quality is identical to the source. Re-encoding converts to a different format (MP3, WAV, FLAC) which involves re-encoding and for high quality results should use 320 kbps for MP3.
