Extract Audio from Video FAQ
How is this different from MP4 to MP3?
MP4 to MP3 always converts to MP3. This tool can copy the original audio without any re-encoding, works with many more video formats, supports multiple audio tracks and also outputs WAV and FLAC.
Why is my extracted file .m4a?
Most videos store audio as AAC, and .m4a is the standard container for AAC audio. It plays on phones, computers and most players. Choose MP3 if you need maximum compatibility.
Is the lossless option really lossless?
Yes. The compressed audio is copied byte for byte from the video. WAV and FLAC outputs contain the decoded audio losslessly but are larger.
What if the video has no sound?
You will see a message that the video has no audio track, or none at the chosen position.
Can I extract part of the audio?
Extract the whole soundtrack here, then use the Audio Trimmer or MP3 Cutter to keep the part you want.
Soundtracks inside video files
A video file is a container holding separate streams: one for the picture, one or more for sound, and sometimes subtitles. Because the audio is stored independently, it can be extracted without touching the video at all. When the audio is simply copied into a new container, nothing is decoded or compressed again, which is why lossless extraction is instant and perfect.
The audio codec determines the best container. AAC, used by most MP4 and MOV files, belongs in .m4a. MKV and WebM files often contain Opus or Vorbis, which belong in .ogg, while some MKV films carry Dolby AC-3 tracks that are saved in the Matroska audio container .mka. This tool detects the codec and chooses the container automatically.
Converting is useful when the destination demands a particular format. MP3 is universally supported, WAV is what many editing and transcription tools prefer, and FLAC keeps the decoded audio lossless at roughly half the size of WAV.
Films and recordings sometimes contain several audio tracks, for example different languages, a commentary track or separate microphones. Selecting the track number extracts the one you need.
