Convert Video to Audio Online

Upload any video file and extract the audio track. Choose MP3, WAV, FLAC, or M4A as your output format. Fast and free.

How it works

  1. Upload any video file. Drag a video file in any supported format — MP4, MOV, WebM, MKV, AVI, or others — into DomeScribe. The tool automatically identifies the audio track inside the container.
  2. Choose your audio output format. Select the audio format that fits your use case: MP3 for universal playback, WAV for lossless editing, FLAC for archival, M4A for Apple devices, or OGG for open-source workflows.
  3. Adjust audio encoding options. Fine-tune bitrate, sample rate, and channel configuration. If the video has multiple audio tracks (e.g., different languages), DomeScribe lets you pick the one you want to extract.
  4. Extract audio and download. Click Convert to separate the audio from the video. DomeScribe discards the video data entirely, producing a lightweight audio file you can use in podcasts, music projects, or offline listening.

Frequently asked questions

Which audio format should I choose when extracting from video?

It depends on your goal. DomeScribe's MP3 output is best for general listening and sharing due to its universal compatibility. WAV or FLAC is ideal if you plan to edit the audio in a DAW. M4A (AAC) works well for Apple devices and offers better quality than MP3 at the same bitrate.

Can I extract audio from a video that has multiple audio tracks?

Yes. DomeScribe detects all audio streams in the video container — such as different language tracks or commentary — and lets you select which one to extract. By default it uses the primary audio track.

Will the extracted audio include the full length of the video?

Yes — DomeScribe extracts the entire duration of the video from start to finish. If you only need a portion, you can trim the audio after downloading using any audio editor.

What video formats can I extract audio from?

DomeScribe accepts all major video containers including MP4, MOV, WebM, MKV, AVI, FLV, WMV, and more. As long as the file contains an audio stream, DomeScribe can extract and convert it to your chosen audio format.

Is extracting audio faster than a full video conversion?

Significantly faster. Since no video encoding is needed, DomeScribe only processes the audio stream. If the source audio codec matches your output format, the extraction can be nearly instant as it simply copies the audio data without re-encoding.
