Extract Audio from Video

Save the audio track from any video as a clean MP3, WAV, M4A, AAC, FLAC, or OGG file.

Pulling the audio out of a video is one of the most common editing tasks — for podcasting, voiceover review, transcript preparation, or simply saving a song from a music video. Media Manipulator extracts the first audio track from any common video container and re-encodes it into the format you choose, with no quality loss when the source already matches.

How to use it

  1. Upload your video

    Drop any MP4, MOV, MKV, WebM, AVI, or M4V file.

  2. Pick an output format

    MP3 plays everywhere; WAV is lossless; M4A/AAC is a compact default.

  3. We extract

    FFmpeg pulls the first audio stream and encodes it cleanly.

  4. Download

    Save the extracted audio in your chosen format.

What this tool does

  • Extracts the first audio stream from MP4, MOV, MKV, WebM, AVI, and M4V containers.
  • Encodes output as MP3 (libmp3lame), WAV (pcm_s16le), M4A/AAC, FLAC, or OGG (libvorbis).
  • Detects videos with no audio stream and returns a clear error instead of producing an empty file.
  • Preserves the original duration and sample rate.

Why it matters

  • Audio extraction is the first step for podcast repurposing, transcription, music sampling, and voiceover review.
  • Having a clean, format-specific audio file decouples the audio from the original video container.

Common use cases

Advanced details
  • We pre-check the source with ffprobe so videos without an audio stream return a useful error instead of an empty file.
  • MP3 is rendered with libmp3lame at quality preset 2 (≈190 kbps VBR) — the typical sweet spot for speech and music.
  • M4A/AAC uses the native AAC encoder at 192 kbps, suitable for both speech and music.

Frequently asked questions

  • Can I extract audio from an MP4?

    Yes — MP4 is the most common case. We also support MOV, MKV, WebM, AVI, and M4V.

  • What audio formats can I export?

    MP3, WAV, M4A, AAC, FLAC, and OGG.

  • Does extracting audio reduce quality?

    Output quality is determined by the format you pick. WAV is lossless. MP3 / AAC / OGG are lossy but at our defaults they sound essentially identical to the source for most listeners.

  • Can I extract audio from a video with multiple audio tracks?

    We always pull the first audio stream. If you need a specific alternate language track, please reach out and we will look at adding multi-stream selection.

  • What if my video has no audio?

    We detect that up front and return a clear error message instead of producing an empty file.
