MP3 is safest. Pick WAV/FLAC if you'll edit further.
Lossless formats (WAV / FLAC) ignore this.
Mono is great for voice-only content.

Common uses for the extractor

Podcast & interview rips

Pull the audio from a YouTube interview, Twitch VOD, or Zoom recording for a portable MP3 / Opus podcast file.

Lectures for the commute

Grab just the audio from a 90-minute lecture video and listen at 1.5× in your podcast app.

Music-video soundtracks

Extract the soundtrack at 320 kbps MP3 or lossless FLAC for your library. Stereo preserved.

Which format should I pick?

  • MP3 — the universal default. Plays on literally every device. 192–320 kbps for music, 96–128 for speech.
  • WAV — uncompressed PCM. Largest files, but zero loss for editing in a DAW or further post-processing.
  • AAC / M4A — Apple & iTunes native. Better quality than MP3 at the same bitrate; slightly less universal on old hardware.
  • OGG Vorbis — open-source alternative to MP3. Small, good quality, plays in most modern browsers and games.
  • Opus — best-in-class for speech at low bitrates. 32 kbps Opus ≈ 96 kbps MP3 for podcasts.
  • FLAC — lossless compression (half the size of WAV). Archival-grade quality for music preservation.

Why not VLC or Audacity?

VLC can do this with a media-convert dialog buried four menus deep. Audacity needs a separate FFmpeg plugin install to even load most video containers. For a one-off extraction, a browser upload + one dropdown + download beats both — and the output is identical ffmpeg codec quality.

Video to Audio Converter — FAQ

Upload a video and pull out just the audio track — ideal for podcasts, lecture rips, voiceover extraction, music-video audio, and any workflow where you need the sound without the picture. Outputs MP3, WAV, AAC, OGG, or FLAC with your choice of bitrate.

Yes. Extraction is one-pass ffmpeg so it costs 25 tokens per second of source (150-token floor). A 3-minute music video extract costs 4,500 tokens — well inside the daily free pool for signed-in users.

MP3 (universal, great for podcasts), WAV (lossless PCM, best for editing), AAC / M4A (Apple / YouTube native), OGG Vorbis (open + small), Opus (best-in-class for speech at low bitrates), and FLAC (lossless, archival). MP3 is the safe default for most use cases.

64, 96, 128, 192, 256, and 320 kbps for lossy formats. 192 kbps is the sweet spot for speech; 320 kbps is near-transparent for music. WAV and FLAC ignore the bitrate setting because they are lossless.

Yes — pick Mono to halve file size for voice-only content (podcasts, lectures, voicemail). Stereo is the default and correct choice for music.

Any format ffmpeg can demux: MP4, MOV, WebM, MKV, AVI, FLV, 3GP, even raw TS / transport streams. Up to 200MB per file. If the video has multiple audio tracks, we pick the default track.

For WAV and FLAC, yes — lossless PCM / FLAC re-encode preserves every bit. For MP3/AAC/OGG/Opus at 256+ kbps the difference is inaudible on consumer speakers. If you need to edit the audio further, pick WAV to avoid a second-generation lossy artifact.

Single-pass ffmpeg runs at 5–15× realtime on our servers. A 10-minute lecture finishes in 40–120 seconds. The progress bar shows upload → encode → ready stages.

Only the 200MB upload cap. A 200MB H.264 1080p file usually runs 10–15 minutes; a 200MB low-bitrate podcast can be 2–3 hours. Long files simply cost proportionally more tokens.

VLC and Audacity require a desktop install, a working version for your OS, and a few clicks through codec menus. Video to Audio Converter is a browser upload + one dropdown + download. For one-off extractions the web workflow is usually 10× faster.

No. The upload is deleted once extraction finishes. The audio output lives on our CDN for 24 hours (7 days for paid users) so you can share or re-download.

Yes. POST multipart to /v1/video/to-audio/ with `file`, `format`, `bitrate`, `channels`. Pre-flight: GET /v1/video/to-audio-quote/?duration=SECS. Full Python + Node + cURL snippets at /api/.
