What Is an Audio Extractor?

An audio extractor is a tool that separates the audio track from a video file and saves it as a standalone audio file. Unlike screen recording or live playback recording, audio extraction reads the audio stream directly from the video container, preserving the original audio quality without any generation loss. Our online audio extractor processes your video files entirely in your browser using FFmpeg.wasm, ensuring your data never leaves your device.

Supported Output Formats

Our audio extractor supports 10 output formats to suit every need — from compressed formats for portability to lossless formats for archival.

MP3

MPEG Audio Layer III — the most widely compatible lossy format. Excellent for music, podcasts, and general use with great compression ratios.

AAC

Advanced Audio Codec — superior sound quality at similar bitrates compared to MP3. Ideal for modern devices and streaming platforms.

M4A

MPEG-4 Audio — AAC audio in an MP4 container. Standard format for iTunes, Apple devices, and YouTube audio.

WAV

Waveform Audio — uncompressed PCM audio with no quality loss. Best for professional audio editing and archival purposes.

FLAC

Free Lossless Audio Codec — compresses audio without losing any quality. Perfect for music archives and audiophile collections.

OGG

Ogg Vorbis — open-source lossy format with quality rivaling AAC. Used in gaming and open-source applications.

OPUS

Opus — modern low-latency codec with excellent quality at low bitrates. Ideal for VoIP, streaming, and real-time applications.

AIFF

Audio Interchange File Format — uncompressed audio format developed by Apple. Common in professional audio production.

AC3

Dolby Digital AC-3 — multi-channel audio format for surround sound systems. Used in DVDs, Blu-rays, and digital broadcast.

AU

Sun/NeXT Audio File — legacy audio format from UNIX workstations. Occasionally used in legacy applications.

How to Extract Audio from Video — Step by Step

  1. Upload your video file by clicking the upload area or dragging and dropping a file from your computer. Supported formats: MP4, MOV, MKV, WebM, AVI, FLV, 3GP, MPEG, WMV, OGV, and many more.
  2. Choose your desired output audio format from the dropdown — select from 10 formats including MP3, AAC, WAV, FLAC, OGG, M4A, OPUS, AIFF, AC3, and AU.
  3. Configure the sample rate (8 kHz to 96 kHz) and bitrate (64 kbps to 320 kbps) to match your quality and file size requirements.
  4. Click 'Extract Audio' to start the extraction process. The tool processes your video entirely in your browser — no file uploads to any server.
  5. Preview the extracted audio with the built-in player, then download it to your device with one click.

Frequently Asked Questions About Audio Extraction

1. What video formats does this audio extractor support?
Our audio extractor supports most common video formats: MP4 (H.264/H.265), MOV (QuickTime), MKV (Matroska), WebM, AVI, FLV, F4V, 3GP, MPEG, MPG, TS, MTS, M2TS, VOB, WMV, ASF, OGV, DIVX, DV, RMVB, MXF, and more. These cover the vast majority of video files from cameras, smartphones, screen recorders, and downloaded content. If your file is in an unsupported container, try remuxing it to MP4 first using a video converter.
2. Can I choose the output audio quality when extracting from video?
Yes, you have full control over the output quality. You can select from 10 output audio formats, each with adjustable sample rates (from 8 kHz for speech up to 96 kHz for high-resolution audio) and bitrates (from 64 kbps for small files up to 320 kbps for near-CD quality). For lossless extraction, choose WAV, AIFF, or FLAC format which preserve the original audio quality perfectly.
3. Is my video file uploaded to a server during audio extraction?
No. Everything runs entirely in your browser using FFmpeg.wasm (FFmpeg compiled to WebAssembly). Your video file never leaves your device. This makes the audio extractor 100% private and secure, even for sensitive or confidential video content. No signup, no uploads, no server-side processing.
4. What is the difference between sample rate and bitrate?
Sample rate (measured in Hz or kHz) determines how many samples of audio are taken per second — higher sample rates capture more high-frequency detail. Common rates are 44.1 kHz (CD quality), 48 kHz (video standard), and 96 kHz (high-resolution). Bitrate (measured in kbps) determines how much data is used to store each second of audio — higher bitrates mean better quality but larger files. For MP3, 128 kbps is acceptable for speech, 192-256 kbps for music, and 320 kbps for near-lossless quality.
5. Is the audio quality lossy or lossless when extracting from video?
The quality depends on the output format you choose: lossless formats like WAV, AIFF, and FLAC preserve the original audio quality with no compression artifacts; lossy formats like MP3, AAC, and OGG reduce file size by discarding some audio data, but with configurable bitrates to balance quality and size. If the original video contains compressed audio (e.g., AAC at 128 kbps), extracting to a lossless format will preserve that quality, not improve it beyond the source.
6. Can I extract audio from a video on my phone or tablet?
Yes, the audio extractor works on any device with a modern browser, including smartphones and tablets (iOS Safari, Chrome for Android, etc.). Since all processing happens in your browser via WebAssembly, no app installation is required. The interface is fully responsive and adapts to smaller screens for easy mobile use.
7. How long does audio extraction take and is there a file size limit?
Extraction time depends on your video file's duration, your device's processing power, and the selected output settings. Typical extraction completes in a few seconds to a minute for standard-length videos. Since processing is done locally in your browser, the only limit is your device's available memory. Very large files (over 2 GB) may cause performance issues on devices with limited RAM.
