Audio Extraction
Pull audio from video or convert between audio formats. Pick your format, tweak the settings, and trim to the exact segment you need.
About Audio Extraction
Formats
MP3 and AAC are compressed formats ideal for sharing and streaming. WAV and FLAC preserve full audio quality with larger file sizes. Opus is excellent for voice at low bitrates.
Presets
Use Speech preset for optimal Whisper transcription compatibility. Podcast preset is tuned for voice content with normalization. Music preset preserves full quality in lossless FLAC.
Normalization
Uses the EBU R128 broadcast standard to ensure consistent volume levels. Perfect for podcasts, videos, and professional content.
How to Extract Audio from Video
Extracting audio from a video file is a three-step process with VidStudio. First, upload any video or audio file by dragging it onto the upload area or clicking to browse your files. Second, choose your desired output format and configure settings such as bitrate, sample rate, channels, and trim range. You can also pick a preset like Speech, Podcast, or Music to apply optimized settings automatically. Third, click Extract Audio and wait for the browser-based processing to finish, then download the resulting file directly to your device. There is no account required and no file ever leaves your computer.
Output Format Guide
Choosing the right audio format depends on how you plan to use the file. Here is what each supported format offers:
MP3
The most widely supported audio format. MP3 works on virtually every device, media player, and streaming platform. It offers a good balance between file size and quality, making it the default choice for sharing music and audio clips.
WAV
An uncompressed format that preserves full audio fidelity. WAV files are significantly larger than compressed alternatives, but they are the standard for professional editing, mastering, and any workflow where quality cannot be compromised.
FLAC
A lossless compression format that reduces file size by 30-60% compared to WAV without discarding any audio data. FLAC is ideal when you want archival-quality audio at a more manageable file size.
AAC (M4A)
Apple's preferred audio codec, widely used on iOS, macOS, and iTunes. AAC delivers better quality than MP3 at the same bitrate, making it a strong choice for Apple ecosystem users or anyone seeking efficient compression.
OGG Vorbis
An open-source, royalty-free alternative to MP3. OGG provides comparable quality at similar bitrates and is commonly used in web applications, games, and open-source software.
Opus
A modern open-source codec that excels at low bitrates, particularly for voice and speech content. Opus can deliver clear voice audio at bitrates as low as 32 kbps, making it an excellent choice for VoIP, podcasts, and audiobook recordings.
Common Use Cases
Extract Music or Dialogue from Videos
Pull the audio track from a music video, interview, or movie clip to listen to it separately or use it in another project.
Create Podcast Episodes from Video Recordings
Record your podcast as video, then extract the audio to distribute on podcast platforms. The Podcast preset configures optimal settings automatically.
Prepare Audio for Transcription Services
Use the Speech/Whisper preset to generate 16 kHz mono WAV files that are directly compatible with OpenAI Whisper and other automatic speech recognition tools.
Rip Audio Tracks for Remixing or Editing
Extract raw audio from video files in lossless WAV or FLAC format to import into a DAW like Ableton Live, Logic Pro, or Audacity for further production work.
Convert Video Meetings to Audio-Only Files
Reduce the storage footprint of recorded Zoom, Google Meet, or Teams calls by extracting just the audio, which is often all you need for meeting notes and reference.
100% Private -- Your Video Never Leaves Your Device
VidStudio runs entirely in your browser using FFmpeg compiled to WebAssembly. When you select a file, it is processed locally on your machine -- nothing is uploaded to a remote server. This means your personal videos, confidential recordings, and private conversations stay completely private. There are no accounts, no cloud processing, and no data collection. Once the page is loaded, the tool even works offline.
Supported Input Formats
VidStudio accepts a wide range of video and audio input formats including MP4, MOV, AVI, MKV, WebM, FLV, OGG, M4V, WMV, 3GP, MP3, WAV, FLAC, AAC, and more. If FFmpeg can decode it, VidStudio can extract audio from it. Simply drag and drop your file onto the upload area to get started.
Frequently Asked Questions
What audio formats can I extract to?
VidStudio supports six output formats: MP3, WAV, FLAC, AAC (M4A), OGG Vorbis, and Opus. Each format serves a different purpose -- MP3 for universal compatibility, WAV for uncompressed quality, FLAC for lossless compression, AAC for Apple devices, OGG for open-source use, and Opus for efficient speech encoding.
Will the extracted audio lose quality?
If you choose a lossless format like WAV or FLAC, the extracted audio is bit-for-bit identical to the original track in the video. Lossy formats like MP3 and AAC discard some data to reduce file size, but at higher bitrates (256-320 kbps) the difference is imperceptible for most listeners.
Can I extract just a portion of the audio?
Yes. Open the Trim tab and enter start and end times in MM:SS or HH:MM:SS format. Only the audio between those timestamps will be extracted. You can also combine trimming with fade-in and fade-out effects from the Properties tab for smooth transitions.
What is the Speech/Whisper preset?
The Speech preset configures the output as a 16 kHz, mono, normalized WAV file. This matches the recommended input specifications for OpenAI Whisper and similar automatic speech recognition models, ensuring the best possible transcription accuracy while keeping file sizes small.
Do I need to upload my video?
No. All processing happens locally in your browser. Your file is never sent to any server. VidStudio uses FFmpeg compiled to WebAssembly, so the extraction runs entirely on your device. This keeps your content private and means there are no file size limits beyond your device's available memory.
