Why you might need to separate audio from video
Sometimes you just need the soundtrack, dialogue, or narration from a video file — and you don’t want to wrestle with complicated software or sign up for another account. That’s where our audio extractor comes in.
Whether you’re a podcaster grabbing interview clips, a teacher pulling out lecture audio, or just someone wanting to save your favorite song from a homemade video, we’ve got you covered.
Podcasters and content creators
Imagine recording a Zoom call or a live event and then realizing you only need the audio portion. Instead of fiddling with desktop editors like Audacity or buying expensive software, you can simply upload your MP4 (or whatever format) and get a high-quality MP3 or WAV file in seconds. No learning curve, no ads — just your audio, ready to edit or publish.
Transcribers and note-takers
If you’re transcribing interviews, lectures, or meetings, having a clean audio file makes life a lot easier. You can feed the MP3 into your favorite transcription app or manual workflow without dragging around a huge video file.
Video editors and remixers
Want to remix a song or use a cool sound effect from a video clip? Extracting the audio track gives you a clean file that’s easy to drop into your timeline. From TikTok mashups to YouTube shorts, you’ll save time and keep your project organized.
Archivists and hobbyists
Maybe you’ve got a batch of home movies or event footage and you’d like to preserve the speeches or music separately. Our tool helps you archive just the sound portion—ideal for creating podcasts of old family events.
Tips for getting the best audio quality
1. Start with the highest-quality source you have
If your video was recorded in 1080p or higher, you’ll usually get better audio fidelity than from a low-res clip. Even if you’re extracting an interview recorded on your phone, the extractor will preserve all the original detail.
2. Choose the right format
- MP3: Great for sharing online, transcribing, and general use. It strikes a good balance between file size and sound quality.
- WAV: A lossless option that keeps every bit of audio data intact—perfect if you plan to do further editing, mastering, or archiving.
3. Mind your bitrate
By default we use a bitrate that preserves voice clarity and overall fidelity (around 192–256 kbps for MP3). If you need higher quality, go WAV; if you prefer smaller files, you can always re-encode to a lower bitrate in a separate editor later.
4. Check your levels
Before extracting, peek at your video’s audio levels. If it’s too quiet, you might need to boost the volume in an audio editor afterwards. If it’s clipping (distorting), try to find a steadier source or use editing software to normalize it before or after extraction.
