Choosing a bitrate
128 kbps is plenty for speech: podcasts, lectures, meetings and interviews. It keeps files small, at about 1 MB per minute.
192 kbps is a good all-round choice and the default. 320 kbps is the highest MP3 quality and makes sense for music when you want the best result, at about 2.4 MB per minute.
A higher bitrate can’t restore quality that wasn’t in the video to begin with. Phone videos usually carry 128–256 kbps AAC audio, so 192 kbps captures nearly everything.
When to pick WAV instead
MP3 is compressed and ideal for listening and sharing. If you’re going to edit the audio further, for example clean up noise, mix it or master it, extract WAV instead so you don’t compress it twice.
Common uses
Turn a recorded lecture or webinar into something you can listen to on a commute. Send the audio of an interview to a transcription service, which is usually cheaper and faster with a small MP3 than with the full video. Keep the soundtrack of a concert or performance you filmed, or save a voice note that was recorded as a video.
Private by design
ClipFit processes your video inside your browser using FFmpeg compiled to WebAssembly. The file is never uploaded, so there’s no waiting for transfers and no copy left on a server. Once you close the tab, nothing remains.
Questions
Can I extract audio from a long video?
Yes. Audio extraction is fast because only the sound track is processed. Files up to 500 MB are supported.
The video has several audio tracks. Which one is used?
The first audio track. That’s normally the main language or the mixed soundtrack.
Can I use this to download music from YouTube?
No. ClipFit only works with files already on your device. Make sure you have the right to use the audio you extract.
Will the MP3 play everywhere?
Yes. MP3 is supported by every phone, computer, car stereo and music app, which is why it’s the default here. If you need lossless audio for editing, choose WAV instead.
