How the soundtrack becomes an MP3
The page reads the sound with the browser's audio decoder and encodes MP3 with LAME. Bitrates run from 64 kbps for a voice note up to 320 kbps for music. Surround sound is mixed down to stereo or to mono.
A sample rate the MP3 format leaves out is lifted to the next rate LAME accepts, and a rate above 48 kHz is saved at 44.1 or 48 kHz. The length you set is the length of the MP3. Browser support for this page was checked on 27 October 2026.

Questions
Which videos can I open?
MP4, MOV, WebM and MKV, plus the other containers this browser can read. The sound needs a codec the browser decodes, such as AAC, Opus or MP3.
Why is the bitrate sometimes lower than I chose?
MP3 caps the bitrate at low sample rates. A voice recording at 8 or 16 kHz saves at 64 kbps or below, and the page says so when that happens.
Can I keep one part of a long video?
Yes. Drag the start and end handles, or type times as minutes and seconds, such as 1:05.5. The MP3 contains that span.
Where does the MP3 encoder come from?
The page loads LAME through lamejs 1.2.1, a separate file under the LGPL, the first time you save an MP3.
