Before you use the result
Requires HTTPS, microphone permission and a working input device. Formats depend on MediaRecorder support. The device budget allows 30–120 minutes and 128–512 MiB; keep the page open. Denied access never starts recording; this is not a screen or system-audio recorder.
Try an example
Record a short phrase and replay the MP3; if the input level stays flat, check the system microphone.
How it works
MediaRecorder captures in a codec this browser supports. A live input meter helps detect silence; after the final chunk, the microphone closes. A verified local MP3 conversion is the default, with the original recording offered if conversion fails. Inputs are not uploaded.
