Keep 15-25 cm between mouth and microphone, watch the level meter stay green (red = clipping - back off or speak softer), and record in the deadest room available. This recorder turns off the browser's echo cancellation, noise suppression, and auto-gain so the take is honest raw material. Check the input beforehand with the mic test, trim the result with the audio trimmer, and level it for podcast targets with the volume normalizer.
Press Record, allow microphone access, speak, press Stop. Play back your take, then download it as WAV (universal, lossless) or the browser's native compressed format (smaller). There is no signup, no time limit beyond your device's memory, and no upload - recording stays on your machine.
Nowhere. The audio is captured and held in your browser's memory until you download or discard it. Nothing touches a server - this page even works offline once loaded. Closing the tab discards an unsaved recording.
WAV is uncompressed and opens everywhere - editors, DAWs, transcription services - at roughly 5 MB per minute. The native format (WebM/Opus in most browsers, MP4/AAC in Safari) is what the browser records internally: much smaller, fine for sharing, but some older software rejects it. When unsure, take the WAV.
Distance and room beat hardware: 15-25 cm from the microphone, in a room without echo (soft furnishings help), consistent level. This recorder disables the browser's echo cancellation and auto-gain to keep the signal natural. Check your input first with the mic test, and verify levels afterwards with the audio analyzer.
Download the WAV and drop it on our audio trimmer - drag the start and end handles, preview, export. The trimmer and this recorder share formats, so the round-trip is lossless.
