Record your microphone locally with pause/resume, a waveform and input meter, then play and download the actual WAV.
Your microphone waveform appears while recording.
Pause omits captured frames while keeping the microphone open. Stop saves the take and releases the microphone. Clear discards it. No microphone monitoring is sent to your speakers.
No microphone is open.
A new take replaces the previous recording only after microphone setup succeeds. Downloads stay on your device. Recording needs HTTPS or localhost and browser permission. Microphone access begins only when you choose Start recording.
Stop a recording or try the demo to hear the actual WAV.
48 kHz · 16-bit PCM WAV. Paused time is excluded. No MP3/AAC encoding, tags or automatic fades. Recording is held in memory up to a 256 MiB float-sample budget with a bounded block count. Encoding runs in a local worker; actual WAV playback must be ready before download enables. Page exit stops capture and releases the take; download before leaving if you want to keep it.
Your audio is never uploaded to a server. Capture, decoding, analysis and file generation happen locally in your browser using self-hosted code, without an account or audio history.
Only after you press Start recording and grant browser permission. Pausing keeps it open but excludes paused samples. Stop, Clear and page exit release it. Late results after a cancelled permission request are stopped.
The float-sample budget is 256 MiB, allowing a chosen limit up to 1,398 seconds mono or 699 seconds stereo at 48 kHz. A bounded capture-block budget also applies. Device memory and browser interruptions can impose lower practical limits; paused time is not included.
No. Output layout and the device input are separate. Mono averages available L/R; stereo duplicates a mono input if necessary. Browser processing toggles are requested preferences, with delivered settings shown when available. No raw-hardware fidelity or calibrated meter claim is made.
48 kHz, 16-bit PCM WAV. Out-of-range sample clipping is counted. There is no MP3/AAC encoder, automatic fade or metadata preservation. Download becomes available after the actual WAV preview loads.
