Record from your microphone and export a clean WAV or MP3 file. Recording, conversion and download all happen locally on your device.
The Audio Recorder records from your microphone in the browser and gives you a clean MP3 or WAV with no software to install. A live waveform shows your level as you speak, so you can catch a too-quiet mic or a clipping input before it is too late.
Afterwards the editor opens with the recording loaded: trim the lead-in and tail, remove rumble, normalise to −16 LUFS, then download. Nothing leaves your device.
Audio is captured with the browser’s MediaRecorder API (Opus in WebM, Ogg or MP4 depending on the browser) from a MediaStream with echo cancellation, noise suppression and auto-gain individually switchable — they are off by default for the most natural sound. The recording is decoded to samples, so the same editor and encoder as the other tools can trim and export it.

No — it stays in your browser.
Limited by memory; hours are fine on desktops.
No — recording, format conversion and download all happen locally in your browser using the MediaRecorder and Web Audio APIs.
Browsers require explicit permission before any website can access your microphone. ToolsCrow never stores or transmits your audio.
WAV gives you the exact, uncompressed recording. MP3 is smaller and easier to share, with a small, usually inaudible quality trade-off.
This tool runs entirely in your browser using the Web Audio API. Nothing is uploaded, stored or shared — there is no server to send your file to, so it works offline once the page has loaded.
Hit record, hit stop, download. WAV or MP3, your pick. Everything runs locally in the browser so nothing gets uploaded anywhere, which is the main reason I kept using it over other recorders. No account, no waiting, just works. Simple and fast, exactly what a recorder should be.
