Why Use This Audio Recorder
This recorder runs entirely in your browser using the MediaRecorder API and Web Audio API. No audio data is uploaded to any server, so your recordings stay completely private. The real-time level meter powered by AnalyserNode gives you visual feedback to ensure your input levels are correct before you start recording.
Choose between WebM (smaller file size, modern browsers) and WAV (uncompressed, universal compatibility) depending on your needs. Recordings are held in memory and can be played back instantly or downloaded to your device with a single click.
Frequently Asked Questions
Your browser must grant microphone permission. If you previously denied access, go to your browser's site settings, allow microphone for this page, and refresh. Some browsers also require HTTPS for microphone access — localhost is typically exempt.
WebM uses the Opus codec and produces much smaller files but is not supported by all audio editors. WAV is uncompressed PCM audio with universal compatibility but results in larger files. Choose WAV if you need to import the recording into DAW software.
There is no artificial time limit. The maximum recording length is constrained only by available browser memory. For very long recordings (hours), consider using WAV format and downloading periodically to free memory.
