About Audio Recorder
OptiPix Audio Recorder lets you record audio from your microphone directly in the browser. See a live waveform visualization as you record, with a timer counting your recording duration. Pause and resume at any time. Choose your input device if you have multiple microphones. Select recording quality (Standard, High, or Lossless). Record multiple takes and manage them in a list with play, download, and delete controls. Export as WebM (native) or convert to MP3/WAV. Your recordings stay on your device — nothing is uploaded.
How It Works
The recorder uses navigator.mediaDevices.getUserMedia() to access your microphone, MediaRecorder API to capture the audio, and AudioContext with AnalyserNode for live waveform visualization. Recordings can optionally be converted to MP3/WAV via FFmpeg.wasm.
