Free Audio Visualizer — Real-Time Waveform & Frequency Display

Visualise audio in real time with waveform and frequency spectrum displays powered by the Web Audio API — no uploads, fully private.

How It Works

Connect a microphone or upload an audio file. Uses an AudioContext AnalyserNode to perform FFT analysis, rendering frequency spectrums and waveforms on HTML5 Canvas.

Tips for Best Results

  1. 1. Microphone mode shows live audio from your default input device.
  2. 2. File mode visualizes uploaded audio with playback controls.
  3. 3. The frequency spectrum shows bass on the left, treble on the right.
  4. 4. Adjust sensitivity to see quieter sounds more clearly.

Fully private: all computation happens in your browser, no data is sent to any server.

Frequently Asked Questions About Audio Visualizer

Q1How does the online audio visualizer work?

The visualizer connects an AudioContext AnalyserNode to real-time HTML5 Canvas rendering. It performs Fast Fourier Transform (FFT) analysis on incoming audio or audio files to plot frequency spectrums and waveforms.

Q2Can I visualize live microphone input?

Yes! You can choose between uploading audio files or enabling real-time microphone input.

Q3Are my audio recordings uploaded to any server?

No. Audio input and visualization calculations remain 100% local to your browser session.
