About this tool

Waveform Visualizer is a free online visual effect. Dynamic audio waveform visualization effect. Interactive eye-candy rendered live on your screen. It runs entirely in your browser — no download or sign-up needed.

Suitable for music visualization, audio testing, or purely appreciating the beauty of sound waves. The implementation principle is Fast Fourier Transform (FFT) and Canvas Mapping.

After opening the page, a waveform display will be displayed. You can use a microphone to input audio and display the sound waveform in real time. The waveform fluctuates with the volume, creating a dynamic effect. You can adjust parameters such as color, line thickness, and smoothness.

The whole process is pure front-end animation. AnalyserNode based on the Web Audio API obtains audio data and uses Canvas to draw waveforms. Supports multiple display modes: time domain waveform, spectrogram, and spectrogram.

Waveform Display is a visual effect that simulates audio waveforms. It is based on the Web Audio API and Canvas to render sound waveforms in real time.
