Experience a real-time JavaScript audio analyzer built with SciChart.js, the high-performance WebGL charting library. This demo shows how SciChart.js powers complex, ultra-fast audio visualisation directly in the browser—with no plugins, no native code, and full GPU acceleration.

In this video, you’ll see how SciChart.js enables advanced real-time applications that were previously impossible using standard chart libraries.

What this demo shows:

Left Panel: Live audio waveform captured from the microphone, plotted on a real-time JavaScript line chart

Top Right: A Fourier Transform (FFT) is computed and displayed as a fast-updating column chart

Bottom Right: A scrolling spectrogram heatmap visualising the audio frequency history

All charts update instantly, react to sound changes, and run entirely in the browser using WebGL

The demo highlights SciChart.js’s ability to handle high-speed, high-volume streaming data, making it ideal for audio analysis, signal processing, scientific instrumentation, and engineering applications.
