Static Data Speed Test
Measures the time (in milliseconds) required to visualize a line graph with 5 000 000 000 data points.

results are shown in Fig.

Audio Visualization

Uses the Web audio API to extract audio data in real time.

Web Audio API has a. createanalyser() method that can be used to create a new AnalyzerNode. AnalyzerNode have methods of acquiring time domain data (waveforms) and frequency data from a fast Fourier transform of an audio signal.

time domain data is shown in the time domain diagram. The same data is also pushed into the waveform history graph. This chart shows the last 1 million samples of the audio input.

Real-time scrolling

Scroll through large amounts of random data in multiple channels in real time.

Rendered frames per second (FPS) and incoming data points per second (PPS) are displayed on the chart.
