LightningChart Ultimate real-time audio data visualization, 3D spectrum
SignalReader component reads a 44.1 kHz stereo .wav file and feeds the data for raw graph and spectrum analyzer. On the left side, signal data series show the waveform in scrolling and sweeping styles. On the right side, FFT is calculated on-the-fly with CenterSpace NMath routines, using multi-core technologies.
The spectrum data is visualized with SurfaceGridSeries3D, and waterfall series. Note the special effect for fading back to infinity with a custom HLSL shader.
