This interactive WebGL visualization demonstrates the Fourier transform, converting time-domain signals into frequency spectra. It provides both a naive Discrete Fourier Transform (DFT) implementation and a faster Cooley-Tukey Fast Fourier Transform (FFT) via the jsfft library, with support for multiple window functions like Hamming and Hann. The code shows real-time computation of magnitude spectra from audio buffers using sine and cosine lookup tables, with frequency peaks highlighted.

FFT products

This example demonstrates the Fourier Transform and Fast Fourier Transform algorithms applied to digital signal processing. The visualization displays the frequency spectrum output generated by these transforms, which are implemented through custom JavaScript classes including DFT, FFT, and supporting utilities for windowing and filter operations. The rendering uses WebGL and is part of a comprehensive DSP library that includes ADSR envelopes, biquad filters, and oscillators. The code calculates spectral magnitudes from time-domain buffers using precomputed sine and cosine lookup tables.

dspFFT

This visualization demonstrates the Fast Fourier Transform (FFT) applied to a composite signal of three sine waves at 40, 15, and 25 Hz. It displays the frequency spectrum as a line chart, showing amplitude peaks at the corresponding frequencies, alongside axes labeled "Frequency Peaks of Sine Waves" and "Signal Amplitude." The code generates test data using a custom `sineGenerator`, computes the FFT with algorithms from `DSP.js` and `fourier.js`, and renders the result via D3 scales, line generator, and axes within an SVG canvas.

DFT and FFT Implementation

This visualization compares the Discrete Fourier Transform (DFT) and Fast Fourier Transform (FFT) algorithms for spectral analysis. It plots frequency peaks of sine wave data, showing signal amplitude against frequency to reveal the dominant frequencies in a combined test signal. The implementation includes custom JavaScript classes for both transforms, using typed arrays for performance, and renders the results as a line chart with D3.js scales and axes. The visualization also includes a basic Fourier transform implementation for calculating the power spectrum.

Fast Fourier Transform

This visualization demonstrates the process of applying a Fast Fourier Transform (FFT) to a signal. It plots a line chart of time-series temperature data, followed by the computation of the FFT to decompose the signal into its frequency components. The code uses `d3` for scalable vector graphics (SVG) rendering and `FourierTransform` from `fourier.js` to calculate the amplitude and phase for each frequency. The results are displayed alongside the original signal, showing the dominant frequencies present in the data.

classFFT of sine waves

This visualization demonstrates the Fast Fourier Transform by combining three sine waves (at 5, 8, and 15 Hz) into a single signal and computing its frequency spectrum. The code generates the composite waveform using `sineGenerator`, then applies the `FFT` class from `@drbagwell/dft_fft_classes` to transform 1024 sampled points, logging the resulting spectrum to the console. Built with D3.js and `observeResize` for responsive axes, the example focuses on the algorithmic FFT computation rather than rendering a visual plot.

Fast Fourier Transform Class

This example visualizes the frequency spectrum of a time-series signal, showing the amplitude of frequency peaks after a Fast Fourier Transform (FFT) is applied to a dataset of 16,384 samples. A line chart displays the frequency peaks of sine waves, with the x-axis representing frequency and the y-axis representing signal amplitude. The implementation uses D3.js for rendering and employs a custom `FourierTransform` function to compute frequency, amplitude, and phase from the data, which is sourced from a pre-loaded dataset. The visualization also includes axes and labels rendered via the `@drbagwell/responsive-viz-axes` library.

timeline - FFT decomposition

This interactive D3.js v4 visualization demonstrates how a timeline can be decomposed into its constituent frequencies using a Fast Fourier Transform (FFT). Users can drag and drop data points in the top graph to modify the time series, or use shortcuts to adjust seasonality period, seasonal magnitude, and trend. The FFT algorithm, implemented from Rosetta Code's JavaScript version, calculates frequency components displayed as bars in a lower panel. Clicking components applies an inverse FFT to reconstruct a filtered timeline, showing which frequencies contribute to the original signal.

dataFFT

This visualization demonstrates the Fast Fourier Transform (FFT) by plotting the frequency spectrum of a signal, showing a scatter plot of frequency peaks against their amplitudes. A CSV file containing signal data is fetched and processed through a naive Fourier transform algorithm, which calculates the real and imaginary components, amplitude, and phase for each frequency bin. The resulting data is rendered as a line chart of amplitude versus frequency using D3's `scaleLinear`, `line`, and `extent` functions, with axes and labels configured via the `@drbagwell/responsive-viz-axes` library. The visualization includes a gray inner plotting area and a black line trace, illustrating the spectral content of the input signal.
