Minimalistic and efficient FFT implementation
Typeface for drawing waveforms and data
Class for rendering audio stream data for frequency/time domains. Browser/node.
Finds patterns in ndarrays
FFT-based windowed spectrum analyzer
A C++ node.js module that allows manipulating audio streams from/to soundcards and work with the fft of the signal etc.
Minimalistic and efficient FFT implementation
Translates ndarrays using sinc interpolation
Multiplies polynomials together using an FFT
Ultra-fast real/complex FFT with simple interface
Simple pure Javascript implementation of the Cooley-Tukey algorithm. Note: fft-js was chosen as the name since a lot of the FFT implementations on NPM at the time this was published were wrappers for Ruby or C.
Fast Fourier Transform algorithm for JavaScript
Digital Signal Processing for Javascript
There are many javascript audio libraries, but most of them make assumptions about using Web Audio API or that audio is being manipulated in real time. Audio-fns takes a different approach, providing functions to generate and operate on audio samples wher
A thin wrapper around the Web Audio API that lets you take some audio and get its waveform/frequency data in return.
utility for managing audio buffers, playback, and visualizations
Convert spectrum, like FFT result, to a color
A simple browser-compatible FFT implementation, with real-valued FFT support
