DSP.js is a JavaScript digital signal processing library providing FFT/DFT transforms, oscillators, window functions, ADSR envelopes, IIR filters, delay, and reverb. It is explicitly unmaintained and has been for years.

Use cases

• compute FFT of an audio signal in JavaScript
• generate sine, square, saw, or triangle waveforms in the browser
• apply lowpass or highpass IIR filters to a signal
• add reverb or delay effects to audio buffers
• analyze frequency spectrum of a signal
• apply ADSR envelopes to synthesized audio

When to choose

• you need a small, dependency-free DSP toolkit for browser or Node.js
• you want simple FFT/DFT and oscillator primitives for audio experiments
• you're okay maintaining a fork yourself since the code is stable and MIT-licensed

When to avoid

• you need an actively maintained library with bug fixes and security updates
• you need high-performance DSP - consider native or WASM-based alternatives
• you need advanced features like multichannel processing or modern filter designs
