About This Game

Build a signal. Hear it work.

Wire a sine into a delay and you have an echo. Push a filter's Q and hear it ring. Build a vocoder and make a carrier tone speak.

In DSP Bench, a live signal engine runs your patch sample by sample. Each puzzle gives you a job to do and checks the result against real measurements: pitch, level, distortion, latency and aliasing. If the output sounds wrong, drop in a probe and follow the signal.

66 puzzles, from one sample to a vocoder

Work through nine chapters as you build:

• Signals and sampling: sample rate, aliasing, bits and dither.
  
• Time-domain tools: levels, mixing, delay, echo and comb filters.
  
• Filters: one-pole, biquad, EQ and FIR design.
  
• Frequency domain: leakage, windows and spectrograms.
  
• Modulation and effects: tremolo, ring modulation, chorus, phaser, distortion and a pedal board.
  
• Dynamics: compressors, gates and limiters.
  
• Synthesis: envelopes, FM and a plucked Karplus-Strong string.
  
• Estimation and adaptive: pitch detection, noise and echo cancelling.
  
• Capstones: a vocoder and an AM radio inside the box.

Learn as you build

Every exercise includes a brief, a deeper lesson and hints you can reveal one at a time. Look up unfamiliar terms in the glossary, and revisit the formulas in each chapter recap.

See it and hear it

Put Probe blocks on your patch and watch the signals on the live scope, then open the Spectrum and Spectrogram tabs to see where the energy goes. Press Listen to hear your Output, or step through one sample at a time to see exactly what each block does.

Keep experimenting

Start from a blank board or one of thirteen starter patches in the sandbox, including a pedal board, an FM bell, a vocoder and a Karplus guitar. Save your patches, copy them as text or export a picture.

Undo, restart and autosave keep experimentation comfortable. Adjust the interface scale, color palette, sound and visual effects to suit your bench.

Single player. English interface. Play offline on Windows and macOS; no additional game account required.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

AI assistants helped write and edit the game's source code, teaching text and store copy, and helped prepare the code that draws its procedural promotional graphics. DSP Bench does not generate AI content during play. Its signal engine runs locally.
