Q is a cross-platform, header-only C++20 library for audio digital signal processing, built around fine-grained, composable function objects. It includes oscillators, filters, envelopes, dynamics, delays, pitch detection, FFT, granular primitives, and an optional q_io layer for audio and MIDI connectivity.
Use cases
- process audio signals in C++ with composable DSP primitives
- detect pitch in audio streams
- build guitar effects processors
- create synthesizer oscillators and resonant filters
- run DSP on small microcontrollers
- connect to audio and MIDI devices from C++
- implement granular and overlap-add audio effects
When to choose
- you need a lightweight, header-only modern C++ DSP toolkit
- you want efficient audio processing that can run on microcontrollers
- you are building music-related DSP such as synths or guitar effects
- you prefer functional-style composition of reusable DSP building blocks
When to avoid
- you need a full DAW or audio host application rather than a library
- you require a language other than C++
- you need production-grade, heavily battle-tested audio middleware with commercial support
- you want high-level music information retrieval beyond the library's experimental facilities
