## What it is
Pyo is a Python module written in C providing classes for a wide variety of audio digital signal processing, usable directly in Python scripts with real-time manipulation via the interpreter. It includes primitives like filters, delays, and synthesis generators, plus advanced algorithms such as sound granulation, with OSC and MIDI support.

## Use cases
- generate and process audio in real time from Python scripts
- build synthesis and effects chains for music production
- create granular sound textures and creative audio manipulations
- control audio parameters via MIDI or OSC
- build sound stimuli for psychology and neuroscience experiments
- prototype DSP algorithms interactively in the Python interpreter

## When to choose
- you need real-time audio DSP embedded in Python
- you want synthesis, filtering, and granulation primitives with OSC/MIDI support
- you're building interactive music or sound art applications in Python

## When to avoid
- you need offline-only audio file editing rather than real-time processing
- you require a non-Python environment or a DAW plugin format
- you need a pure-Python dependency-free solution

## Facets
- artifact type: library
- maturity: stable
- function: audio-processing, sdk
- domain: media, developer-tools
- platform: python, windows, cross-platform
- tags: dsp, synthesis, music, real-time-audio, osc, midi, granular-synthesis, sound-design, audio, macos, linux
