Pyroomacoustics is a Python package for audio signal processing in indoor scenarios, combining a fast C++ room acoustics simulator (image source model and ray tracing) with reference implementations of array processing algorithms. It provides an object-oriented interface for simulating sound sources and microphone arrays in 2D/3D rooms and generating room impulse responses.

Use cases

• simulate room impulse responses for a microphone array in a reverberant room
• prototype and benchmark beamforming algorithms
• estimate direction of arrival of sound sources
• generate training data for machine learning audio models
• test adaptive filtering and source separation methods
• simulate acoustic propagation between sources and receivers in 2D and 3D rooms
• denoise single-channel speech recordings

When to choose

• you need to simulate room acoustics or generate room impulse responses quickly
• you are developing or evaluating microphone array processing algorithms like beamforming or DOA estimation
• you want reference Python implementations of STFT, adaptive filtering, or denoising algorithms
• you need synthetic reverberant audio data for research or ML training

When to avoid

• you need real-time audio processing in production systems
• you require physically accurate auralization for professional acoustic engineering or architectural design
• you need full 3D spatial audio rendering for games or VR
• you want a GUI-based acoustic simulation tool rather than a Python library
