SimVX Audio Miniaudio

SimVX's native audio: miniaudio mixes, spatialises and runs the bus effects in C on its own thread. Most users want simvx, which includes it where a wheel exists.

Pre-alpha. SimVX publishes development releases only (0.0.0.devN) and is under active development; the API changes between builds. Once stable versions ship to PyPI, development builds continue on pypi.simvx.com.

Install

pip install --pre simvx

Latest development build: add --extra-index-url https://pypi.simvx.com/.

Use

Nothing to configure: when installed it is used, and AudioPlayer, AudioPlayer2D and AudioPlayer3D play through it. Without it, desktop audio runs on core's Python mixer, at higher latency and without bus effects, and the log says so once.

What it adds:

• Mixing, 3D spatialisation and Doppler in native code, unaffected by the GIL.
• Every bus effect: gain, biquad filters, parametric EQ, delay, reverb, soft clip and compressor.
• Streaming of Ogg Vorbis, MP3 and FLAC decoded in C.

Platforms: wheels for Linux x86_64 and aarch64 and Windows x86_64; only Linux x86_64 is tested. There is no macOS build, so macOS uses the Python mixer. The library is loaded through cffi's ABI mode and the wheel is tagged py3-none-<platform>, so one wheel per platform serves every CPython 3.14 build, free-threaded included.
