Single-reader single-writer lock-free ring buffer. PaUtilRingBuffer is a ring buffer used to transport samples between different execution contexts (threads, OS callbacks, interrupt handlers) without requiring the use of any locks. This only works when there is a single reader and a single writer (ie. one thread or callback writes to the ring buffer, another thread or callback reads from it).

Python wrapper for PortAudio's ring buffer - GitHub
https://github.com/spatialaudio/python-pa-ringbuffer
Python wrapper for PortAudio's ring buffer. The ring buffer functionality is typically not included in binary distributions of PortAudio, therefore most Python wrappers don't include it, either.. The pa_ringbuffer module provides only a Python wrapper, the actual PortAudio ring buffer code has to be compiled separately, see Usage.It can be used on any Python …

PortAudio – an Open Source Cross Platform Audio API
https://www.ee.columbia.edu/~mim/meap/paMat/portaudio_v18_1/docs/portaudio_icmc2001.pdf
A variety of sample formats are supported by PortAudio including 16 and 32 bit integer and 32 bit floating point. Where necessary PortAudio manages conversion between the requested buffer formats and those available natively. If requested, PortAudio can clamp out of range samples and/or dither samples to a native format. 3. API Overview
