# RingBuffer It is a way to connect the SDF graph to an audio source or sink. The node part is implemented in the AudioSource and AudioSink parts. The main implementation is in `RingBuffer`. To port it to new environments: - A file RingPrivate.h must be written. It is included by RingBuffer.cpp to customize some part of the implementation - A file managing the audio interrupts must be written an interact with the Ring buffers - The file RingConfig.h must be provided to size the buffers - Most of the time the Ring buffer will have only 2 buffers and will be a ping-pong buffer.
