/**
* @brief The MprAudioFrameBuffer resource buffers frames of audio that
* pass through to be retrieved later.
*
* This resource always passes input 0 through to output 0, but it keeps a
* reference of the buffer passed through for a configured length of time
* (frame periods). No latency is added to the input. References are just
* kept for the input buffers which can be accessed via the getFrame method.
