I usually avoid solving that problem. There’s a good workaround — batch items, and either transfer ownership, or implement shared ownership, instead of copy. For an example, look at how multimedia frameworks are designed: Media Foundation, gstreamer, ffmpeg, to lesser extent V4L2 and ASIO. For audio, they often handle samples coming at 48kHz, and they are usually heavily multithreaded, yet they don’t have ring buffers for individual samples, their ring buffers are keeping batches of them.
