Questions tagged [asio]

ASIO stands for Audio Stream Input/Output, a digital audio protocol. For questions about the Boost.Asio C++ library for asynchronous I/O, use the [boost-asio] tag to avoid ambiguity.

Audio Stream Input/Output is a low-latency protocol for sending and receiving audio data from sound interfaces. It was developed by Steinberg, which offers a licensed ASIO SDK among other audio software technology such as VST plugins.

Please note that in order to avoid ambiguity, questions about Boost.Asio should be tagged with as discussed on meta.
