Audio comes in a wide range of formats and types, just like video and images. For a media server operator, knowing your way around the audio jungle is a real plus, potentially saving you time, effort and some sleepless nights. This blog looks at the three major audio categories, and gives media server programmers a hot tip on audio format!
Network audio solutions have been around for many years now, but here’s one that seems to be gaining more traction than most. Dante has been adopted by many vendors who wish to include this kind of interface with their systems, either as fully integrated ones or standalone solutions.
ASIO (Audio Stream Input Output), is a proprietary multi-channel audio interface, developed by Steinberg, which bypasses the operating system's mixing kernel to provide the lowest latency direct communication between the media server and the sound hardware.
WASAPI (Windows Audio Session API) is Microsoft’s multi-channel audio interface for communication with audio devices. WASAPI was introduced with Windows Vista™ and is supported by Windows 7 and later versions. WASAPI delivers an unmodified audio-stream to a sound device, and provides similar benefits as ASIO.
