Versions:
obs-asio 3.2.0, developed by Andersama & pkv, is a lightweight ASIO driver extension that integrates low-latency, multichannel audio hardware directly into OBS Studio. Designed for broadcasters, musicians, and podcast producers who rely on professional sound cards, the plugin exposes every input and output channel offered by the ASIO device as an independent OBS audio source, eliminating the need for loopback cables or virtual cables and preserving the bit-perfect signal path demanded by high-resolution recordings. Typical deployments include streaming live band performances with individual drum, vocal, and instrument channels mixed in real time, capturing multi-channel gaming commentary while keeping microphone and chat audio separate, and routing DAW outputs straight to OBS for tutorial or reaction content without introducing Windows audio stack latency. The project has iterated through three public releases, each refining stability, sample-rate switching, and buffer management to accommodate both entry-level USB interfaces and high-channel-count PCIe cards. Because the module follows OBS’s native plugin architecture, installation is a single-file drop into the obs-plugins folder; once loaded, the ASIO source appears alongside standard microphone and desktop audio entries, letting users assign custom names, channel mappings, and filters per source. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
