Voicemeeter is a powerful virtual audio mixer for Windows that enables users to manage and blend audio from various physical inputs like microphones and digital sources including any application or professional ASIO software. It facilitates combining voice, music, game audio, and DAW outputs such as Cubase or Ableton Live into a single mixed stream, which is ideal for live podcasts, VOIP communications, or recording workflows. By supporting a broad range of audio interfaces including MME, KS, WaveRT, Direct-X, and ASIO, Voicemeeter acts as an audio bridge allowing seamless interaction between different audio drivers and applications.

The mixer supports three input devices and three output devices, both physical and virtual, routed through two main buses, offering extensive routing and mixing options. This setup allows users to handle complex audio scenarios such as mixing multiple USB headsets for online education, combining 5.1 surround sound game audio with microphone input for team communication, or producing professional-quality tutorials and live recordings with multichannel support. Voicemeeter also provides advanced features like stereo mixing, multichannel recording, and customizable audio routing to simplify managing multiple sound sources within a single environment.

Enhancing network audio capabilities, Voicemeeter includes VBAN technology to send and receive multichannel audio streams across local networks using a high-quality UDP protocol. Additionally, the software offers a Remote API and MacroButtons tool that enable users to automate and control mixer functions through custom scripts and shortcuts, supporting complex workflows such as simultaneous muting, gain control, and voice effects. Distributed as donationware, Voicemeeter provides an affordable and flexible solution for both individual users and corporate installations, compatible with all modern Windows versions.
