MixKey is a game changer for me! I can set my audio outputs clearly and intuitively—whether I want to reliably and easily control what my viewers hear and what they don't, or to implement routing tricks with sound alerts that previously required multiple software programs and training

Sound like a pro. Fast. All-in-one streaming audio mixer software.

Steinberg’s advanced processing automatically manages your levels, so you are ready to go live within minutes, with intelligent Auto Gain and seamless system integration built in.

    No guesswork needed: MixKey sets your levels for you, so you can jump right in without any hassle, using refined Auto Gain technology for consistently balanced sound.

  • Clean recording

    Capture a studio-quality WAV of your full mix — ready to drop, stream, or upload to your favorite streaming platform.

  • Refine your sound: Low-Cut Filter

    Sound clean and professional — no rumble, no boominess, just your voice in crystal-clear quality.

Anything goes in. Everything works out.

Any gear in. Custom feeds out. Total control.

Hardware-agnostic freedom

USB microphones, professional, or prosumer audio gear, ASIO drivers… MixKey is built to work with any streaming software and whatever you already use. Enhanced ASIO performance and optimized WDM exclusivity ensure stable, low-latency operation across setups. No proprietary lock-ins, no complicated setup, and no compatibility issues — just plug in and start streaming.

    Multiple flexible channels

    Whether it’s your mic, guitar, game, browser, or Discord — just drag it in. All your sources come together in one flexible, streamlined interface, where you can mix, balance, and manage everything without distraction. Clearly defined channel types and dedicated app icons on every channel fader keep your setup visually organized and easy to navigate. It’s all in one place and fully under your control.

      Multi-output magic

      Send your mix to OBS, Discord, and your headphones at the same time — each with its own independent volume level. Stay in control of what everyone hears, including fully separated voice chat routing for parallel communication.
