Steinberg MixKey is a free audio mixer for streamers and creators on Windows and macOS. Auto Gain adjusts levels automatically, while stream-level monitoring lets users hear the mix as the audience hears it. A cue function previews a channel in headphones before it reaches the fader or mix, and a built-in low-cut filter reduces unwanted low frequencies in speech. MixKey records the full mix as a WAV file and can send a separate microphone output to applications such as Discord or Zoom. Panic controls can mute the microphone or cut all output instantly. Elgato Stream Deck can trigger functions including microphone mute and panic controls. Users can rename channels, change colors and appearance, and resize the interface. Steinberg lists MixKey as a free download for Mac and Windows. The software supports live audio input and WAV export, with no paid plan listed.
