What Steinberg MixKey is
Steinberg MixKey is a free audio mixer for streamers and creators on Windows and macOS. Its Auto Gain feature adjusts audio levels automatically, and users can link monitoring to stream levels to hear the mix as the audience hears it. A cue function lets users listen to a channel in headphones before it reaches the fader or mix. The built-in low-cut filter is intended to reduce unwanted low frequencies in speech. MixKey can record the full mix as WAV and route a separate microphone output to apps such as Discord or Zoom. Panic controls can mute the microphone or cut all output audio instantly. Essential functions, including mic mute and panic controls, can also be triggered from Elgato Stream Deck. Users can change channel names, colors, and appearance, and resize the interface. Steinberg lists MixKey as a free download for Mac and Windows; the plan is listed as free. Steinberg says it was founded in 1984.
