Steinberg MixKey
What it is
Steinberg MixKey is a free audio mixer for streamers and creators on Windows and macOS. Its Auto Gain feature 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. The built-in low-cut filter reduces unwanted low frequencies in speech. MixKey records the full mix as WAV and can route a separate microphone output to apps such as Discord or Zoom. Panic buttons mute the microphone or cut all output audio instantly. Elgato Stream Deck can trigger functions including mic mute and panic controls. Users can customize channel names, colors, appearance, and interface size. Steinberg lists MixKey as a free Mac and Windows download and says the company was founded in 1984.
