KLANG:app vs Steinberg MixKey

KLANG:app is the control interface for KLANG processors, bringing setup, mixing and signal placement into one app. Each musician can adjust an individual sound mix. Users can position instruments around the listening space, including above or below the listener’s head, or use conventional stereo. Mixing tools include faders, panning, system settings and graphical 3D and i3D orbits. The app connects to processors over Wi-Fi or LAN and can manage one mix per device or all mixes from a single app. An offline editor and demo mode are included. Console integrations cover DiGiCo SD and Quantum, including mix-parameter control and snapshot recall, and SSL Live, with two-way control of faders, panning, mute, solo and tone filters. It also communicates using Open Sound Control and supports MIDI MCU and MIDI for Allen & Heath consoles. KLANG:app is free for supported devices, with no free trial, and runs on Android, iOS, macOS and Windows.

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.
