KLANG:app vs STEM

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.

STEM is a free web platform for bands and music collaborators to upload, mix and discuss song stems. Its multi-track mixer handles uploaded stems, while invited members can view or work on projects in real time. Timed comment threads can be attached to individual tracks or the master track. Share links use customizable permissions, allowing songs to remain private or become public. Users can render stems to MP3, save mix snapshots and export renders. Songs can be grouped into playable, shareable lists for albums, EPs, setlists or work sessions, and can carry lyrics, chord charts, reference tracks, session notes and other files. STEM is intended for discussion and shared decisions rather than music creation like a full DAW. Certain features require a Google account. The privacy policy says uploaded audio is accessible to the user and explicitly shared people. The Free plan costs nothing, with limited version history.
