Audio Mixer keeps multitrack playback, recording, overdubbing, routing, and real-time control in one touch-focused workspace. A session can contain up to 15 configurable tracks.

Apply audio effects, edit samples precisely, import or export common audio formats, control the mix through MIDI, and keep recording or performance aligned with the built-in metronome.

I designed Audio Mixer end to end: its product concept, music workflow, information architecture, interaction model, and visual interface. I then implemented the Android experience and took it through testing, release, iteration, and user support.

Audio Mixer is part of the Renetik Music Apps family and shares its Kotlin application foundations, native C++ audio engine, Firebase services, automated tests, and release workflow.
