Note2Input
by Spelis
Note2Input lets players control Minecraft with sound from a microphone or a musical instrument, mapping detected pitches to in-game inputs.
What it does
The mod listens to a microphone in real time and analyzes the pitch of what it hears. Each pitch can be bound to a key mapping, so a played note triggers an action in the game. Players set up their own pitch key mappings, choose which input device is read, and pick where output feedback goes.
Signal gain and a master toggle let players tune how sensitive the detection is and switch the feature off when it is not wanted. The author recommends a dedicated audio interface over a plain microphone; a bass guitar plugged into an interface was used during development. Note2Input is client-side only, so only the player's game needs it. It is open source under the MIT License and requires Fabric API on Fabric. Files are published for 1.21.11 and 26.2, with version 1.1 for 26.2 as the latest file, dated 2026-07-09.
Key features
Real-time pitch detection
The microphone signal is analyzed continuously, and the detected pitch is available for key mapping.
Custom pitch key mappings
Each pitch can be assigned to a key, so notes played on an instrument act as keyboard presses.
Input and output gates
Separate selection gates choose the input source and the output feedback destination.
Signal gain and master toggle
Gain adjusts how strong the incoming signal is, and a master toggle turns the whole feature on or off.

Who it’s for: Musicians and players who want to try controlling the game with sound. The author suggests an interface-based setup for the most dependable input.
