Pitch Shifter
by iBreakerMOD
Pitch Shifter, a client-side Fabric mod, changes the pitch and formant of a player's voice in real time while they talk through Simple Voice Chat.
What it does
Once the Simple Voice Chat voice changer is active, the mod transforms the speaker's voice inside Minecraft, so the effect reaches other players in the voice channel. It uses an SMB Phase Vocoder, a pitch shifting algorithm described by its author as industry standard with minimal artifacts, and the reported latency is 42 ms. Pitch and formant can be lowered or raised to make a voice deeper or higher, and grit intensity and reverb are adjustable as well.
The mod is built around Simple Voice Chat, which must be installed for it to work. Its add-on, Pitch Shifter Addon, is listed by the author as a companion, and effect presets can be stored in files for later use. Pitch Shifter is released under All rights reserved and is not open source. Files exist for 26.3 and the eleven versions 1.21.6 – 26.3, with the latest Fabric file dated 2026-09-24.
Key features
Real-time pitch shifting
Pitch can be scaled down or up by a factor of 0.5, changing how deep or high the voice sounds while speaking.
Reverb settings
Reverb amount and decay can both be set, giving a room-like tail to the processed voice.
Presets and grit
Grit intensity adds rougher texture, and effect settings can be saved as preset files and loaded again.

Who it’s for: Players who use Simple Voice Chat and want to alter their own voice inside Minecraft. Only the client runs the mod, so server owners do not need to install it.
