tunelet is an open-source library for vocal pitch correction, choir, harmony, formant control and effects. It runs natively in Rust, and in browsers and Node.js through WebAssembly. Fixed-point DSP gives the same output samples on every run, and the audio calls never allocate memory, so it fits real-time audio threads.

Could you build this?
Partial Pitch correction, harmony, and formant effects can be prototyped with AI help and existing DSP references. Achieving production quality and real-time, allocation-free behavior requires real DSP expertise.
What it would actually take: The architecture is a Rust core with a WebAssembly build, using a fixed-point or deterministic pitch detector, a pitch-shifting method such as PSOLA or a phase vocoder, and formant-preserving resynthesis. The hard parts are artifact-free pitch shifting, low-latency real-time processing, and formant control, which take signal-processing knowledge and extensive listening tests to get right.
