Closed-back headphones and IEMs block your own voice — the occlusion effect. Without natural air and bone conduction feedback, your brain loses track of how you sound. You unconsciously speak louder, mumble, or lose control of your vocal tone. This is especially noticeable during long sessions with noise-isolating headphones.
Sidetone fixes this by routing your mic back to your headphones with near-zero latency, restoring the feedback loop your brain expects. Many gaming headsets have this built in — Vibetone brings it to any mic + headphone combo.

Latency depends on your buffer size and sample rate — tune it to your hardware:
| Buffer | 44.1 kHz | 48 kHz | 96 kHz |
|---|---|---|---|
| 16 | 0.4ms | 0.3ms | 0.2ms |
| 32 | 0.7ms | 0.7ms | 0.3ms |
| 64 | 1.5ms | 1.3ms | 0.7ms |
| 128 | 2.9ms | 2.7ms | 1.3ms |
| 256 | 5.8ms | 5.3ms | 2.7ms |
| 512 | 11.6ms | 10.7ms | 5.3ms |
| 1024 | 23.2ms | 21.3ms | 10.7ms |
Smaller buffer = lower latency but more CPU demand. Anything under ~10ms is imperceptible.
Requires Rust.
