Real-Time Pitch Correction Preview
Sing into your microphone and watch, in real time, the note you’re on, the nearest note in your chosen key & scale, and exactly where auto-tune would snap it — with an adjustable correction strength from subtle to hard.
ℹ This is a visualizer: it detects your pitch and shows where correction would move it. It does not alter, auto-tune, or play back your voice — true real-time audio auto-tune needs a low-latency phase-vocoder plug-in. Your microphone is analyzed live on your device and never recorded or uploaded. Use headphones-free; nothing is routed back to your speakers.
How It Works
The tool reads your microphone live and runs a YIN pitch-detection algorithm to find the fundamental frequency you’re singing. It converts that to a musical note, then finds the nearest note that belongs to the key and scale you picked (for example, in C major it will ignore the black keys). The correction strength slider shows how far auto-tune would pull your pitch toward that scale note — 0% leaves it alone, 100% snaps it exactly onto the note. The ribbon visualizes your actual pitch, the target note, and the corrected position between them.
Everything happens on your device; nothing is recorded or uploaded. Importantly, this visualizes correction — it does not produce auto-tuned audio. Real-time audio auto-tune requires a low-latency phase-vocoder running in an audio plug-in or DAW. Use this to train your ear and check pitch accuracy against a scale, or to understand what an auto-tune effect is doing.
