GUIDE / autotune online
What does autotune do?
Online autotune detects the fundamental pitch of a monophonic vocal and moves voiced notes toward allowed notes in a selected scale. SoundTools performs that analysis and correction inside a browser worker, leaves unvoiced frames alone, preserves the timeline, and creates a local WAV you can compare before downloading.

FIELD NOTES / 01
A real local processor, not a decorative upload box
YIN pitch detection + local granular DSP runs after you choose a source and explicitly start the operation. The audio samples remain in browser memory; SoundTools does not send the selected media to an application endpoint.
Choose a root and scale, then balance correction strength, retune speed, and humanize before processing the uploaded vocal. Results remain available for preview and download only in the current tab. Closing or refreshing the page releases those temporary objects.
PROCESS / THREE STEPS
How to use autotune
- 01
Choose the local source
Open a compatible file in the dedicated workbench at the top of this page. The browser validates and decodes it without an upload step.
- 02
Set the useful controls
Choose a root and scale, then balance correction strength, retune speed, and humanize before processing the uploaded vocal.
- 03
Process, check, and export
Run the local processor, inspect the status and preview, then save Pitch-corrected WAV when the result is ready.

What this tool actually does
Clear limits are part of a useful tool. These values describe the processor currently running in this page.
Runtime and model assets may be downloaded, but the selected file is not attached to those requests.
The dedicated workbench exposes only formats it can actually produce in the current browser.
USE CASES / 02
Useful reasons to open autotune
- Vocal demo cleanup
Move a mostly in-tune solo take closer to the intended scale.
- Hard-tuned character
Use strong, fast correction for an intentionally obvious note-snapping effect.
- Private practice check
Compare an original line with its corrected local render.
QUESTIONS / PRACTICAL ANSWERS
Questions about this tool
Answers based on the current browser processor—not promises about a future version.
01Is my audio uploaded for processing?
No. Audio samples stay in browser memory. The page may download a codec or model asset, but it does not send the selected file with that request.
02Why can the first run take longer?
This tool uses YIN pitch detection + local granular DSP. A browser may need to download and initialize that runtime before the first operation; later runs can reuse cached assets.
03Can I preview the result before saving?
Yes. Audio-producing tools expose local result players, while analysis and transcription tools show their detected data before download.
04What happens when the browser is unsupported?
The workbench reports the missing capability instead of uploading the media or pretending that processing is still running.
05Does this autotune work with a live microphone?
No. This version processes an uploaded recording offline so it can analyze and render the complete file locally.
06Can autotune fix a full song or harmony?
It is designed for one dominant vocal melody. Chords, backing vocals, instruments, heavy noise, and reverb can confuse pitch detection.
