StudioWavePro’s Autotune listens to your clip, finds its dominant pitch, and shifts it to the nearest note in the key and scale you pick: major, minor, pentatonic or chromatic, on any of the 12 root notes. The panel shows the detected root and the exact shift applied, so you can see what changed instead of guessing.

The correction is one pitch shift for the whole clip, with the tempo unchanged. That makes it ideal for a sung phrase, a held note, a sample or a single instrument line that sits slightly sharp or flat. It is not a per-note, robotic hard tune — for a long performance that moves between notes, split it into phrases first and tune each one.

When to use Autotune

A sung phrase or held note that sits a little sharp or flat against the backing track.
Using autotune on a vocal sample or one-shot so it matches the key of your beat.
Matching an instrument recording (guitar, flute, hum) to a song’s key.
Fixing a voice-memo melody before sending it to a producer.
Checking which note a recording centres on — the detected root shows before you apply anything.

How to use Autotune

Click "Upload audio" below and drop in an MP3, WAV, OGG, M4A or FLAC file.
Pick the Target key (C to B) and a Scale — Major, Minor, Pentatonic or Chromatic — or start from a preset such as Subtle correction.
Set Strength: 100% snaps fully to the nearest scale note, lower values apply part of the correction.
Press "Play preview" to hear the first 10 seconds, then click "Apply Autotune" and download as WAV or MP3.

Tips for best results

Run the Song Key Finder first if you don’t know the key, then set the same key here.
Chromatic snaps to the nearest semitone of any kind — the safest choice when you only want the take in tune, not in a particular key.
Work phrase by phrase. The autotune applies one correction per file, so trim the clip to a single phrase or held note first (Audio Trimmer or Audio Splitter).
Keep Strength around 40–60% for a natural result on a take that is only slightly off.
To move a track by a set number of semitones on purpose, use the Pitch Changer instead.

Frequently asked questions

How do I autotune my voice online for free?: Upload your recording (ideally one phrase), choose the song’s key and scale, and press Play preview. If it sounds right, click Apply Autotune and download the result as MP3 or WAV. No signup or install is needed.
Does it create the hard-tune robot effect?: No. That effect snaps every note to the scale many times per second. This tool detects the overall pitch of the clip and applies one correction to all of it, which suits a phrase or held note that is slightly off but does not create the robotic stepping sound.
Which key should I choose?: Use the key of the song your vocal sits on. If you don’t know it, run the track through the Song Key Finder. If you only want the take in tune, choose Chromatic.
What does Strength do?: It scales the correction. At 100% the pitch moves all the way to the nearest scale note; at 50% it moves halfway. Lower values keep more of the original performance.
Does autotune change the speed of my audio?: No. The pitch shift keeps the original tempo and length, so the corrected clip stays in time with your backing track.
Can I autotune a whole song?: You can, but a full song moves through many notes, so one overall correction rarely helps. Split the vocal into phrases with the Audio Splitter, tune each one, then rejoin them with the Audio Merger.
