How to tune vocals in REAPER for free (with stock ReaTune)
Published July 29, 2026
REAPER already ships with a pitch corrector called ReaTune, so you do not need to buy anything to tune a vocal. Add ReaTune to your vocal track, open the Correction tab, set the Key and scale to match your song (the default is Chromatic, which snaps to the nearest of all twelve notes), and pick a vocal-friendly algorithm such as elastique 2.1 SOLO. Then adjust the attack time so the correction sounds as natural or as tight as you want. ReaTune fixes pitch, not timing or tone, and it works best on one clean, dry voice at a time.
If a home vocal is slightly flat or sharp in places, the take can feel amateur even when the performance and the recording are fine. The good news is that REAPER includes a real pitch-correction plugin, ReaTune, at no extra cost. It is not the most advanced tuner available, but for gentle correction on a single vocal it does the job, and everything below uses only stock plugins.
ReaTune has three modes, selected by the tabs across the top of its window: a Tuner for detecting pitch, an Automatic correction mode, and a Manual correction mode. For tuning a recorded vocal you will use Automatic or Manual. The Tuner tab is really for checking pitch, for example tuning a guitar through your interface.
Before you tune: give ReaTune a clean signal
Pitch correction is only as good as the audio you feed it. ReaTune needs to track one clear pitch at a time, so a little prep makes a big difference.
- Use a dry, mono vocal. Tune the raw lead before you add reverb, delay, or doubles. Effects and bleed confuse pitch detection.
- Tune the lead and any harmonies separately. ReaTune tracks a single voice. A stacked or harmonized part on one track will not correct cleanly.
- Put it early in the chain. Insert ReaTune near the top of the track’s FX chain, before compression and EQ, so it corrects the natural voice rather than a processed one.
Automatic mode, step by step
Automatic mode is the fastest way to hear a result. It listens to the incoming pitch and nudges each note toward the nearest allowed note in real time.
Add ReaTune and open Automatic
Drop ReaTune onto the vocal track’s FX chain and click the Automatic (correction) tab. You will see vertical bars appear as the vocal plays, showing where and how much it is correcting.
Set the key and scale
Choose your song’s Key (A through G#) and a Key mode such as Major or Minor. This matters: the default mode is Chromatic, which snaps to the nearest of all twelve notes and will happily lock a wrong note in place. Telling ReaTune the actual key keeps it musical.
Pick a vocal algorithm
Set the Algorithm to one suited to a single voice. For vocals, elastique 2.1 SOLO (the soloist option) is the usual choice. The other elastique and windowed options exist for different material.
Set the attack, then start subtle
The Attack time controls how quickly ReaTune pulls a note to pitch after it starts. A longer attack sounds more natural because it lets the beginning of each note breathe; a very short attack gives the tight, obvious, machine-locked sound. Start on the slower, more natural side and only shorten it if you actually want that effect.
Most rough ReaTune results come from leaving the mode on Chromatic. In Chromatic, a note that lands halfway between two pitches can get snapped to the wrong one and held there, which sounds worse than the original. Set the real key and scale first, before you touch anything else.
Manual mode, for surgical or natural correction
Automatic mode treats every note the same. Manual mode lets you fix only the notes that need it and leave good notes untouched, which usually sounds more natural. It is slower but more musical.
Switch to Manual and analyze
Click the Manual tab. Enable Track pitch and play the vocal so ReaTune draws the detected pitch as a graph. This shows you exactly where the take drifts flat or sharp.
Draw correction bars only where needed
Click and drag to create a horizontal correction bar over a bad note, then drag it up or down to the right pitch. Adjust the ends of a bar to change where the correction starts and stops. Delete a bar by selecting it and pressing Delete. Correct the obvious misses and leave the rest alone.
Use the safety toggles
If a note jumps a full octave for no reason, enable Prevent octave shifts; that is usually ReaTune misreading a harmonic. Prevent overlapping segments stops correction lines from colliding. Toggle Manual correction off and on to compare before and after.
| Goal | Mode | Starting point | Watch for |
|---|---|---|---|
| Fast, transparent cleanup of a mostly-good take | Automatic | Correct key and scale, longer attack, elastique 2.1 SOLO | Set the key off Chromatic or it snaps wrong notes |
| Only a few notes are off | Manual | Analyze, then draw bars on the bad notes only | Over-correcting good notes and flattening the emotion |
| The tight, obvious tuned effect | Automatic | Very short attack, key locked to the scale | It is a stylistic choice, not a fix for bad singing |
What tuning will not fix
Pitch correction moves notes toward the right pitch. It cannot rescue everything, and expecting too much of it leads to a worse-sounding vocal.
- It will not fix timing. If words land early or late, that is editing, not tuning.
- It will not fix tone problems like muddiness, harshness, or a thin sound. Those are EQ jobs. If the voice is boomy or veiled, see why your home vocal sounds muddy in REAPER; if it sounds weak or small, see how to fix thin vocals in REAPER.
- It struggles with polyphonic or heavily processed audio. Reverb tails, bleed, and stacked harmonies confuse the pitch tracker, which is why you tune the dry, single voice first.
- It cannot replace a committed performance. A note sung with no confidence and wandering pitch can be dragged to the right note, but it will sound obviously corrected. A better take almost always beats heavier tuning.
ReaTune is genuinely useful for gentle correction on a single clean vocal, and it is free. For dense, badly out-of-tune material, or for the most natural-sounding results on a difficult take, dedicated tools like Melodyne handle it more transparently. Start with ReaTune, and only reach for more when the free option clearly is not enough.
If it still sounds off
Quick troubleshooting order when the correction is not landing:
- Wrong or Chromatic key. If notes snap to the wrong pitch, set the correct Key and mode instead of leaving it on Chromatic.
- Artifacts or warbling. If the vocal sounds glitchy, the attack may be too short or the algorithm is not suited to a single voice. Lengthen the attack and confirm you are on a vocal algorithm like
elastique 2.1 SOLO. - It sounds robotic and you did not want that. That is a short attack pulling notes to pitch instantly. Slow the attack down so the start of each note keeps its natural pitch movement.
- ReaTune keeps mistracking. Check the input. Reverb, doubles, or bleed on the track will throw off detection. Tune the dry lead by itself.
REAPER’s stock ReaTune tunes vocals for free. Feed it a dry, mono lead, set the real key and scale so it stops snapping to wrong notes, choose elastique 2.1 SOLO, and start with a slower, natural attack. Use Automatic for quick cleanup and Manual to fix only the notes that need it. Remember it corrects pitch, not timing, tone, or a shaky performance.
Tuned, but the tone still needs work?
Tuning fixes pitch, not EQ and dynamics. Once your vocal is in tune, the free StudioRescue vocal chain sets REAPER’s stock plugins for a cleaner, more balanced tone, so the tuned take actually sits in the mix. Stock plugins only, nothing to buy.
