Pitch correction, with Raèld Key · Version 1.0 · Product page

About Raèld Tune

Raèld Tune puts a voice in tune two ways. Auto corrects it as it plays, from a gentle natural polish to the classic hard-tune effect. Graph lets you capture a take and see every note on a piano roll, then move, snap or steady them one by one. Raèld Key comes with it: put it on your instrumental and it finds the key and tuning and sends them to Raèld Tune for you.

Installing

  1. Close your DAW.
  2. Unzip Raeld-Tune-1.0.0-Windows.zip from the download page or your purchase email, run Raeld-Tune-Setup.exe and follow the steps. One installer puts both plugins into C:\Program Files\Common Files\VST3, with standalone apps too.
  3. Open your DAW and rescan plugins. DAW plugin lists show them without the accent, as "Raeld Tune" and "Raeld Key", so type "raeld" in the plugin browser.

Requirements: Windows 10 or 11 (64-bit) and any VST3 host, or the standalone apps.

Quick start

  1. Put Raèld Key on the instrumental (the beat, a loop, the band bus). Play the song: it shows the key, for example A MINOR.
  2. Put Raèld Tune on the vocal. With KEY LINK on (it is by default) it picks up the key and tuning from Raèld Key by itself.
  3. Choose the VOICE range and turn RETUNE SPEED: around 20–60 ms for natural pop, 0 ms for the hard-tune effect.
  4. For hands-on editing, switch to GRAPH, press CAPTURE, play the vocal, stop, and edit the notes.

Auto mode

ControlWhat it does
KEY / SCALEThe notes the voice is pulled to: 13 scales including major, minor, harmonic and melodic minor, pentatonics, blues and the modes. Chromatic uses every semitone.
NOTESA keyboard showing the notes in use. Click a lit note to take it out of the scale (the voice won't land there), click again to put it back.
VOICEThe singer's range: Soprano, Alto / Tenor, Low Male, Instrument. Lower ranges need a longer look-ahead to hear the pitch; your DAW compensates for it. At 48 kHz the latency is 26, 39, 54 and 66 ms.
RETUNE SPEEDHow fast notes are pulled into tune: 0 ms jumps instantly (the hard-tune effect); higher settings let scoops and vibrato through.
HUMANIZESlows the retune on long notes so they stay natural, while short notes stay tight.
FLEXOnly corrects notes that are already close. Big slides and expressive bends are left alone.
VIBRATOThe singer's own vibrato: −100% removes it, +100% doubles it (or brings it back with hard tune).
FORMANTThe character of the voice. Natural keeps it as sung while the pitch moves. Turn it down for a deeper, bigger voice, up for a brighter, younger one.
TRANSPOSEMoves the whole voice up or down in semitones.
REFERENCEConcert pitch, where A sits (440 Hz is standard). Raèld Key measures it, so a track tuned to 432 Hz is corrected to 432.
MIXCorrected against original.
KEY LINKFollow the key Raèld Key hears on the same channel letter (A to D). If you change the key here, your choice sticks until Raèld Key hears a different key.

The PITCH display shows what's sung (grey) and what comes out (bright) over the notes of the scale, the note being aimed at and how many cents off the singer was. The meter turns from red to the accent colour when they're within 10 cents.

Graph mode: edit every note

  1. Press CAPTURE (its light comes on).
  2. Play the vocal in your DAW. Capture any part of the song, as much as you like.
  3. Stop the song. The notes appear on the piano roll: each block is a note, the line inside it is the pitch as sung.
To...Do this
Move a noteDrag it up or down. It moves in semitones; hold Alt to move it freely.
Snap a note into the keyDouble-click it.
Fix the whole takeSNAP ALL puts every note on the nearest note of the key. STRAIGHTEN ALL steadies them (80%, keeping some life).
Select several notesDrag across empty space, or Shift-click. Ctrl+A selects all. The buttons then work on just those.
Fine-tune selected notesThe NOTE panel: FINE (cents), STRAIGHTEN (flattens the drift), VIBRATO (0–200%), GAIN (±12 dB).
Start overRESET ALL (or Delete on selected notes) puts them back as sung. UNDO / REDO (Ctrl+Z / Ctrl+Y).
Find your wayScroll to move along the song, Ctrl+scroll to zoom, Shift+scroll to move up and down. FOLLOW keeps the playhead in view.

Notes are found the way you'd hear them: a slide belongs to the note it leads into and is cut halfway, a wide vibrato stays one note, and a step of a semitone makes a new note. The take is saved next to your presets (Documents\Raeld Audio\Raeld Tune\Takes) and your edits are saved with the DAW session, so they come back when you reopen the project.

Graph mode works on one voice at a time: vocals, solo instruments and single-note samples. Chords (a guitar, a piano) can't be split into separate notes here.

Raèld Key

Raèld Key listens to the instrumental (the audio passes through untouched) and shows its key, the runner-up (usually the relative major or minor), how sure it is, and the tuning (where A sits, in Hz and cents). The wheel shows how much of each note it heard, round the circle of fifths.

ControlWhat it does
SONG / LIVESong learns from everything since you pressed play (the steadiest answer for a whole track). Live follows only the last 20 seconds, for songs that change key.
LISTENLearn from what plays. Turn it off to hold the answer.
RESETForget what was heard and start again, for example for the next song.
SENDSend the key and tuning to every Raèld Tune with KEY LINK on the same channel letter (A to D). Use different letters for different songs in one session.

Mono and stereo

Raèld Tune and Raèld Key run on mono, mono-to-stereo and stereo tracks; your DAW picks automatically. On a mono-to-stereo track the mono source feeds both sides. The MONO switch in the preset strip folds the output to mono, to check how a mix holds up on a mono speaker. It's click-free, works while bypassed, and isn't saved in presets. The bottom bar shows how it's running: MONO, STEREO or MONO > STEREO.

Activation and support

Paste your Raèld Tune license key, or your Raèld All Access key, into the activation window. One key unlocks both Raèld Tune and Raèld Key, on up to 3 computers. Without a key the plugins run as a demo with a short dropout every 45 seconds. See support, or email info@raeldaudio.com.
