Pitch

Change pitch while preserving playback duration.

Visual walkthrough2 configuration controlsSynced audio walkthrough

The processor adds algorithmic latency. Speech can acquire artifacts; changing pitch is not formant preservation or voice identity conversion.

01 / Understand

The idea, before the settings.

Semitones are musical steps: 12 makes an octave. Cents provide fine tuning: 100 cents make a semitone. Both controls combine.

Voice / instrumentPitchOutput

Use it in AudioRouter

  1. Begin at 0 Semitones and 0 Cents.
  2. Try a small shift such as −2 semitones, then listen through a whole phrase.
  3. Use Cents for fine adjustment. Check clarity and latency before using a large interval.

What success looks like

Musical pitch changes while the phrase duration remains the same; +12 semitones is one octave.

If it does not work

If intelligibility suffers, reduce the shift and compare the unprocessed source. Large shifts can expose artifacts.

Select the node to open Properties. Click its name to rename it. While playing, supported parameter-only edits save after a short pause. For structural edits, use Save when the canvas marks a change. Enabled and Bypass are distinct live controls; see the in-app help for their behavior.

02 / Explore

Make the behavior visible.

A synthesized bell melody is regenerated at the new pitch with exactly the original note timing. This teaches interval and timing, not the engine's pitch-shifting artifacts.

The example repeats until you press Stop, and control changes are heard immediately. The picture shows the tool's shape rather than time; follow the timing in Follow the sound below. This is not a DSP measurement or control for your running AudioRouter session.

03 / Configure

Every control, with a reason.

Semitones

semitones

Coarse musical pitch offset.

Range / choices-12 semitones → 12 semitonesDefault0 semitones

↓ Lower / alternativeLowers pitch.

↑ Higher / alternativeRaises pitch.

Try this+12 is one octave up; −12 is one octave down.

Keep in mind Does not provide optional future formant control.

02

Fine pitch offset added to Semitones.

↓ Lower / alternativeLowers pitch slightly.

↑ Higher / alternativeRaises pitch slightly.

Try this+50 cents is half a semitone.

Keep in mind 100 cents equal one semitone.

04 / Put it to work

Start with a useful example.

Example 1

Try a subtle character voice

  1. Start at −2 semitones and 0 cents.
  2. Listen to a complete sentence, including sibilants.
  3. Compare latency and clarity before making a larger shift.
Example 2

Fine-tune a steady source

  1. Leave semitones at 0.
  2. Try +10 cents for a small upward adjustment.
  3. Evaluate after the processor has warmed up.

These are starting points. Compare at a comfortable monitoring level and adjust for your own source.

05 / Get unstuck

Small details that matter.

  • A pitch shift does not change the duration setting of a file.
  • Large shifts can affect speech intelligibility.
