Start the mic, then choose your speakers or headphones here.

Can’t find your speakers?
  1. Stop the mic here first.
  2. Open System Settings → Sound → Output.
  3. Choose MacBook Air Speakers, your desktop speakers, or wired headphones, and turn the volume down.
  4. Return here, restart the mic, then confirm the route before selecting Hear my voice.

For this test, keep AirPods selected as the microphone and choose the computer speakers as output. The two selections are independent. Apple’s output guide ↗

Hear yourself

Muted

Output muted

Start quietly. Pause other song tabs; keep the mic away from speakers. Wired headphones are the safer first test. Hardware volume still matters.

Make it yours

Start with a sound. Fine-tune only if you want to.

Neon Lock

Hard-tuned notes. Your own voice.

Finish one measured performance to unlock.

Locked · 100%

Above Locked adds a note-locked electronic voice. Move it while singing or previewing.

Hear the difference

A short synth voice · no microphone needed.

Reverb adds space to your voice. It cannot remove Bluetooth delay.

18%
Fine-tune the dry voice Original vocal balance
65%

Sets the unaffected voice mixed with your reverb. “Reverb only” sets this to zero.

Pitch assist Experimental · off by default
Pitch correction settings
70%
80 ms
Voice Scale target Off

Off. Reverb does not wait for pitch detection.

Not the song’s melody, not formant-preserving, and no effect on scoring. Use one clear voice at a time.

Advanced audio & diagnostics Speaker bleed, device processing and latency

AirPods input + computer speakers avoids a wireless return to your ears, but wireless input can still be late. Compare the Mac mic, a wired/USB mic, or an iPhone using Continuity.

All effects run locally. No audio upload, recording, camera or AI model download. Leaving this tab or changing devices stops the mic; it never restarts itself.

ROUTE DIAGNOSTICS

Sample rate
Input latency · reported
Browser processing · reported
Output latency · estimated

These are partial browser estimates, not measured mouth-to-speaker delay. We don’t add them into a misleading total.

Compare your setups Optional listening notes · this tab only

Say “one, two”, then sustain a vowel. Try dry voice, reverb, then pitch assist. These notes are subjective, not a latency measurement; no audio is saved.
