How to loop vocals on iPhone

Record your root note or rhythm first, then sing the harmony over it while it repeats. An iPhone's microphone is genuinely good enough for this — vocals are the one source where a phone needs no extra equipment at all, because your voice is already close to the mic. Layer enough parts and you can harmonise with yourself, build an a cappella arrangement, or loop your voice as the backing for anything else you play.

Why voice is the easiest thing to loop on a phone

Everything that makes phone recording awkward for electric guitar works in your favour here. You can stand close, you control the level by moving your head, and there is no amp in the room competing with you.

Hold the phone about a hand's width away, slightly off-axis so hard consonants do not thump the mic, and sing at a normal volume. Close and quiet beats far and loud every time.

Building a vocal stack

  1. Lay the foundation. A root note, a hummed chord, or a beatbox groove. This sets the loop length.
  2. Add the third, then the fifth. Build the chord upward. Recording them separately is what makes the harmony sound like several people.
  3. Add rhythm. Beatbox, finger clicks, a hand on your chest.
  4. Sing the lead last, over the top of everything.

4 tracks free is enough for a root, a third, a fifth and a lead. 8 with Pro gives you room for percussion and a counter-melody as well.

The three things that make vocal layers muddy

Effects worth using on voice

Jam Looper has per-track reverb, delay, distortion, tremolo, pan, pitch shift, low pass, high pass and resonance. On vocals the useful ones are restraint-based: a little reverb on the lead only, keeping the harmony parts dry so they stay defined, and pitch shift when you want an octave you cannot actually sing.

Hearing yourself while you layer

This is the single biggest difference between vocal layers that lock together and layers that sound approximately right. Sung against a phone speaker, the loop competes with the sound conducted through your own head, and you will consistently sing slightly under the note.

Headphones fix it. Wired headphones fix it best; wireless ones introduce a delay that pushes every new layer late, which is why Jam Looper has a separate Bluetooth latency offset in Settings. There is more detail in using AirPods with a looper app.

Common questions

Can you loop vocals with just an iPhone?

Yes, and voice is the easiest source to loop on a phone — you can sing close to the microphone, so no interface or external mic is needed.

How do you layer harmonies with a looper?

Record the root note first so it sets the loop length, then sing the third and the fifth as separate layers over it. Recording each interval separately is what produces the choral effect.

Why do my vocal loops sound muddy?

Usually all the parts sit in the same octave, or the lowest layer is too loud. Spread the parts across different registers and pull the root down in the mix.

Do I need an external microphone?

No. For layered vocals the built-in microphone is sufficient. A hand's width away and slightly off-axis avoids plosives without needing a pop shield.

Is there an app that lets you harmonise with yourself?

Any vocal looper does this, including Jam Looper. You sing the melody, it repeats, and you sing the harmony over the top. The harmony is sung by you rather than generated — there is no pitch correction or automatic harmoniser involved.

Can you make a cappella music on a phone?

Yes. An a cappella arrangement is bass, chords, percussion and lead, all sung — four parts, which is exactly what four free tracks covers.
