## What is Harmonize Vocal Tuner?

Harmonize is a simple audio workstation that lets you autotune your voice wherever, whenever, and however you want.

Many apps claim to have autotune functionality, but do nothing but apply a robotic-sounding filter to your voice. With Harmonize, you get real autotune. Using algorithms I produced as a part of my master's thesis, Harmonize truly detects the pitch of your voice, adjusts it over time, and resynthesizes it into a new waveform that's perfectly in tune.

Harmonize gives you full control over the pitch of your voice with a comprehensive set of pitch manipulation tools. You can keep things simple and autotune to a preset scale, or you can manually set what pitches to tune your voice to at every point in time. You can fine tune how your autotune is applied; you can add chorus and vibrato to your voice; you can even layer multiple tuned copies of your voice to create expressive chords and harmonies. With Harmonize, these tools are all yours.

HIGH-QUALITY RECORDING
Record your voice straight into the app. No special equipment required.

AUTOTUNING MADE EASY
Autotune your voice in two taps. Adjust the autotune settings, such as the key and attack time, with a simple and intuitive UI.

COMPLETE CONTROL OVER YOUR VOICE
If the autotuning isn't enough, choose exactly how to tune your voice with Manual Tuning. Choose the pitches you want to tune to, place them on the timeline, and hit Generate. Add multiple Manual Tuning tracks to create entire choirs from one recording!

RESULTS IN SECONDS
Harmonize uses a self-made autotune algorithm with extensive optimization and parallelization to tune any recording in no time. Most recordings take less than a second.

### 3/5 — some interesting observations

*2024-05-12*

I'd downloaded this app out of curiosity, but noticed some strange quirks. Note, I'm using voiceover, so this may have something to do with it but firstly, my phone slows to an absolute crawl inside of projects. It's to the point where I can't even have audio playing while moving around the screen. 
Additionally, I'd tried the auto-tune on an imported file and it sounded as though it had been sped up a ton. 
Is this just me, or is this a known bug?
If these issues could be fixed, I'll adjust my star rating.

### 5/5 — Great App!!!

*2023-12-31*

I thoroughly enjoy using this app!!! :) Love the user experience, features & affordable to upgrade from the free trial!
