## What is Formante?

Formante is an AudioUnit AU3 compatible vocal filter plugin.

You can simulate the formants and the vowels of a human voice, creating rich and mellow sounds; it can be applied to synthesizes, drums, guitars or any sound you want.
Its parameters can be controlled by hosts or automated with the integrated drawable envelope (you can choose 16/32/64 steps resolution) and a BPM tempo control.

Its filter engine has been already acclaimed in the vocal section of EGSY01 analogue synth, and we decided to publish it as a standalone filter due to users request.


PLEASE NOTE:
this is not a standalone app, but you need an AU3 compatible host like n-Track, AUM, Auria, Cubasis or Beatmaker3

## Key features

- Simulate human voice formants and vowels
- Apply to synthesizers, drums, guitars, and more
- Control parameters via host or automation
- Integrated drawable envelope with tempo control
- Acclaimed filter engine

### 4/5 — It works but it's unoptimized

*2023-12-15*

It does work as an effect unit in AUM. However, the DSP quickly maxes out and causes poor sound quality from the DSP maxing out. I am able to increase the DSP buffer size to address this. It would nice to see this updated with potential performance improvements (or having more presets or simply having the presets exposed to AUM)

### 2/5 — Meh ?

*2021-10-29*

It's a step sequencer by the way. Not really good for what I want, was hoping for a better formant/pitch shifter than the Vocal Transformer in GB. Kind of just makes it sound irritating honestly, but maybe that's what you want. The choice is yours for just EIGHT dollars.

### 1/5 — Endlessly crashes -

*2021-10-20, version 2.0*

on newest iOS and since a year ago. Idk what else to say. I haven’t used it once.
