KQ Voice Plugins app for iPhone and iPad

This is a set of Audio Units including Loopback, Vocoder, Pitch Shifter, and Noise Suppression. A host application that can handle Audio Units is required for use.

Loopback (In/Out/MIDI/Mixer):
Connects to each other and transfers audio between host applications. MIDI signals can also be transferred. Please note that you might not do the recording inter app.

Vocoder:
This effect processes the sound of a synthesizer or other carrier with the input sound (modulator) and outputs it. It creates a so-called robot voice by inputting a voice or other sound.
By default, Saw (sawtooth wave) is specified as the carrier, but it can also be input from a sidechain or Vocoder Input Audio Unit.

Pitch Shifter:
An effect that changes the pitch of the sound.

Noise Suppression:
A noise removal filter using RNNoise. This machine learning filter is optimized for voices.
