The Complete Guide to Voice Changer Apps for Mac

Complete Guide to Mac-Compatible Voice Changer Apps Even a Rabbit Can Understand

Hello! In this article, I will thoroughly explain voice changer apps compatible with Mac. Voice changers are active in various scenes such as streaming, video conferencing, and creative activities. I'll introduce recommended tools ranging from commercial apps to open source.

"I want to change this rabbit's voice a little, pyon..." There are many apps now that can make such wishes come true!

Basics and Mechanism of Voice Changers

A voice changer is a tool that converts input audio into a different voice quality. It can be broadly divided into two types: "Traditional" and "AI-based."

Traditional Voice Changers

Traditional voice changers change the voice mainly by adjusting the following parameters:

• Pitch Change: Adjust the height of the voice up or down
• Formant Adjustment: Change the voice quality by altering the characteristics of the vocal tract
• Effect Addition: Add effects such as echo and reverb

By combining these parameters, you can create robot voices or voices of the opposite sex. However, there are limits to naturalness, and a characteristic mechanical impression tends to remain.

AI-based Voice Changers

AI-based voice changers have been developing rapidly in recent years. They use deep learning technology to perform conversions based on features learned from large amounts of voice data.

Input Audio → Feature Extraction → AI Processing → Voice Reconstruction → Output Audio

The features of AI voice changers are as follows:

• High Naturalness: Naturally reproduces the voice of a specific person or character
• Learning Possible with Small Samples: Captures features with just a few seconds to a few minutes of audio
• High Computational Cost: A high-performance processing environment may be required

In particular, with the latest technologies such as RVC (Retrieval-based Voice Conversion), it is now possible to learn the target voice from a voice sample of only about 10 seconds.

Difference Between Real-time Processing and Post-recording Processing

There are two usage patterns for voice changers: real-time processing and post-recording processing.

Real-time Processing:

• Immediate conversion for online meetings, game streaming, etc.
• Low latency is important (ideally 0.1 seconds or less)
• Balance with processing load is necessary

Post-recording Processing:

• Applied to video editing and audio content creation
• High-quality conversion is possible
• Fewer time constraints
