Essential Tools for Human Voice Delineation and Noise Removal

Is there any hardware or software that can distinguish human voice and filter out surrounding noise? If not, how do you write one? This article delves into the available tools and discusses the feasibility of crafting your own solution.

Existing Software Solutions

Yes, many plugins and software applications are designed to handle voice isolation and noise reduction. Popular choices include iZotope RX6 and Waves NS1

iZotope RX6 Advanced

iZotope RX6 Advanced boasts a feature called Dialogue Isolate, which utilizes AI and machine learning technologies. This module separates human voice from background noise, allowing you to isolate, remove, or adjust the mix to your preference.

Audacity as a Free Alternative

For users on a budget, Audacity, a free and open-source audio editing software, offers basic voice isolation and noise reduction functionalities. While it may not provide the same level of sophistication as professional-grade plugins, it serves well for amateur projects.

Broadcast Editing Software

Clients seeking more advanced features can invest in dedicated broadcast editing software like Waves' Broadcast Suite, which is specifically designed to eliminate unwanted noise from recordings. These tools provide a comprehensive suite of features that cater to professional audio engineers and broadcasters.

Challenges in Developing Custom Software

Creating a tool to distinguish human voice and filter out surrounding noise is not a trivial task. It requires a solid understanding of sound engineering, signal processing, and machine learning. Specialists in this field often rely on advanced algorithms and training data to achieve the desired results.
