Audacity

Audacity is a free and open-source digital audio editor and recording application that has been a staple in the audio editing world for many years. While Audacity itself does not inherently feature AI-powered stem separation or advanced noise reduction in its core functionalities, it supports a wide range of plugins, some of which may incorporate AI-based audio processing techniques developed by third parties.

Audacity offers a comprehensive set of tools for basic to advanced audio editing tasks that are highly relevant to video creators. These include trimming and arranging audio clips, mixing multiple audio tracks, applying various audio effects, adjusting levels, and performing noise reduction using traditional methods or supported plugins.

Its open-source nature and extensive community support mean that it is a constantly evolving tool with a wealth of online resources and tutorials available. For video editors who need a powerful yet free audio editing solution, Audacity provides a versatile platform that can be extended with plugins to potentially incorporate AI-driven audio processing capabilities as they become available.
