Audacity is an open-source desktop software that provides multi-track audio editing and recording. It operates as a cross-platform desktop application available for Windows, macOS, and GNU/Linux, allowing users to manage audio projects locally on their hardware.

The software serves as a comprehensive tool for recording live audio and editing existing sound files. It is used for a variety of use cases including podcast production, music mixing, and general audio enhancement.

This architectural shift aims to modernize the software while maintaining the core functionality that allows users to record and mix audio without a subscription model. The software is designed for individuals and creators who require a dedicated audio workstation for tasks ranging from simple voiceover recording to complex multi-track arrangements.

Audacity is licensed under GPLv3 and serves as a widely used free tool for basic to intermediate audio engineering. It is a versatile, no-cost option for those who need a reliable audio editor across different computing environments.
