When choosing free DAW (Digital Audio Workstation) software, consider the following key features: a user-friendly interface, support for VST/AU plugins, multi-track recording capabilities, basic editing tools (such as cut, copy, paste, and automation), and a variety of built-in virtual instruments and effects. It’s also important to check if the DAW allows for expansion through third-party plugins and if it has a supportive community or resources for learning. These features will ensure that the software meets your needs for creating and producing music effectively.
