Sophisticated recording studio tasks are now achievable at home, thanks to readily available tools and software.

Audacity: A Free Yet Professional Audio Editor
While recording is simplified, audio editing remains crucial for polishing recordings. Audacity, a free and open-source software, stands out as a powerful tool used by both amateurs and professionals. It offers a comprehensive suite of features in a user-friendly interface. Audacity’s editing process resembles word processing, allowing you to visualize audio as waveforms and manipulate them through cutting, pasting, and deleting sections.
You can rearrange audio segments, incorporate multiple tracks for mixing background music and sound effects, adjust fade-in and fade-out effects, manipulate playback speed, and apply various filters. While mastering all its features takes time, the latest version boasts improved usability and installation. A comprehensive English manual is available at manual.audacityteam.org for guidance.
