Introduction

Recording Zoom meetings has become a common practice for professionals and educators alike. However, the raw audio from these recordings often contains background noise, uneven volume levels, or other imperfections that can detract from the listening experience. Fortunately, Audacity, a free and open-source audio editing software, offers a robust solution for enhancing Zoom recordings on Windows 11.

Understanding Zoom Recording Formats

Zoom typically saves recordings in two formats:

  • MP4: A video file that includes both audio and video streams.
  • M4A: An audio-only file.

For audio editing purposes, the M4A format is preferable as it simplifies the process by focusing solely on the audio component.

Locating Your Zoom Recordings

By default, Zoom saves recordings in the following directory on Windows systems:

CODEBLOCK0

Each meeting's recordings are stored in a subfolder named with the meeting's date and title. Within these folders, you'll find the M4A audio files ready for editing.
