What Is Audio Compression?
Audio compression is the process of reducing the file size of an audio file while keeping the sound quality as close to the original as possible. It works by removing unnecessary or less audible data from the audio stream.
Compressed audio files are easier to store, faster to upload, and ideal for sharing on messaging apps, email, websites, and social platforms. Popular compressed audio formats include MP3, M4A, and OGG.
