What Is Audio Mastering? The Final Step Before Release

What is audio mastering? The final polish that adds loudness, clarity, and consistency before Spotify, Apple Music, or CD release.

Audio mastering is the last production stage before distribution. It optimizes a finished stereo mix for loudness, tonal balance, stereo image, and true peak safety so the song translates on phones, cars, clubs, and streaming platforms.

Key takeaways
