Pro Tip
AI mastering has evolved immensely — it’s now good enough for Spotify, Apple Music, SoundCloud, and playlist placement. But for major releases, consider sending your tracks to a seasoned mastering engineer after AI runs. A human ear can balance emotion, nuance, and musical intention in ways algorithms still can’t.
