Online Mastering vs a Mastering Engineer

When automated mastering wins

For demos, singles, beats, streaming releases, and anything on a budget or a deadline, automated mastering is hard to beat. It is instant, consistent, and free to try. AetherWave applies genre-tuned EQ, compression, and loudness and returns a 24-bit / 48 kHz WAV in seconds, so you can hear a finished result before you spend anything.

When a human engineer helps

A mastering engineer brings a trained ear, custom decisions, and revision passes that matter most on flagship releases, complex mixes, or full albums where cohesion across tracks is critical. Many artists use automated mastering for the bulk of their catalog and a human engineer for their biggest releases. Starting with a free automated master costs nothing and often gets you all the way there.
