What is test mastering?

Test mastering is a low-risk way to have your song mix processed by a professional mastering engineer before booking the final mastering. You send in your unfinished mix and receive a professionally mastered sample of your song back – this way you can hear the sonic difference and assess the final quality before making a decision. At Peak-Studios, test mastering is genuine studio mastering done by hand (no AI tools) and costs a one-time fee of €10 – with no obligation.
