Cassette Dubbing Optimizer

How it helps

Use it for a focused task

This page helps you plan a cassette dubbing session by calculating optimal recording levels and bias adjustments. You provide your source tape's peak level, the target tape type, and your deck's calibration quirks.

The calculator suggests settings that reduce distortion and preserve frequency response. Below the calculator, you'll find a plain-language walkthrough, tape type characteristics, common mistakes, and answers to frequent questions.

Start by selecting your source tape type from the presets or enter a custom peak level in dB. Choose the blank tape you'll record onto.
