Convention Paper

Recording with Feedback Controlled Effective Bias

Authors: Jensen, Jørgen Selmer

AES Convention 70 · Paper 1852 · October 1981

Abstract

In magnetic recording, high frequencies present in the signal act as bias for lower frequencies. If supersonic bias is dynamically reduced by the same amount as the added effective bias of the audio signal, several advantages result. The theoretical aspects of constant effective bias, the implementation in a cassette recorder, and the resulting improvements in quality are described.
