Authors: Stephani, Otfried

AES Convention 68 · Paper 1735 · March 1981

Abstract

Pre- and post-echoes may disturb considerably listener's artistic sensations, especially in exciting or dramatic program titles; therefore, anti-echo measures should be a must for quality disc record manufacturers, at least regarding the classical repertoire. During the three disc manufacturing steps - transcription, electroforming, and pressing - numerous parameters exercise an influence on the echo formation. Within the scope of this report, only a few items of all facts checked within the echo field may be discussed. The article will present outward forms of pre- and post-echo which are characteristic for the .AM. three stages and it will yield the attempt to explain the mode of echo origin. A few indications on how to minimize the echo formation as much as possible will be given.
