Abstract

1. Device for generating reverberation for analog audio signals, comprising an A/D converter for converting the analog audio signals into digital audio signals, a processing unit for processing the digital audio data, a D/A converter for reconverting the processed digital audio data and a microprocessor controlling the device, the processing unit exhibiting an audio data store and a 16-bit computer for additions and multiplications, which are connected to lines for the digital audio data, characterized in that the converters (AD, DA) are designed for processing 12- or 14-bit audio data and in that the controlling microprocessor (MP) is connected to the lines (4) for the digital audio data, designed for internal 16-bit processing and used as computer for all-pass calculations, which executes multiplications which are limited to particular values which result from very few steps such as 0.5, 0.625, 0.75, 0,875 by shifting and, if necessary, adding digital values.
