Abstract
A digital audio signal processing system is disclosed that enable flexible coexistence of signals having different formats in the same hardware architecture. The system comprises at least one input, at least one first format transformer, and at least one digital audio signal processor. The at least one input is arranged to receive at least a first digital audio signal having a first format comprising a first symbol resolution and a first symbol distribution. The at least one first format transformer is arranged to transform the first digital audio signal to a second digital audio signal having a second format comprising a second symbol resolution which is different from the first symbol resolution and a second symbol distribution which is different from the first symbol distribution based on at least a first parameter and a second parameter, wherein the first parameter is associated with a number of integer symbols of the second format and the second parameter is associated with a number of fractional symbols of the second format. The at least one digital audio signal processor is arranged to process the second digital audio signal to produce a third digital audio signal. Corresponding computer program product is also disclosed.
