Download Digital Signal Processors for Real-Time Audio Processing We analyze the requirements for digital signal processors used in audio applications. Methods for assessing the real computing power expected from them are presented. Proper requirements for a real-time development platform are also described. Code development tools are also included. Finally a review of common processors is done according to those criteria.
Download Enhanced quality and variety for chorus/flange units Chorus and flanger are two classical effects that can be found in any current digital audio FX unit. Available chorus/flanger just translate into digital implementations the behaviour and parameters typical of cost-sensitive analogue realizations. But they can be greatly improved on a digital implementation with simple additions to the software. After an introduction to chorus/flange and their digital realizations, we address two such additions (randomized modulation law, and application of energy envelope for noise control), and then discuss further improvements easily achiveable by digital means (multiscale implementations).
