Download Modelling digital musical effects for signal processors, based on real effect manifestation analysis For quite some time in the area of commercial utilization of digital audio effects, efforts have emerged to create simulate by software analog effects and effect processors This paper deals with the analysis of musical effects, the design of algorithms for simulating these effects, and their realization on both digital signal processors and the PC platform in the form of plug-in modules for the DirectX environment. It also deals with the problem of controlling the effect parameters and with subjective testing of algorithms, and it examines the fidelity of simulated effects as compared with the original.
Download Optimizing Digital Musical Effect Implementation For Harvard DSP Architecture In the area of digital musical effect implementation, attention has lately been focused on computer workstations designed for digital processing of sound (DAW – Digital Audio Workstation), which perform all operations with audio signals, such as routing, mixing, editing, effect processing, recording, coding, etc. They are in fact a combination of a powerful computer program and hardware cards with digital signal processors. Most of these operations, except editing, must be performed in real time. Until recently, all real-time operations were performed on digital signal processors. Thanks to the power enhancement of personal computer core, performing these operations in the CPU is currently possible. However, in most cases, digital signal processors are still used for these purposes because digital musical effect modelling is more effective and more precise with the digital signal processor. In addition to this, processing in digital signal processor saves the CPU computing power for other functions. This paper deals with optimizing algorithms of digital musical effects for DAW systems.
