Title: DIGITAL SIGNAL PROCESSING AUDIO (sound system)
The audio effects are artificially generated using various signal processing circuits and devices, and these sound effects are typically being performed using digital signal processing techniques. They can be done by Time-Domain Operations and Frequency-Domain Operations. Sound Processing is one of the many applications of DSP. Sound processing is vibration, as perceived by the sense of hearing. In more technical language, sound is an alternation in pressure, particle displacement, or particle velocity propagated in an elastic material or series of mechanical compressions and rarefactions or longitudinal waves that successively propagate through medium that are at least a little compressible (solid, liquid or gas but not vacuum)The effects of basic DSP operations are much noticeable in sound. Audio signal processing utilizes a wide variety DSP technique to produce different sound effects, which is the focus of this project. These sound effects are simulated in MATLAB or java. Audio Signal processing is one of the many applications of Digital Signal Processing. Different effects can be performed with various filters. Audio processing covers many diverse fields, all involved in presenting sound to human listeners. Three areas are prominent: (1) high fidelity music reproduction, such as in audio compact discs, (2) voice telecommunications, another name for telephone networks, and (3) synthetic speech, where computers generate and recognize human voice patterns. While these applications have different goals and problems, they are linked by a common umpire: the human ear. Digital Signal Processing has produced revolutionary changes in these and other areas of audio processing.
