Audio signal processing is a subfield of signal processing that is concerned with the electronic manipulation of audio signals. Audio signals are electronic representations of sound waves — longitudinal waves which travel through air, consisting of compressions and rarefactions.

We focus on the spectral processing techniques of relevance for the description and transformation of sounds, developing the basic theoretical and practical knowledge with which to analyze, synthesize, transform and describe audio signals in the context of music applications.

We propose a psychoacoustically motivated method to analyze the quality of reverberation and other audio signals. A time-varying loudness model is used as a front end to produce a visual display of a signal which emphasizes its perceptual features.

Oct 7, 2016 · Audio processing accounts for differences in sound and adds a variety of effects and modifications to ensure optimal sound quality. Video processing, on the other hand, modifies the video signal to ensure video is as close to the source signal as …

Digital Signal Processing generally approaches the problem of voice recognition in two steps: feature extraction followed by feature matching. Each word in the incoming audio signal is isolated and then analyzed to identify the type of excitation and resonate frequencies.

Lecture 2: Audio Signal Processing Fundamentals. The goal of this lecture is to provide an overview of the basics of digital audio. Analog Audio Signals. Before the advent of digital audio, most audio systems/technologies were analog.

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.

Presents a comprehensive introduction to audio processing for students in media technology and signal processing; Builds a foundation for audio applications based on mathematical equations, presented in a way understandable to students without a math background
