Simulation and Analysis of Audio Signal Processor
An Audio Signal Processor analyze sound signals, process them and explore the signal properties. This paper is a part of the work carried out by the authors for designing the Audio Processor in MATLAB software providing basic functions to read, play and write the sound signal along with signal processing toolbox, which includes numerous functions that work on signals. A unique feature of the pa...
متن کاملAudio Noise Masking Countermeasures and Voice Spectrum Analysis
Using audio noise to mask confidential conversation and to provide a countermeasure to eavesdropping is a useful technique that has been utilized for many years; however, it is a basic technology that is often misunderstood and improperly implemented. This article is intended to provide a good understanding of the effects of voice band noise masking, and some guidance about proper implementation.
متن کاملSpeech Coding Development for Audio fixing Using Spectrum Analysis
A new method for the enhancement of speech signals contaminated by speech-correlated noise, such as that in the output of a speech coder, is presented. This module is based on numerical speech processing algorithms which modelise the infected ear and generates the stimulus signals for the cilia cells (brain). The method is also based on constrained optimization of a criterion. This interface us...
متن کاملRobust spread-spectrum audio watermarking
We present several mechanisms that enable effective spreadspectrum audio watermarking systems: prevention against detection desynchronization, cepstrum filtering, and chess watermarks. We have incorporated those techniques them into a system capable of reliably detecting a watermark in an audio clip that has been modified using a composition of attacks that degrade the original audio characteri...
متن کاملSimulation of Digital Audio Compression
This paper presents the digital data compression of multimedia transmission system. Digital audio compression is a scheme, which allows efficient storage and transmission of audio data. The main objective of this research is to show the program in MATLAB for Moving Pictures Expert Group (MPEG-1) audio encoder and decoder for layer-1, which will be analyzed in future on Digital Signal Processing...
