Audio Compression

The project is about Converting different sound formats like :

CDA to WAVE
WAVE to MP3
3. CDA to MP3

CD Audio (.cda) : These tracks are audio files that can be stored on CD media.

MPEG Audio Compression :; This is one of many methods to compress audio in digital form trying to consume as little space as possible but keep audio quality as good as possible. MPEG compression showed up as one of the best achievements in this area.

Wave file format : It is a Windows' native file format for storing digit ....etc

Abstract—

Most psycho-acoustic models for coding applications
use a uniform (equal bandwidth) spectral decomposition
as a first step to approximate the frequency selectivity of the
human auditory system. However, the equal filter properties
of the uniform sub- b ....etc

Seminar Report on Audio Compression


INTRODUCTION

Large storage requirements limit the amount of audio data that can be stored on compact discs, flash memory, and other media. Large file sizes also give rise to long download times for retrieving songs from the internet. For these reasons (and others), there is considerable interest in shrinking the storage requirements of sampled sound.

Simple way of looking at audio compression

An audio signal can be compressed using digital filter. Digital fi ....etc

Abstract:

Digital audio broadcasting, DAB, is the most fundamental advancement in radio technology since that introduction of FM stereo radio. It gives listeners interference - free reception of CD quality sound, easy to use radios, and the potential for wider listening choice through many additional stations and services.

DAB is a reliable multi service digital broadcasting system for reception by mobile, portable and fixed receivers with a simple, non-directional antenna. It can be operated at any frequency from 30 MHz ....etc
