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 digital ....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 fil ....etc

Abstract:

A digital audio broadcasting system that is capable of providing a large number of high quality stereophonic channels to mobile receivers in an environment with severe multipath delay and fading. Optimum combination of frequency and time diversity to guarantee robust performance in the mobile channel, with its multipath delay and frequency-selective fading effects. The system is based upon a dynamic single channel per carrier assignment of each stereo channel to many carriers. Inter symbol interference degradations caused by multipat ....etc

An image defined in the real world is considered to be a function of two real variables say x,y.

Before going to processing an image, it is converted into a digital form. Digitization includes sampling of image and quantization of sampled values.

After converting the image into bit information, processing is performed.

This processing technique may be,
Image enhancement
Image reconstruction
Image compression

Image enhancement refers to accentuation, or sharpening, of image features such as boundaries.

Image restoration is con ....etc

Data Compression

Abstract :

It is very interesting that data can be compressed because it insinuates that information that we generally pass on to each other can be said in shorter information units (infos). Instead of saying yes a simple nod can do the same work, but by transmitting lesser data. In his 1948 paper, A Mathematical Theory of Communication, Shannon established that there is a fundamental limit to lossless data compression. This limit, called the entropy rate, is denoted by H. The exact value of H depends on the informatio ....etc
