Microsoft Audio/Visual Interleaved
|Description||AVI basically stands for Audio and Video Interleave, it has an extension written as .avi and users use this very format to store audio and video on their PC which was developed by Microsoft in 1992 for its Video for Windows project. It allows the simultaneous playback by storing video and audio into a single file, the simple architecture of .avi format allows it to run on various operating systems such as Windows, Mac, Linux, Unix and it is also supported by various web players as well.|
|Technical details||AVI format uses the support of Resource Interchange File Format (RIFF) where the whole data is stored into chunks and each chunk gets recognized by a FourCC tag. Out of these individual chunks, the first one can be recognized by the hdrl tag and it can decode the chunk containing metadata for the video and the second chunk gets recognized by the movi tag and it contains the actual audio and visual data which makes up the AVI movie. It uses less compression rather than the MOV and MPEG file formats.|

MP3 Audio File
MP3 (formally MPEG-1 Audio Layer-3 or MPEG-2 Audio Layer-3) is a digital format for storage of audio files as well as for audio streaming. The format was designed by MPEG programmers. It is one of the most required codecs for digital coding. The format is widely used in various file-sharing sites for evaluation downloading.
Due to lossy compression in this audio format, it is possible to compress CD tracks up to 1/10 of their original size while maintaining high playback quality. Moreover, it can be encoded at higher or lower bit rates to adjust the resulting quality. Overtones, which cannot be perceived by a human ear, are removed. Complex algorithms allow for smaller size of tracks. As a result, one compact disk can contain several hundred songs. MP3 is compatible with all most popular operating systems and supported by the most of modern DVD-players and music systems.
Prior to MP3 introduction, MPEG-1 had been widely used. That format contained not only audio data, but images as well. MP3 breaks an audio file into parts of the same length. When the processing is over, each part is packed into its own frame. It involves the technology of spectral limit that requires a continuous input signal to provide the use of two adjacent frames.
When spectral deleting is over, the file is to be compressed with mathematic methods. If necessary, compression rate can be changed, even inside the same frame. Files of 128 kbit/s have 11-fold compression. Further reduction of the file size will lead to significant deterioration in sound quality.
