RealMedia Variable Bitrate
| File extension | .rmvb |
| File category | video |
| Description | RMVB is a type of file that means the RealMedia Variable Bit Rate file and it’s made by Real Networks. The RMVB shares similar qualities with MPEG4 but its not the same from the RealMedia format that encodes at a constant value. Other variable bitrate files are DIVX and XVID. This file format is popular in Asia but less known in America and Europe. |
| Technical details | The compression of RMVB files is the same as the MPEG-4 part 10 encoders. The file type has remained unpopular because of its incompatibility with media players besides RealMedia. However, it is still very relevant in Asia. It is compatible with peer-to-peer sharing platforms and torrent programs. The amount of data in a set time frame can be altered by variable bit rate files. Therefore, there is less storage requirement with a decrease in quality but longer encoding process. |

MP3 Audio File
| File extension | .mp3 |
| File category | audio |
| Description | 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. |
| Technical details | 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. |
