Advanced Systems Format File

File extension .asf
File category video
Description The Advanced System file is a media file used by Microsoft Window Media Player for streaming online audio and video files. The media container determines the data stream structure but not data encoding. So, the files encoded by Microsoft developers contain the .wmv or .wma extensions while other files have .asf extension. The ASF has a MIME type that allows files to be sent via the internet. Therefore, it can play audio and video directly while downloading data online.
Technical details The .asf file comes with audio, video, and metadata just the same as the MP3. It defines the album, artists, and so on. Using this file, streaming can be done in a similar way to other formats. This makes user access to the file once some bytes have been downloaded while the downloading continues and the user watches. However, it has a maximum resolution of 352×288, which is adjudged small because it is designed for streaming.

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 storing audio files and audio streaming. MPEG programmers designed the format. 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 a smaller size of tracks. As a result, one compact disk can contain several hundred songs. MP3 is compatible with all the most popular operating systems and is supported by most modern DVD-players and music systems.

Technical details

Before 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 frame. It involves the spectral limit technology that requires a continuous input signal to provide the use of two adjacent structures.

When spectral deleting is over, the file is to be compressed with mathematic methods. If necessary, the 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 a significant deterioration in sound quality.
