Information about ASF and MP3 file formats

🔸 File format ASF MP3
🔸 Full name ASF - Advanced Systems Format MP3 - MPEG-1 or MPEG-2 Audio Layer III
🔸 File extension .asf .mp3
🔸 MIME type video/x-ms-asf, application/ audio/mpeg, audio/MPA, audio/mpa-robust
🔸 Developed by Microsoft Fraunhofer Institute
🔸 Type of format Digital container format Digital audio
🔸 Description Advanced Systems Format (formerly Advanced Streaming Format, Active Streaming Format) is Microsoft's proprietary digital audio/digital video container format, especially for streaming media. ASF is part of the Media Foundation framework. MPEG-1 or MPEG-2 Audio Layer III, more commonly referred to as MP3, is an audio coding format for digital audio that uses lossy data compression. It is a common audio format for consumer audio streaming or storage and a de facto standard of digital audio compression for the transfer and playback of music on most digital audio players.
🔸 Technical details The format does not specify how the video or audio should be encoded; it just specifies the video/audio stream structure. This is similar to the function performed by the QuickTime, AVI, or Ogg container formats. One of the objectives of ASF was to support playback from digital media servers, HTTP servers, and local storage devices such as hard disk drives. Lossy compression is designed to reduce significantly the amount of data required to represent the audio recording and still sound like a faithful reproduction of the original uncompressed audio. For example, an MP3 file created using the setting of 128 kbit/s will result in a file about 1/11 the size of the CD file created from the original audio source.
