File extension.aiff Category Description Audio Interchange File Format (AIFF) was developed by Apple in 1988 and is most commonly used on Apple Macintosh computers. It is a leading audio format used by professional level audio and video applications as it is superior in quality to its more popular lossy MP3 format. AIFF is lossless and uncompressed meaning it takes up around 10mb for every minute of audio at 44.1kHz.
Actions Technical Details An AIFF file is divided into chunks made up of Common Chunks, Sound data chunk, Marker chunk, Instrument chunk, Comment chunk, Name chunk, Author chunk, Copyright chunk, Annotation chunk, Audio recording chunk, MIDI data chunk, Application chunk and an ID3 chunk - it is only the Common chunk and Sound data chunk that is required. It is an uncompressed format which assists rapid streaming of multiple audio files from disk to the application.
The file extension for the standard AIFF file is.aiff or.aif, however for compressed variants it should use.aifc. Associated programs Apple QuickTime VLC media Player Winamp Windows Media Player Developed by Apple Inc MIME type audio/aiff Useful links.
File extension.mp3 Category Description MP3 is a digital music format which allows CD tracks to be reduced to around a tenth of their normal size without a significant loss of quality. MP3 gets rid of a lot of the information recorded in a song that our ears are not able to hear and then uses complex algorithms to reduce the file size. This then enables you to get hundreds of songs on to a CD and it also has opened up a new market over the internet - the download market as download times have been significantly reduced. Actions Technical Details The MP3 format is a lossy format.
That means that an MP3 file does not contain 100% of the original audio information. Instead, MP3 files use perceptual coding. In other words, that means it removes the information that your ear doesn't notice thereby making the file smaller. The reason lossy formats are used over RAW is that RAW audio files are too large to travel over the internet at any great speed. By using lossy formats it enables even dial up users to download mp3 files at a reasonable speed. RAW file formats generally require 176,000 bytes per second compared to a lossy format which requires 17,600. The difference is massive and so are the download times.
