AIFF Technical Specifications

File extension.aiff
File categoryAudio
Stands forAudio Interchange File Format
DeveloperApple Inc.
OverviewAIFF is an uncompressed audio file format. It keeps the original file without losing any data. This is the main reason why these files require more storage space. One minute-long audio requires nearly 10MB space. It is widely used by Apple Macintosh/Apple Mac and also musicians use this format for their recordings. Exact copies of music can be formed using this format with the added benefit of sound quality, which is well maintained in these files. Though it follows lossless format(not compressed), yet, there is another variant of it named AIFF-C developed by Apple afterwards and it is the compressed version. The only disadvantage of these files is a large size.
Technical descriptionMostly AIFF files have uncompressed Pulse Code Modulation(PCM) data which means at regular intervals the amplitude of the analog signal is reduced from continuous-time signal to a discrete-time signal and every sample is quantized to the closest value. An AFF file has various parts which are known as chunks and each chunk has its own ID which is mostly termed as FourCC. This ID is a sequel of four bytes which distinctly identify data formats. The several chunks found in this format are Common, Sound data, Marker, Instrument, Comment, Name, Author, Copyright, Annotation, Audio recording, MIDI data, Application, and ID3. The first two chunks are essential every time(Common chunk and Sound data Chunk). Lastly, these files have the capability of storing Metadata in five chunks-Name, author, comment, annotation and copyright. Metadata delivers information about the data that is data about data.

Any Movie, video or Audio file can be easily downloaded or streamed online with this extension which can be free or chargeable as well, such as downloading from iTunes. The payment can be made using credit or debit cards. These files may also include audio books, photos, podcasts, songs, movies, not making them limited to just audios and videos. This format has become more common as they are being used in iPod and PlayStation Portable(PSP). Commonly portable media players are advertised as “MP4 players” although they are capable of playing other media format as well like ‘AMV format'.
Technical descriptionMPEG-4 files are officially named under extension .mp4 and this is the only official extension for MPEG-4 PART-14 formats. These files were introduced in 2001 under the standards of ISO/IEX 14496-1:2001. It runs on AAC encoding which restricts the users from copying the data of the files. The data embedding can be done on these files using any private stream. For instance, hint tracks to add the streaming information into the file. These files are similar to most of the modern containers containing data information which allows internet streaming.
