Popular compression and lossy format with small file size and far from the highest sound quality. The emergence of the MP3 format was made possible by the joint efforts of a development team of almost 40 people who have been working on the project for several years. Compared to lossy files, MP3 songs take up much less disk space thanks to a special algorithm. Other advantages of MP3 include excellent compatibility with various programs and audio devices. Despite the fact that, due to the age of MP3, today it does not shine with compression efficiency, its popularity remains very high due to its versatility - the extension is supported on any operating system, a lot of both standard and specialized multimedia software plays this file format. MP3 files can be created with high or low bit rate, which affects the quality of the resulting file. The principle of compression is to reduce the accuracy of some parts of the sound stream, which is almost indistinguishable to most people's ears.
The AIFF extension is an audio format file developed by Apple Computer in 1988 based on Electronic Arts' IFF format, and is most commonly used in Apple Macintosh computers. Contains CD-quality audio that is stored in an uncompressed lossless format. The content of the file is uncompressed PCM data, a digitized analog audio signal. Like any uncompressed file, AIFF files take up much more disk space than their compressed counterparts: one minute of stereo audio at 44.1 kHz sampling rate and 16 bits takes about 10 MB. The standard file extension is .AIFF or .AIF, for the compressed version the .AIFC extension must be used. AIFFs are widely supported and can store LPCM, they are suitable file formats for storing and archiving the original recording.
