![]() The Moving Pictures Experts Group (MPEG) officially announced it as a global standard in 1997. AAC is touted as being able to maintain better audio quality at the same bit rate when compared to MP3.ĪAC was developed with the cooperation of companies including AT&T-Bell Laboratories, Fraunhofer IIS, Dolby Laboratories, Sony Corporation, and Nokia. It is a lossy compression standard, which was designed to be the successor of the MP3 format. mp3 extension.ĪAC is the acronym for advanced audio coding. The files compressed using the MP3 compression technology bear the. It is widely used for streaming and storage, and is also the default standard of storage and playback in most audio players. Today, MP3 is the most popular audio format in the world. it has been adopted by the Moving Pictures Experts Group (MPEG) as part of their MPEG-1 standard, and was later extended to the MPEG-2 standard. MP3 was designed and developed by a team of engineers from Fraunhofer IIS, University of Hannover, AT&T-Bell Labs, Thomson-Brandt, and CCETT. ![]() ![]() Typically, using the setting of 128 Kbps, an MP3 compression will result in a size reduction of 1/11 of its original uncompressed CD version. The main aim here is to reduce the required bandwidth, by significantly reducing the size of the audio file via data compression, while still allowing it to sound like a faithful reproduction of the original to a majority of the listeners. It basically works by compressing the audio data file on the basis of certain predefined rules of encoding. The MPEG-1/ MPEG-2 Audio Layer III, popularly known as MP3, is a digital audio encoding format, especially designed for the transfer and playback of music. In the following lines, we shall examine both these compression techniques, and run an AAC vs. AAC and MP3 are two such audio compression formats, though being lossy, have over the years gained a lot of popularity. There are many good compression techniques out there, that are able to sufficiently reduce the size of an audio file, while at the same time maintain optimum levels of audio quality. So while we have managed to obtain the ability of packaging thousands and thousands of songs into our miniature music players, we have had to sacrifice at least some amount of audio quality, owing to the compression methods that are used to achieve the size reduction of these audio files. In order to obtain a thing, something of equal value must be lost. However, at high enough bit-rates, they are both nearly indistinguishable from the original source and compared to the loss-less formats, and take up only a tiny amount of space on music players. AAC and MP3 fall under the category of ‘lossy’ audio formats, as in both of them, certain amount of original audio data is lost during compression. ![]()
