Convert MPEG to AAC

Converting one file format to another may be necessary for various reasons. So, for example, you may want to convert MPEG to AAC if your computer, phone or other device does not support MPEG format. Also, conversion is often required to reduce the file size, since the original format takes up too much space in the device's memory. Perhaps you just need to extract the audio track from the video file, in which case converting the video to audio format is a good option. In any case, with the help of our converter, you can easily complete the required task. Below you can find out some details about the original and new file formats.

In January 1988, an expert working group on coding of moving images was formed within the framework of the joint information technology technical committee JTC1 of the International Organization for Standardization ISO and the International Electrotechnical Commission IEC, which was tasked with developing standards for image and sound coding with the aim of eliminating redundancy. MPEG compression standards were developed by Moving Picture Experts Group. This technology defines the compression standards for both audio and video information and makes it convenient for transmission in broadcast. There are many versions of the format - MPEG-1, MPEG-2, MPEG-3, MPEG-4, etc. MPEG-1 is a lossy compression standard for video and audio. It is designed to compress VHS. Perhaps everyone is familiar with the MPEG-2 format. It is this format that underlies DVD-Video discs. The MPEG-2 format is also the basis for digital television standards. The MPEG3 standard was originally developed for use in High Definition Television (HDTV) systems with a data rate of 20-40 Mbps. The new MPEG4 standard, which appeared at the very end of 1999, offers a broader view of media reality. The standard defines the principles for working with content (digital representation of media data) for three areas: interactive multimedia itself (including products distributed on optical discs and over the Internet), graphics applications (synthetic content) and digital television (DTV).

Advanced Audio Coding, also known as AAC, is similar to MP3, although slightly more efficient. This means you can have files that take up less space but still have the same audio quality as MP3s. The best evangelist of this format today is Apple's iTunes, which made AAC so popular that it became almost as widely known as MP3. AAC is capable of achieving more flexible and efficient, and therefore better quality audio coding. As a result of the widespread use of the MP3 format, the AAC standard has not yet acquired the popularity comparable to that of MP3. Nevertheless, AAC is the main format in the popular iTunes Store, iPods, iTunes, iPhone, PlayStation 3, Nintendo Wii and DAB + / DRM digital radio. Most audiophiles who value the best possible sound quality tend to avoid MP3, AAC, and other digital audio formats because these formats use compression to create smaller files. The trade-off is that the upper and lower limits of the audio range are lost. Most average listeners don't notice loss, but for sound aficionados it can be a barrier.
