Convert MPEG to M4A

Converting one file format to another may be necessary for various reasons. So, for example, you may want to convert MPEG to M4A 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).

M4A is a file extension encoded with the AAC codec. An audio-only MPEG 4 container typically uses the M4A file extension. Compared to MP3, M4A has better sound quality and smaller file size. Contains audio encoded using the Advanced Audio Coding (AAC) or Apple Lossless Audio Codec (ALAC) codec. M4A files are close to .MP4 video files because both file types use the MPEG-4 container format. But M4A files only contain audio data. It aims to surpass MP3 and become the new standard for audio compression. M4A is pretty much very similar to MP3, but is designed to have better quality at the same or even smaller file size. The M4A format was first introduced by Apple. The format type is also known as Apple Lossless Encoder (ALE). The M4A format provides good compression with high sound quality and is widely used by Apple to distribute music through the iTunes Store. Songs that include copyright protection have the .M4P extension. Many programs support playing M4A files, including VLC, iTunes, QuickTime, Windows Media Player (v11 requires K-Lite codec pack), Media Player Classic.
