Convert AVI to MP3

Converting one file format to another may be necessary for various reasons. So, for example, you may want to convert AVI to MP3 if your computer, phone or other device does not support AVI 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.

AVI is a popular audio and video file format that was developed by Microsoft in 1992. It was the very first format for working with video-audio in the old version of Windows 3.1. Now the developers are updating it, they have improved the quality of compression and viewing of media files in this format. AVI is an abbreviation. Audio Video Interleave is fully written. Files with this extension can be played by various video players due to their simple architecture. AVI remains the most popular video format for viewing on a computer. It features high definition and retains the best quality when transcoding video files. In most cases, you do not need to install additional codecs to view clips in this format, since they are built into each player by default. This media container can contain multithreaded video and audio tracks and allow their synchronous playback. Videos with sound in this format are played by the standard built-in media player in all operating systems of the Windows family. Due to the sufficient popularity of the format, it can be opened not only in the Windows operating system, but also in Linux and Mac OS. In addition, files of this format can be opened in smartphones with Android OS and iPhones.

MP3 (formally MPEG-1 Audio Layer III or MPEG-2 Audio Layer III) is an encoding format for digital audio developed primarily by the Fraunhofer Society in Germany with support from other digital scientists in the United States and other countries. Today, most of the audio recordings that a person listens to almost every day are presented in the form of universal MP3 files, since they are the most common and demanded in terms of the format for storing audio information. MP3 format is a streaming format. This means that data transmission occurs as a stream of independent separate data blocks - frames. For this, the original signal during encoding is divided into sections of equal duration, called frames and encoded separately. When decoding, the signal is formed from a sequence of decoded frames. Unlike conventional archivers, which need to manage to compress information in such a way that not a single bit is changed in it after extraction from the archive, MP3 serves somewhat different purposes. In addition to mathematical compression algorithms, this format also contains the most complex algorithm for removing unnecessary audio information, based on the psychological and physiological characteristics of the human body.
