Convert 3GP to MP3

Converting one file format to another may be necessary for various reasons. So, for example, you may want to convert 3GP to MP3 if your computer, phone or other device does not support 3GP 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.

The 3GP file contains multimedia data in an audio and video container format developed by the 3rd Generation Partnership Project (3GPP) consortium for mobile telephony. It is used to transfer audio and video over the Internet, as well as save videos captured on a mobile device. The finished video clips in 3GP have a small size compared to similar videos in other formats, however, this is justified by a rather low quality, for example, often many frames are presented in the form of colored squares. This format is used to play videos, most often on mobile phones. Its peculiarity lies in the size of the files being played - it is much smaller than, for example, avi. The disadvantage of 3GP is quality, but it is ideal for playing on mobile phones. A 3gp file is a small footage created for playback on portable devices (phones, smartphones, tablets, etc.).

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.
