Convert 3GP to AMR

What is 3GP file?

3GPP Multimedia File (.3gp) is a file format developed by the Third Generation Partnership Program (3GPP) for multimedia content used with 3G mobile phones and other compatible devices. It is based on the MPEG-4 standard for audio and video, and is designed to store such types of audio, video, and other types of data, such as subtitles and images. It supports various audio channels, such as mono, stereo, 5.1channel, and so on. [ ⏩ ] 3GP file extension

What is AMR file?

The .AMR file extension is associated with the Adaptive Multi-Rate Codec (or AMR) audio file format. The format was developed by the mobile telecommunications industry and is now widely used in both cellular networks and Voice over IP (VoIP) applications. As its name implies, AMR is a multi-rate codec that utilizes a technique known as channel-dependent algorithmic switching to enable variable bit rates from 4.75 up to 12.2 kbps.

How to convert the file from 3GP to AMR?

To successfully convert the 3GP file to AMR, you should install one of the applications from the list. After installing the software, open the program and select the file you want to convert (file-name.3GP). The next step is to select the target format from the list, in this case AMR (usually converters allow you to convert to several different formats, so check out their features - maybe one of the available formats will suit you more than AMR).

What is a file conversion?

A data conversion is normally an automated process to some extent. The effect of the operation of one program is automatically the input product of another application. If that does not happen we need to help the process a little bit and convert the file on our own, e.g. 3GP to AMR. To obtain a matched structure of the data, it is necessary to use an appropriate converter.

Program for converting 3GP files to AMR files is a kind of a "binary code translator" compensating for the differences in the code or translating it in such a way so that another application could use it. For us, as users, the visible change will be only another file extension. (After converting the file, it will be the extension AMR, while before this step we had the 3GP file). For the programs, the difference is on a much higher level – either the application will be able to open a new AMR file, or not.
