What is AC3 file?
The AC3 (.AC3) file extension is an audio file format created by Dolby Labs for Dolby Digital audio. The AC3 file format is also known as Audio Coding 3. The AC3 format was designed for digital video and eMedia applications. The AC3 file specification defines a data structure containing sub-streams of sound including up to 6 mono or 5.1 channel surround sound. [ ⏩ ] AC3 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.

Software, that you can use to convert
How to convert the file from AC3 to AMR?
To successfully convert the AC3 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.AC3). 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. AC3 to AMR. To obtain a matched structure of the data, it is necessary to use an appropriate converter.
Program for converting AC3 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 AC3 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.
