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.

What is OPUS file?
The OPUS .OPUS file extension is a lossy-compression audio file format used primarily for voice or audio transmission over the internet. It was developed by the Xiph.org Foundation and is an open-source compression technology. The audio files can be streamable and have low latency, meaning they can be played instantly without lags. OPUS audio files have a wide range of supported audio codecs, allowing users to play or convert the file with any compatible media software. [ ⏩ ] OPUS file extension
Software, that you can use to convert
How to convert the file from AMR to OPUS?
To successfully convert the AMR file to OPUS, 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.AMR). The next step is to select the target format from the list, in this case OPUS (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 OPUS).
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. AMR to OPUS. To obtain a matched structure of the data, it is necessary to use an appropriate converter.
Program for converting AMR files to OPUS 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 OPUS, while before this step we had the AMR file). For the programs, the difference is on a much higher level – either the application will be able to open a new OPUS file, or not.
