Often audio files are saved with .AMR extension. It signifies compromised audio to reduce bandwidth usage. While most devices come with an in-built player to run the AMR files, only a handful of tools can play the audio files. As a result, the options are restricted. Many devices cannot play the files, and you need to convert the same into another format.
MP3 is the common file format into which you can convert the AMR file. However, it is not easy to convert AMR to MP3, especially when you don't have the right set of tools or guidance. Similarly, when you try to convert MP3 to AMR, you may encounter different problems.
So, to ease the conversion process for you, we have shed light on the best solutions to interchange the two most popular audio file formats used in most applications.
In this article
What is AMR and why does it matter?
AMR is an audio file format, also going by the name of Adaptive Multi-Rate ACELP CODEC. It is a compressed file whose frequency range reduces bandwidth consumption during transmission. Any audio file based on speech format is usually transmitted through the AMR technology. The files are more efficient and can be scanned easily for malfunctioning or tampering with the main audio content. One of the main applications of the AMR file is in cellular data recording and transfer from one device to another.
The difference between AMR and MP3
When audio is recorded, the original file is so huge that transmission is impossible. Even if the bandwidth is more, transferring such a file slows the network and even introduces corruption and interference. That's why the files are compressed in the form of AMR or MP3 file formats. Both follow a compression technology, but they have subtle differences.
MP3 compression reduces the file size to the minimum and allows digital transmission. It is also widely supported by most devices. On the other hand, AMR files have a slightly larger size and are more efficient in encoding speech. However, people need to convert AMR to MP3 due to device incompatibility, lower sound quality, and poor performance.
