Part 2. What is the difference between AMR and AAC format

AMR stands for Adaptive Multi-Rate, and it is a compressed audio file that is used for speech coding and audio recordings on mobile phones and VoIP apps.

AAC, on the other hand, is a widely used audio format. Standing for Advanced Audio Coding, AAC uses lossy digital compression that reduces the file size while maintaining decent file quality. Additionally, the AAC is used by Apple iTunes and iTunes store as their default encoding method. It is used as a standard format for a large number of players, devices, and platforms.

If you are looking to record voice, the choice between the AAC and AMR would depend on the device. If voice or audio has to be recorded on a mobile phone, AMR is a good format to consider as it is designed for the purpose and can be easily stored on your phone.

On the other hand, if the voice is to be recorded using your computer or any other device, AAC is the preferred format owing to its wide use, quality, and compatibility.
