Something You Want to Know About AA and MP3

AA is a proprietary audio file format developed and supported by Audible, a leader in the US audio content supply industry. The AA format is a kind of audio file designed for storing spoken words. But unlike audio files such as MP3 or WAV, AA files can contain more information in addition to audio data, such as chapter markers, bookmarks, and more. Actually, the internal content of the AA file is stored in unprotected MP3 or ACELP format, but its encrypted Audible container applies certain DRM restrictions for copyright protection. Therefore, such DRM-protected AA files can only be played on certain devices. If the device you want to play with is not compatible with this format, then you have to convert AA format files to other common media formats.

Among all the audio formats, MP3 is the absolute mainstream. Foremost, MP3 format audio files have a small storage capacity compared to other audio formats. Secondly, MP3 format compressed music can be sampled at a variety of frequencies, from 64Kbps or less to save space, to 320Kbps to achieve the highest sound quality. Finally, most devices are currently compatible with MP3 audio files, which means that if you convert AA files into MP3 format, you can achieve cross-device playback on various devices.

What is a Filename Extension?

A file extension, also called a file suffix, is a mechanism used by the operating system to identify the type of file. It is a very important concept in the computer. Common file suffixes mainly include JPG image files, MP3 audio files, RMVB video files, etc., which are the suffixes of some specific files. The existence of the file suffix allows the computer to determine the file type, and then associate with the corresponding program to open it. Only in this way, the user can view the content of the file. Therefore, if a certain file loses its suffix name, then the computer cannot determine what type of file this file is, and we cannot access the content of the file.
