“I wanna use a program on an .m4a file, but the program can’t handle .m4a. It can handle .aac, however, and the codec of the file is MPEG-4 AAC. Is there a way to convert to .aac (and preferably converting back) without re-encoding?”A question from superuser.com.
This kind of questions are actually not rare online. So many people are searching for solutions on how to convert M4A to AAC free. Here in this guide, you would be listed with the best M4A to AAC converter tool and detailed steps on how to convert M4A to AAC format.
Part 1: Brief introduction to M4A and AAC format
A file with the M4A file extension is an MPEG-4 Audio file. They’re most often found in Apple’s iTunes Store as the format of song downloads. Many M4A files are encoded with the Advanced Audio Coding (AAC) codec in order to reduce the size of the file. Some M4A files may instead use the Apple Lossless Audio Codec (ALAC). However, there are still many M4A files that come with no AAC codec. That’s why we may need to convert M4A to AAC.
AAC, which stands for Advanced Audio Coding, is a digital audio file type that has been promoted as the successor to the MP3. AAC generally offers higher-quality sound than an MP3 while using the same amount of disk space or less.
Many people think AAC is a proprietary Apple format, but this is not correct. AAC was developed by a group of companies including AT&T Bell Labs, Dolby, Nokia, and Sony. While Apple has adopted AAC for its music, AAC files can actually be played on a range of non-Apple devices, including the game consoles and mobile phones running Google’s Android OS, among others.
