3GPP2 (3G2) is a multimedia container format designed for third generation (3G) code division multiple access (CDMA2000) networks. Since CDMA is a technology for mobile, the 3G2 format allows mobile phones on CDMA networks to capture, save, deliver, and play media over high-speed wireless connections.

MPEG 4 Audio (M4A) compresses and encodes audio files by using one of two coder-decoder algorithms: Advanced Audio Coding (AAC) or Apple Lossless Audio Codec (ALAC). M4A files are smaller in size while simultaneously better in quality than MP3 files, with which it shares the most similarities, in comparison to all other audio file formats.

 

How to open an M4A file?

M4A files open in most well-known, audio-playback programs, including iTunes, QuickTime, and Windows Media Player. For Apple users, iTunes is the default program to open M4A files. For Windows users, the default program is Windows Media Player. Users can also preview M4A files by highlighting the file and pressing the spacebar.
