What is M4A?

m4a

M4A is the file extension for audio files encoded with Advanced Audio Coding (AAC), which is a lossy compression. M4A is often considered the successor to MP3, which was not originally designed for audio, but rather for layer III in MPEG 1 or 2 video files. M4A stands for MPEG 4 audio.

M4A file format

The M4A and MP3 file extensions are used for audio-only files. Audio-only MPEG 4 container files typically have the M4A file extension. M4A files are not protected. Protected files usually have the M4P file extension.

AAC or M4A files have better quality and smaller file size than MP3 files. Due to some improvements to the format, M4A files sound better than MP3 files when encoded at the same bitrate, such as:

Perceptual-based compression: If not within the range of human perception, sound data can be lost without significant impact on quality.
A smaller sample block size of 120 or 128 samples is used instead of 192 for changing (or transient) signals, allowing for finer detail when needed.
The block size in still images, 1024 or 960, allows less data to represent parts of the music that do not have the same complexity compared to MP3’s 576-sample block.
