M4A, which is short for MPEG-4
Developed by Apple in 2004, M4A is an audio file created in a multimedia format. It is used to store compressed video and audio files. Worth noting, M4A files can also store images. Using different codecs, you can compress the file with or without losses. M4A is an improved version of the mp3 format. You can convert it to other formats without any loss of quality and size. Playable on devices powered by any Apple platform.
Advanced Audio Coding (AAC)
This format stands for advanced audio encoding. Created as an alternative to mp3, it allows for compressing files at bitrates identical to mp3, obtaining high-quality sound. Files of the AAC format contain many sampling frequencies. Advanced Audio Coding includes 48 channels. This type of encoding is more efficient and includes a larger number of filters. Files of the Advanced Audio Coding format cut off the frequencies which the human hearing cannot perceive. This results in a reduction of the original file size.
