Already explained in the previous article, read here.
.MP4 versus .M4A
M4A stands for MPEG 4 Audio and is a filename extension used to represent audio files. Both .MP4 & .M4A are absolutely same container format, the reason for the existence of two different filename extensions is that the .M4A files are used to represent audio only MP4 files.
Which is the best M4A media player?
No doubt VLC media player can play it very well, that's the only media player that a user need these days.
.M4A versus .MP3
M4A is similar to MP3 but it's a bit more efficient, three simple comparisons can be made based on:
Quality: M4A files has better quality than MP3 files for same size. iTunes uses 256 Kbps VBR M4A normally.
Size: M4A files have smaller size for same quality.
Compatibility: MP3 files are compatible with almost every device & media player, however M4A files are also very popular these day due to Apple iTunes & now almost all players that supports MP3 supports M4A too.
In which format you should store/download music?
If you want better quality for same size, go for M4A. Download iTunes M4A instead of 320Kbps MP3 as mostly website provides MP3 converted from iTunes M4A, so no logic in downloading converted MP3 file when you can download original iTunes M4A having same size.
If your device suppoers M4A & you're still listening to MP3, it's time for you to move on. Any queries? You can ask in comments below.
