M4a, what you should know about m4a
The M4a is, we could say, the audio part of what would generally be a Mp4. That is, a Mp4 that only contains audio information, it would be said that it is a m4a.
Since the Mp4 can contain, among other things, audio and video channels, but if it only contains audio, it was a m4a.
Initially the m4a as such did not become very well known. And it wasn’t until Itunes and the Ipod made it popular.
The M4a can also be used as a ringtone on iPhone phones.
Normally it is known that its decoding delivers a file with the same quality as the one that was originally encoded, that is, the M4a is of very high quality. Which is why it has gained a lot of popularity in recent times.
In addition to encoding without loss of quality, it encodes to save in very small spaces, which is another advantage that has brought them great popularity.
You can even compress or decompress at the same speed as mp3, and using the same bit rate as mp3 will take up less space than mp3.
One disadvantage, the most important, is that there are not so many devices capable of playing it compared to mp3, which is still the most widely used.
We could say that on a planet in which there are more devices than people, most of the users are not experts and then they will turn to the mp3, since it sounds good enough, it is the one that practically everyone can reproduce and even with easier to use. get, they are practically everywhere.
The M4a will then remain, at least until now, for the experts.
When using ALAC compression for the M4a, its highest quality is achieved, as there is really no loss of quality when compressing.
We have already mentioned in other articles that 95% of people cannot distinguish this difference.
However, the M4a has been gaining ground as people find out about its high quality. Not all software is capable of processing it. Luckily the Mp4Gain is able to normalize this format without any problem.
