When I hurriedly searched for M4A-related information on the net, there were many technical terms that were difficult for beginners to understand, and some of the information was scattered and not very useful. What exactly is M4A? How is it different from the popular MP3 and AC3 audio formats?

Don’t worry, the text includes what is M4A in easy to understand words, how to play M4A, the difference between M4A and MP3, AC3, WMA, WAV, AAC, ALAC and other audio formats. , I will introduce it one by one, so please don’t miss it.

What is M4A?
M4A is one of the audio file recording formats, which is an extension of the MP4 file format defined by the MPEG-4 standard for audio. In other words, M4A is a file created without any video data in the MP4 file.

Audio data compressed in AAC or Apple Lossless (ALAC) format is recorded. Developed to become the new standard for audio file compression, this new codec is the successor to MP3 and boasts better sound quality and smaller file sizes than MP3.

M4a gain – with Mp4Gain

To achieve the effect that mp3gain did on mp3s, Mp4Gain can do it on most audio and video formats. M4a Gain is something that Mp4Gain performs as one of its most important functions. It ensures that all m4a have the same loudness, all with the same volume level, optimized to sound better and at the right level. It’s as simple as loading the m4a (or m4a) and clicking a button.

What is M4A?
Tip: It is very difficult for anyone who wants to play M4A on Xperia, Samsung, HTC, PSP and other M4A incompatible devices. It’s a video/audio codec, so it’s hard to do. By the way, if you have a video converter with good quality, you can easily solve the above problems.

Compare audio formats like M4A and MP3, AC3, WMA!
Apart from M4A, many other audio formats are active. For example, the popular MP3, AC3, WMA, OGG, etc. What is the difference between M4A and MP3, AC3, WMA? Where is M4A superior to MP3, AC3, WMA and OGG? Then read the next sentence to see the battle of the audio compression formats.

M4A and MP3: Both M4A (MPEG 4 audio) and MP3 (MPEG3 audio) are audio compression formats and were developed by the Motion Picture Experts Group (MPEG). Next, I will introduce the differences between M4A MP3 in terms of file size, sound quality, and compatibility.

Sound quality: The M4A format, known as Apple Lossless Encoder, points to a new audio compression standard instead of MP3. However, when comparing M4A MP3 for sound quality, M4A is better. Generally speaking, it is recommended to store music with M4A audio at 192kbps bitrate for good sound quality and small file size.

File Size – In terms of file size, M4A is often believed to offer superior sound quality to MP3 when encoded at the same bit rate. For example, at 128-bit AAC (M4A) speed, a 4-minute song would take up 3.8 MB. To maintain the same sound quality with MP3, it is necessary to encode at a rate of approximately 192 bits. So the size of the

Description M4A files are a type of audio file developed and advanced by Apple. Since 2007, music purchased through the iTunes store has been in the m4a format, so there is great confusion of more than 15 billion files worldwide. MP4 and M4A are two very similar formats, based on the MPEG-4 codec. However, M4A is a file that only contains audio, while MP4 can also contain video.

Technical details M4A files outperform MP3 in terms of compression scale and sound quality. The M4A file uses the Apple codec and is the home of MPEG-4. The main advantage of M4A is that the files are compressed but lossless. This means that they can be decoded to their original quality. Another advantage of M4A files is the lack of digital rights management (DRM), which means they are less restrictive.

Description MP4 files (MPEG-4 Part 14) are multimedia files. MP4 is a format that can store video, audio, and subtitle data (depending on content). Since stores like iTunes have been using this format, and it is used with iPod and PlayStation Portable (PSP) files, MP4 files have become more common.

Technical details MPEG-4 Part 14 or MP4, formally ISO / IEC 14496-14: 2003, is a multimedia file format called Part MPEG-4. It is most commonly used to store digital video and digital audio streams, especially those defined by MPEG, but it can also be used to store other data such as subtitles and still images. Like most modern container formats, MPEG-4 Part 14 allows streaming over the Internet. A separate track is used to include sequence information. The only official file extension for MPEG-4 Part 14 is .mp4.

M4a, what you should know about m4a

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.

M4A format information

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.
