MP3 VS M4A: difference between MP3 format and M4A format

M4A vs MP3

MP3s are well known as a long-standing standard for digital music. But what is the M4A format of MP4 audio?

MP3 vs M4A

Is it the next generation MP3? Should I use the MP3 or M4A format to play and save my favorite music? In this article, we will explain in detail the difference between MP3 format and M4A format. We will also introduce TuneMobie Apple Music Converter, which makes it easy to convert M4A music and Apple Music songs purchased from iTunes store to MP3 format.

The term MP3 has become synonymous with digital music, just as Google has become synonymous with web searches. Not surprising, given that the MP3 file format is over 20 years old. However, MP3s have now been overtaken by other file formats. One of them is MP4. The name increase from 3 to 4 does not mean that MP4 is just the next generation of MP3.

Before addressing the differences between MP3 and MP4, let’s briefly explain what MP3 files are and how to use them. MP3 is an abbreviation for MPEG-1 Audio Layer 3. It was developed to provide a way to store audio information in digital format, but the file size is smaller than the format used on CDs at the time. The original uncompressed digital audio file (such as a CD track) is taken, then the data chunks are selectively removed in a way that goes unnoticed by the human ear, and then the saved file is MP3 audio. This is a process called “lossy compression”. It uses only one-tenth the storage size of a CD audio track, but most people find the listening experience to be good when listening to MP3s.

Difference between uncompressed audio and compressed audio

Do all MP3 files have the same sound quality? No, the difference can be seen. When creating an MP3 file from an audio CD or a vinyl record, you can select the bit rate and the sample rate. These two values determine the file size of your MP3 music, but more importantly, the quality of the sound.

Most MP3 files, especially when converted from a CD, are created at a sampling rate of 44.1 kHz. This is because it is the same as the sample rate used to create audio CDs. On the other hand, the bit rate of MP3 format can be set in the range of 8 kbps to 320 kbps. The difference between the two is huge: at 8 kbps, music sounds a bit better than poorly received AM radio. At 320 kbps, most people will find it impossible to distinguish between MP3 and CD. When MP3s go mainstream, file size is an important consideration, and if you reduce it to 128 kbps, the deterioration in sound quality will not be as noticeable. 128 kbps was preferred in the early days of the MP3 format because it is compatible with most MP3 playback devices, such as the iPod, but now all MP3 digital music players can process MP3 files from 8 kbps to 320 kbps. .

M4A format tips for MP4 audio
M4A format

MP4 is an abbreviation for MPEG-4 Part 14. Unlike MP3s, which are dedicated to audio, MP4s are container files that can be used to store other data such as audio, video, or subtitles. This makes it a bit more difficult to know exactly what MP4 is. If you find something called “Kids.mp4”, is it a movie, a movie theme, or something else? You can judge if you don’t play it with the media player software. To reduce the confusion, Apple has started using the .m4a file extension for MP4 files that only contain audio.

But what does this have to do with MP3s? MP3 is both a file format and a codec. In other words, MP3s can only process audio with the lossy compression mentioned above. However, since MP4 files are containers, you can choose from several different audio codecs to suit your needs. People often use the AAC (Advanced Audio Coding) codec. And MP4 audio M4A (* .m4a) files are also often called AAC files.

M4A

Apart from M4A, there are many other active audio formats.

m4a

For example, the popular MP3, AC3, WMA, OGG, etc. What is the difference between M4A and MP3, AC3, WMA? What’s better about M4A than MP3, AC3, WMA and OGG? Then read the next sentence to see the battle in audio compression format.

M4A and MP3: Both M4A (MPEG 4 audio) and MP3 (MPEG3 audio) are audio compression formats 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, aims to replace MP3 with a new standard for audio compression. However, when comparing M4A MP3 for sound quality, M4A is better. Generally speaking, it is recommended to store music with M4A audio at 192 kbps bit rate for good sound quality and small file size.

File size: In terms of file size, M4A is often believed to have superior sound quality than MP3 when encoded at the same bit rate. For example, with 128-bit AAC (M4A), a 4 minute song would be 3.8 MB. To maintain the same sound quality with MP3, it is necessary to encode at a rate of approximately 192 bits. Then the file size will exceed 3.8MB.

Compatibility: Currently, M4A is only used on PC, iPod and other Apple devices and is not as popular as MP3. In contrast, all computers, music players, and mobile phones can play MP3 files.

Tip: If sound quality is a priority, neither M4A nor MP4 is the best option. It is advisable to choose the uncompressed WAV format. However, the size of the WAV file is about 10 times that of M4A and MP3. Therefore, WAV, which takes up too much space when creating a music collection, is not the best format.

M4A, MP3 and WMA: WMA A lossy compression codec developed by Microsoft. Like other new formats, M4A and WMA have higher compression efficiency and better sound quality than MP3. Good sound quality, especially at low bit rates. As a result, WMA works well for low-bandwidth video streaming. Therefore, songs purchased from online music stores Napster, Musixmatch, and Wal-Mart must be stored in WMA. However, WMA cannot be played on Apple iPod, which is a shame.

Tips for other audio formats
In addition to the audio formats mentioned above, there are various music compression formats such as WAV, AAC, and ALAC. There is a difference in compression rate and sound quality.

1. 1. WAV
WAV is a standard Windows audio file format. Normally, it is treated as a format for uncompressed, linear PCM sampling data, but WAV is a so-called container format, and the data format is free, and it can also store compressed data such as ADPCM, MP3, and WMA. As it is uncompressed WAV, it has the same sound quality as the original CD, but the data is too large to use.

2. The differences between
M4A and AAC M4A and AAC are completely different. AAC is an audio compression format used in the “MPEG-2” and “MPEG-4” video compression standards. As a result of not being able to decode with MPEG, the compression rate is high and the sound quality is good. M4A is an extension attached to audio files compressed by the AAC (Advanced Audio Coding) standard.

3. 3. Differences between M4A and MP4 In
Simply put, M4A is just an extension that can store MPEG 4 audio and has an audio file. mp4 can store MPEG 4 video, various audio data, video data, image data, metadata, etc., including MPEG 4 audio.

Have you seen M4A files?
Wondering how to find M4A files on your computer and listen to them? Also, do you know how to view and save M4A file attached to email? To solve the problems above, you must first understand the knowledge about M4A. When I hastily searched the net for M4A related information, 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 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, and some tips on other audio formats like WAV, AAC, ALAC, etc. I will present one by one, so do not 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 video data in the MP4 file.

Compressed audio data is recorded in AAC or Apple Lossless (ALAC) format. Developed to become the new standard for compressing audio files, this new codec is the successor to MP3s, boasting better sound quality and smaller file sizes than MP3s.

M4A Compatible Devices and M4A Players
Seven years ago, Apple delivered iPads, iPods, and iPhones that swept through the Japanese mobile market like a tornado. Not only Apple products, but also iTunes and QuickTime media players support M4A, and it works well as M4A player.

Also, Windows Media Player can support M4A files. However, if you want a media player to read it, you can change it from M4A to MP4.

What is M4A?
Tip: It’s a lot of work for anyone who wants to play M4A on Xperia, Samsung, HTC, PSP, and other devices that don’t support M4A. It is a video / audio codec, so it is difficult to do. By the way, if you have a video converter with good quality, you can easily solve the above problems.

Reform H.264 video files like copy and paste with HEVC / H.265 encoding and HEVC MP4 format, 4K MP4 output, NVENC hardware encoding for H.265, maximum transcoding speed OR converting MKV, MTS, MP4, AVI, WMV to M4A encoded AAC, MP3, AC3 and other audio formats to show almost perfect performance for playback on Apple, Android.

What is the best way to use compressed sound sources like MP3, AAC and WMA correctly?

M4A

When listening to music on a smartphone or iPod, what you seem to know but not understand is digitally compressed sound sources like MP3, AAC, and WMA. Let’s think again about “in what format” and “how much bit rate” is good.

M4A

◆ World standard MP3, Apple standard AAC, Windows standard WMA
You all know that there are various formats of “digital sound sources”.

The best known is the WAV format, which is also used for CDs. Since it is an uncompressed format, there is no deterioration in sound quality and it is very versatile, but the capacity is not small, just over 50MB in 5 minutes.

Therefore, when used with a portable music player such as a smartphone, iPod, or Walkman, it is common to convert (= encode) from WAV to compressed sound sources such as MP3, AAC (M4A / M4P), and WMA.

By the way, compressed sound sources are used from the beginning for download distribution like iTunes. AAC for iTunes, MP3 for Amazon, and WMA for major national distribution sites are mainstream.

・ MP3 …… The oldest compression format established in 1995. There are many supported products, and it is the de facto standard that can be used in any case. “MP4” is a video standard, so don’t get it confused.

・ AAC (M4A / M4P) …… A standard established after MP3, which is a standard format for Apple products such as iPod and iPhone. M4P is a file protected by copyright. AAC is also used for audio on digital terrestrial broadcasts and digital BS on television.

・ WMA …… A format advocated by Microsoft. It has a strong affinity for Windows and many products are also used in voice recorders.

Based on these characteristics, let’s consider the compression format depending on the device used.

Let’s easily convert the sound source with a service that converts analog records into digital sound sources.

◆ User-friendly bit rate of sound quality and capacity is 128 kbps to 160 kbps
The problem is the compression rate (= bit rate) expressed in the unit of “kbps”. Difficult theory aside, it’s okay if you think the point is “bitrate = standard for numerically expressing sound quality”.

“Reduce the amount of data by reducing the sounds that are not harmful to the human ear” In a compressed sound source, the lower the bit rate, the lower the capacity, but the higher frequencies are cut off. So if you lower the bitrate too much during encoding, you will get some moody sound quality somehow.

・～ 96 kbps …… Since the sound does not lengthen, it is suitable for talk-centric radio programs, etc.
・ 128 kbps …… No matter who listens to it, there is not much discomfort. Suitable for pop and rock with PC speakers and car audio
・ 160 kbps …… Sound quality that can be satisfied even with general audio. Suitable for loud jazz
・ 192 kbps …… There are few glitches even when listening with headphones. Even classical music with a wide range is fine.
・ 256kbps / 320kbps …… High sound quality close to that of a CD (1411kbps equivalent)

What is the M4A format?

M4A

The M4A format is an extension attached to audio files, just like MP3. .m4a is compressed by the AAC (Advanced Audio Coding) standard, but AAC is based on the MPEG4 format. In the MPEG4 format that stores audio and video data, .m4a only records the audio data.

M4A

As part of the MPEG-4 standard, there are differences between MP4 and M4A. For convenience, iTunes separates M4A and MP4. M4A is a file format that stores audio only, and MP4 is a format that contains video and audio data.
So what are the advantages and disadvantages of files in M4A format?

merit:

Voice quality is lossless (lossless). The capacity is also small.
It is not protected by Digital Rights Management (DRM), so you have more freedom to edit and transfer.
If you rewrite the file extension from M4A to M4R in iTunes, you can set it as iPhone ringtone as is.
Demerit:

Other manufacturers can’t handle it
To play M4A files
You can play it on Apple devices like iPhone and iPod. It can also be played on iTunes, Quicktime, and Windows Media Player.
If you use professional conversion software to convert M4A format files into highly versatile MP3 format files, you can also play them on general players.

Difference between M4A and MP3
MP3s are more versatile. In terms of sound quality, the later m4a is said to be technically superior, but there won’t be much of a difference at 128kbps or higher, which is used for musical purposes. Also, mp3 is not good at low bit rates of 100 kbps or less and the sound quality deteriorates a lot, so m4a is better when using such low bit rates. For users of Apple and iTunes products, generally speaking, the color coding of “mp3 that emphasizes versatility and m4a that emphasizes sound quality” is common.
M4A files have a higher compression ratio than MP3 files and sound better than MP3 files when encoded at the same bit rate. In terms of file size, M4A is often believed to have superior sound quality than MP3 when encoded at the same bit rate.
For example, for equivalent sound quality, M4A has a 192-bit rate and MP3 has a 256-bit rate.

M4a, what you should know about m4a

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.

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.
