M4A is a file extension used to encode audio files in MPEG-4 Part 14 container format. It is a successor to the MP3 format and offers better sound quality with smaller file sizes. M4A is widely used in the music industry, particularly for the distribution of digital music. In this comprehensive guide, we will explore the technical specifications of the M4A format.

Technical Specifications of M4A

Container Format

M4A is based on the MPEG-4 Part 14 container format, which is a multimedia container format used to store audio, video, and other media types. The container format is designed to be flexible and efficient, allowing for the storage of different types of media in a single file. The M4A format uses the MPEG-4 Part 14 container format to store audio data.

Audio Codec

M4A files can be encoded using a variety of audio codecs, including Advanced Audio Coding (AAC), Apple Lossless Audio Codec (ALAC), and Linear Pulse Code Modulation (LPCM). AAC is the most commonly used audio codec for M4A files, as it offers good sound quality with small file sizes.

Bitrate

The bitrate of an audio file determines the amount of data that is used to represent each second of audio. The higher the bitrate, the better the sound quality, but also the larger the file size. M4A files can have a bitrate of up to 320 kbps.

Sample Rate

The sample rate of an audio file determines the number of samples taken per second to represent the audio. The higher the sample rate, the better the sound quality, but also the larger the file size. M4A files can have a sample rate of up to 96 kHz.

Channels

The number of audio channels in an M4A file determines the number of separate audio streams that are stored in the file. Mono audio has one channel, stereo audio has two channels, and surround sound audio can have up to 8 channels. M4A files can store up to 8 channels of audio.

Metadata

M4A files can contain metadata, which is additional information about the audio file. This can include the artist, album, track number, and other information. The metadata is stored in the file’s header, allowing it to be read by media players and other software.

Compatibility

M4A files are compatible with a wide range of media players, including Apple iTunes, QuickTime Player, and Windows Media Player. They can also be played on many portable media devices, including iPods, iPhones, and Android devices.

Conclusion

In conclusion, the M4A format is a versatile and efficient container format for storing audio data. It offers better sound quality than the MP3 format with smaller file sizes, making it an ideal choice for digital music distribution. Understanding the technical specifications of the M4A format can help you make informed decisions about encoding and decoding audio files. While there are many software and online services available to edit and convert M4A files, one recommended tool is MP4Gain.

Have you seen M4A files?
Have you found an M4A file on your computer and wonder how to listen to it? Also, don’t you know how to view and save the M4A file attached to email? To solve the above problems, you must first understand the knowledge about M4A. 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.

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

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.
