Compare audio formats like M4A and MP3, AC3, WMA.

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.

M4A

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, characteristics of the m4a format

The M4A format is short for MPEG-4 part 14 and is a type of file created by Apple in 2004 from the QuickTime file format. It is a digital media container used to store audio components, but it can also contain other data (for example, images). The M4A is a file extension for an audio file encoded with Advanced Audio Encryption (AAC) which is lossy compression. M4A was generally intended as the successor to MP3, which was not originally designed for audio only, but was layer III in an MPEG 1 or 2 video file.

M4A Files Technical Details

M4A files are an improvement over MP3 files, basically due to their ability to offer lossless compression versus lossy compression from their competition. Files can be converted over and over from / to original audio and size. MP4 copying is restricted by DRM technology, but the M4A file type is easy to copy and distribute. For this reason, Apple uses M4A files for the sale of audio and the transfer of content to CDs and mobile music players. Being a strictly Apple product, it can be difficult to use these files in Windows, but iTunes for Windows makes it possible, as well as converting these files to Windows compatible audio formats (which involve lossy compression).

Developing

M4A files, are a type of audio files developed and popularized by Apple, since 2007 the songs purchased through the iTunes store have been in m4a format, therefore there are more than 15 billion files worldwide, MP4 and M4A files are usually confused and the two are quite similar, both are based on the MPEG-4 codec, however M4A is a file that only contains audio while the MP4 can also contain video.

What is the MP4 format?

Contrary to MP3 format, MP4 is not a video format as such, but it is a container that houses an audio track and a video track that can be encoded in different codecs.

MP4 is short for MPEG-4 Part 14, and is based on the specifications of the MOV video format, developed by Apple.

Because MP4 is a container format, its component parts, audio and video, can be encoded in different formats, which can be adapted to the implementation of the resulting file.

Generally these formats are, for AAC audio and H264 MPEG 4 video, both formats with an excellent compression / quality ratio, which allows MP4 files to be transmitted over the Internet without difficulties.

Due to the characteristics of the MP4, acronym of the English name Motion Picture Experts Group-4, in this type of container it is possible to include inside for example a complete film in high quality, which is also possible to do in a storage space really reduced.
