The M4A Format Part 3

How to convert audio to M4A format?

Mp4Gain can do all these conversions

iMP3 to M4A – Although M4A is not as compatible as MP3, the audio quality of M4A format is much better than MP3 for the same size. So for Apple users, it is really a good way to convert MP3 to M4A format if you want to import more songs to the device. FLAC to M4A : FLAC is also a lossless audio compression format, which can reduce the size of the original file to half the size of the original file under the premise of lossless sound quality. For users who want to listen to music, FLAC offers an unprecedented musical feast. However, if you are using an iPhone or other Apple device, you must convert FLAC to a format that Apple can read, such as M4A, before you can play it.iiiWAV to M4A : WAV is a format commonly used by Microsoft and IBM. Compared with M4A format files, apart from the reason why Apple series products do not support playing WAV files, WAV format files will also take up more disk space.
How to convert video to M4A format?
iMP4 to M4A – MP4 is a most common format for storing video and audio data. If you want to extract audio files from MP4 video with lossless sound quality, the preferred method is to remove the video data and keep only the audio.

The M4A Format Part 2

M4A vs. MP3

Some people say that M4A, as a format for storing audio, can be considered the successor to MP3 format. However, compared to MP3, the advantage of M4A format is that it can compress the smaller file while keeping the same bit rate. The main stereo bitrate parameters of M4A files are 128 Kbps, 192 Kbps, and 256 Kbps (Note: Bitrate refers to the amount of data that can be transmitted in a specific time. Usually, your drive is Kbit/s or Mbps, i.e. the amount of data that can be transmitted per second kilobits and how many megabytes of files can be transferred per second (regardless of the unit used, the higher the number, the higher the speed and quality If you know more about encoding music, you should know that M4A audio files in 192Kbps parameters can get the highest quality music with the least memory consumption, for more details please read below .

Quality – The audio quality of ALAC compressed M4A files is very high as both original sound waves are lossless. AAC compressed M4A files have lossy compression. By comparison, M4A performs better than MP3 at the same bitrate, especially below 128Kbps.

File Size – File size and quality are directly related to bitrate. As bit rates increase, so do audio quality and file sizes. For example, to get the same quality audio file, MP3 needs to be encoded at 192 Kbps, while M4A only needs 128 Kbps. From this point of view, M4A files take up less space.

Compatibility: The MP3 format certainly ranks first in the audio market for compatibility, almost all software and hardware can play MP3 files. However, M4A is relatively limited and can only be used on Apple brand computers, iPods, iTunes and other software/hardware.

The M4A format

M4A is an extension used to compress MPEG-4 encoded files.

The official extension of MPEG-4 is the MP4 format, which contains audio and video files. The standard audio format in MP4 files is undoubtedly M4A. In fact, the M4A format was not very well known before, it was not until 2007 that Apple first used M4A, AAC, ALAC, etc. such as iTunes and iPod song recording formats, and slowly became more widespread.

Bottom – M4A format can be perfectly read on iTunes, iPod and other Apple devices. But compared to MP3 format, it is much less compatible with other brands of products.

What is M4A?

m4a

M4A is the file extension for audio files encoded with Advanced Audio Coding (AAC), which is a lossy compression. M4A is often considered the successor to MP3, which was not originally designed for audio, but rather for layer III in MPEG 1 or 2 video files. M4A stands for MPEG 4 audio.

M4A file format

The M4A and MP3 file extensions are used for audio-only files. Audio-only MPEG 4 container files typically have the M4A file extension. M4A files are not protected. Protected files usually have the M4P file extension.

AAC or M4A files have better quality and smaller file size than MP3 files. Due to some improvements to the format, M4A files sound better than MP3 files when encoded at the same bitrate, such as:

Perceptual-based compression: If not within the range of human perception, sound data can be lost without significant impact on quality.
A smaller sample block size of 120 or 128 samples is used instead of 192 for changing (or transient) signals, allowing for finer detail when needed.
The block size in still images, 1024 or 960, allows less data to represent parts of the music that do not have the same complexity compared to MP3’s 576-sample block.
