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.

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.

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
