MP3 and MP4 are just two phrases we frequently encounter in regards to networking files. We all know MP3 for audio files and MP4 for movie files. However, have you ever wondered about MP3 or MP4? Have you ever wondered what makes both similar-sounding formats so distinct from one another? In case you have, then this post will answer all of your questions.
Here, Colorfy will present to you the difference between MP3 vs MP4. This comprehensive comparison in the easiest word can help you understand them better. Thus, you will not be confused in deciding which to use.

What’s an MP3?
Before we can handle the gaps between MP3 vs MP4, let us do a fast recap on what an MP3 file is and its use. MP3 is a short-form to get MPEG-1 Audio Layer 3. It was created to provide us a method to store sound info in electronic form, but using a bigger file size than CDs’ structure.
MP3s do so with a mental trick: They begin by taking a first, uncompressed digital audio file (such as a monitor on a CD), and they then remove chunks of information in a manner in which the human ear is not likely to notice. It is a process called “lossy compression,” It is the same trick employed by JPEG documents to shrink the dimensions of photographs without affecting the crucial details, making it seem as great as the first. The same goes for MP3 files: Even though they take around a tenth of their storage size for a CD audio track, many people find them a decent listening experience.
What’s an MP4?
MP4 is a short form for MPEG-4 Component 14. Contrary to the MP3, which can be exclusively used for sound, an MP4 is a container that may be used to store music, audio, or other information like subtitles.
This makes it somewhat tricky to understand just what an MP4 is. Should you find one known as “Rocky.mp4,” can it be that the film Rocky, or can it be the film’s theme tune? Or can it be something else? To cut the confusion, Apple chose to begin using the .m4a file extension for MP4 files, which only contain sound, while .m4v is occasionally utilized to indicate a video. But because those are conventions, not rules, the only way to understand is to try opening the document with an MP4-compatible media player or analyzing this document’s contents.
However, what exactly does this have to do with MP3s you may be thinking about? An MP3 is both a file format and a codec – that means it can only manage sound using the lossy compression described previously. Since MP4 documents are containers, you may select many different audio codecs based upon what you need.
Typically, individuals will utilize the AAC (Advanced Audio Coding) codec. It is a lossy compression codec such as MP3, using the same bitrate choices for quality, but it’s a much better job of maintaining nuances and details in music in precisely the same file size as an MP3. But, Apple’s hi-res capable lossless audio codec, ALAC, is also an alternative for MP4 files that preserves all the detail of a CD or even a plastic record while keeping file sizes bigger than the first makes it a fantastic selection for archiving audio.
MP3 and MP4 – How They Operate?
MP3, having an audio-specific format, can’t compress movies. It typically eliminates sounds in the record outside the typical human hearing range with pulse code modulation, a less space-consuming and easy modulation, and a psychoacoustic model. In specific ways, what JPEG would be to pictures, MP3 would be to sound.
When there are no strict recommendations from MPEG-1 for MP3 encoders, you will find well-defined specifications for its decoder calculations file formats. This has caused flooding of MP3 encoders from the marketplace with hardly any decoders which are harmonious.
Nevertheless, the simple access to comprehensive information empowers users to pick the ideal encoder decoders. Simply speaking, MP3 is a trade-off between the quality of a solid and the total amount of space it occupies. To compress a sound document, it’s recorded using a lower bit rate resulting in the deletion of high-frequency noises from the document leading to a drop from the sound quality.
Additionally, there have several side effects of audio compression such as Split, compression artifacts (seems current, but not part of the original recording), ringing, etc.. Documents with arbitrary sounds and sharp strikes are also hard to compress. Its functioning is quite like that of the MP3, and it’s been created with mainly the mobile devices in your mind. But although the conventional prescribed document extension is.
Mp4, many businesses, in their quest to keep their identity, and come out with various extensions. A notable case in point is the .mp4a expansion from Apple Inc… Additionally, MP4’s skills to include audio, text, and video pictures make it even harder for your decoder to forecast the streaming of any specific MP4 file.
The difference between MP3 vs. MP4
MP3 is short for MPEG-1 Audio Layer 3. It’s a patented encoding format for digital audio. An MP3 file compresses this data using a 128 kbit/s setting, which contributes to a document that’s roughly 1/11 the magnitude of the initial data. The MP4 is a container structure. This usually means it may be used to save audio and/or video information. MP4 files may also be streamed on the net.
MP3 & MP4 are two distinct formats for files. They may appear related, and you may presume that MP4 is the newest creation of MP3; nevertheless, that’s not the situation. They’re two different technologies with various applications.
Uncompressed audio file is quite big and occupy a great deal of room. This is principal because of how audio is quite intricate, and also the translation of it into an electronic format may occupy a great deal of information. An MP3 file compresses this data using a 128 kbit/s setting, which contributes to a document that’s roughly 1/11 the magnitude of the initial data. The MP3 files can be made at lower or higher prices, with corresponding lower or higher resulting quality.
MP3 has become among the most frequently used audio formats and has become the standard for audio files for quite a while. Most digital music players utilize the MP3 design because of the default standard of digital audio compression for both transport and playback of audio.
MP4, on the other hand, relies on Apple’s MOV file sort. MPEG-4 Part 12 was developed in Apple’s MOV document and finally led to MPEG-4 Part 14, which is that the MP4 format. The MP4 is a container structure. This usually means it may be used to save audio and/or video information. MP4 audio and video may also be streamed on the net.
Since MP4 is a container format, it doesn’t have a typical way of programming the sound or video data. Instead, it utilizes codes that dictate the way the sound or video is going to be coded. Advanced Audio Coding (AAC) is the most popular codec for controlling sound in MP4 format.
MP3 is an audio compression format that’s used to compress and save audio on a pc. Comparatively, MP4 is a container structure used to save video and audio files. It may even save subtitles for a movie file. As a container, MP4 can store audio and movie files compressed in various styles, such as MP3.
But, because of this, MP3 players can’t typically play MP4 files and vice versa. Nonetheless, there are presently numerous mobile players and software alternatives available that may play both, by way of instance, VLC player, Winamp, etc.. This is principal because of how the MP4 format was steadily growing in popularity.

What One Should You Use?
If you presently have a huge selection of MP3 files, they have been created in 256kbps or higher. The odds are good you would not see much improvement in audio quality by re-encoding your own CD’s working with an MP4 file unless you are using some high-end audiophile equipment.
On the flip side, if you are considering ripping new CDs from scratch or switching analog sources to digital, an MP4 – particularly one which utilizes the lossless ALAC codec – would be the thing to do. You will have a practically flawless digital document, which could subsequently be converted into your selection of lossy formats afterward – such as MP3 if you are worried about backward compatibility with older devices. Lossless MP4 files occupy far more space, but if you’ve obtained the available hard disk space, they are worthwhile.
