Difference between MP3 and MP4

By Jaxson

Main Difference

The MP3 and MP4 are the different types of audio formats by nature and from both of them, it is the MP4 that has the ability to play the video as well. These two organizations of sound pressure depend on psychoacoustic pressure strategies. Mp3 has picked up ubiquity in view of their progressive pressure limit. Clients could pack sound to sizes that were sensible for web exchange. There are a few constraints to MP3 that are outlandish some have been tended to in later pressure designs. These incorporate events specific to echoes and different examples that include unpredictable sound. Mp3 depends on a pressure method that expels sound information of sound that is not regularly capable of being heard by the human ear. The outcome is a little record size and sound that appears to be equivalent in quality to numerous. Mp4, on the other hand, was initially focused on low-speed web media. It appears to be appropriate in view of its ability for quality media rather little documents. In spite of its unassuming introductory objective mpeg-4 position has continued and keeps on coordinating a portion of the most unmistakable brands of media codecs in the business sector. Mp4 offers pressure for numerous Media, including sound, video and new backing for blended Media. It has gained the enhanced productivity and adequacy in its pressure. Mpeg-4 pressure has fit numerous record augmentations which have been displayed as one clarification of why it hasn’t accomplished the reputation of MP3. At the point when managing psychoacoustic pressure, you instantly need to consider the way that sound information is being expelled. For some, however, mp3 and mp4 pressure have supplied a quality that is calculable with a size that makes for accommodation. The future media looks universal than any time in recent memory and mp4 has connected its history of information and experience to giving more sound, video and blended media than MPEG ever have before at a superior quality and in smaller sizes.


The term of MP3 is used for showing the expression of the MPEG – 1 Audio Layer 3. It is a sound encoding arrange that uses a calculation called “lossy” pressure that massively lessens the information required for the sound recording without irritating its quality. On the seventh of July, 1994 the format of MP3 was released for the first time by the Fraunhofer Society with an encoder called 13enc. The record expansion name of .mp3 was presented just on the fourteenth of July, 1995 until which MP3 documents had the augmentation .bit. This format is known as the lossy compression that implies every time something is compacted with it, some data is lost. This data cannot be recouped. At the point when encoding to MP3 (changing over some sound information to it), the encoder is shrewd. The human ear cannot hear certain sounds which are covered by different sounds. This implies when encoding certain sound examples, some sounds can be forgotten (as they won’t listen). This makes it conceivable to pack sound by an element of around 5, without a recognizable change in the sound of the music. Numerous individuals like to utilize MP3 documents to duplicate music so they can hear it out on their PC. Record organizations don’t care for it when individuals utilize the Internet to impart these MP3 documents to each other. They think it is an infringement of their copyright. The record commercial ventures have an exchange bunch called the RIAA that has taken individuals to court for sharing music. An Internet site called Napster was closed down in view of this. Napster has since re-opened, yet does not give individuals a chance to share MP3 documents any longer.


MP4 stands for MPEG-4 Part 14 that a sight and sound compartment design standard determined as a piece of MPEG-4. MP4’s preference over different arrangements because of its capacity to handle advanced recordings, content, pictures separated from computerized sound documents and the ability to stream documents over the Internet. The format of MP4 was released for the first time in the year of 2002. It is a computerized mixed media holder organize in such an exclusive way that it can be used to store video and sound, however, can likewise be utilized to store other information, for example, subtitles and still images. Like most cutting edge compartment designs, it permits spilling over the Internet. The main authority filename augmentation for MPEG-4 Part 14 records is .mp4, but other kinds of formats are also functional for the same purpose.

Key Differences

  • The MP3 format can provide your audio services only, but the MP4 is able to offer you Video, Text and image services along the audio.
  • MIME Types of MP3 are audio and MPEG. In contrast, the MIME types of MP4 are video/mp4, audio/mp4, and application/mp4.
  • MP3 was announced earlier for the general public.
