wht is MP3? and wht is the differenct betwenn MP3 & MP4?

Answer 1

MP3 is an old audio-only format that was at the forefront of the current portable digital music player industry. It's currently the only truly universal audio format (hence the term MP3 players), but it sounds really bad (especially in the high range) compared to most newer audio formats like AAC (which is saved under the M4A extension) and WMA.

MP4 is a container format that can be used to collect multiple video, audio, photo, and/or text files into one single file. M4V is an alternate extension for MP4-compatible video, and M4A is the same thing for audio.

Answer 2

MPEG-1 Audio Layer 3, more commonly referred to as MP3, is a popular digital audio encoding and lossy compression format and algorithm, designed to greatly reduce the amount of data required to represent audio, yet still sound like a faithful reproduction of the original uncompressed audio to most listeners. It was invented by a team of German engineers who worked in the framework of the EUREKA 147 DAB digital radio research programme, and it became an ISO/IEC standard in 1991.


MPEG-4 Part 14, formally, ISO/IEC 14496-14:2003, is a multimedia container format standard specified as a part of MPEG-4. It is most commonly used to store digital audio and digital video streams, especially those defined by MPEG, but also can be used to store other data such as subtitles and still images. Like most modern container formats, MPEG-4 Part 14 allows streaming over the Internet. The official filename extension for MPEG-4 Part 14 files is .mp4, thus the container format is often referred to simply as MP4. Devices that play .mp4 files are referred to as MP4 players.

Now as u have understood MP3 & MP4 u can make out the difference.

Answer 5

mp3 has a number 3 on the mp
mp4 has a number 4 on the mp

just joking

mp3 is mpeg-1 layer 3
mp4 is mpeg-1 layer 4 but commonly called AAC (Advanced Audio Coding) for audio and other file extentions like .m4a, .mp4 it can be an audio or a video

did u like the joke part?

For those new to the digital music world, the MP3 and MP4 formats are compression technologies for converting standard analog audio tracks (like those on a commercial music CD) to smaller digital computer files.

The primary reason digital music formats have become so popular is that they deliver high quality sound at roughly one tenth the size of the uncompressed original. As a point of reference, a standard Audio CD can hold roughly 20 songs while a CD encoded with MP3 files can hold as many as 200 songs

Normally when sound is compressed, the quality is dramatically diminished but many empires were launched because of the MP3 format and its ability to deliver high compression rates with a minimum loss of sound quality.

The MP3 format became an official standard in 1992 and began the chain of events that eventually created many popular music encoding programs and playback devices.

Today, the sheer quantity of small handheld devices that can hold thousands of songs is mind-boggling, but the undisputed leader (by a wide margin) is Apple’s iPod, despite the fact it was a latecomer to the MP3 player party.

A big reason for the huge success of Apple’s music device was the launch of the iTunes online music store. It was the first commercially successful attempt at selling music at 99 cents per song but required an iPod if you wanted to take your purchased music mobile.

At the time, Apple was successful (when other weren’t) in convincing the music industry to allow them to sell copyrighted music in a digital format because of something known as FairPlay digital rights management (DRM). Remembering that this all came on the tails of the massive music piracy problem created by the original Napster file sharing system (Napster is now a legitimate online music company), Apple had to demonstrate that they could control how these digital files were used.

This is where the AAC format (Advanced Audio Coding, commonly referred to as MP4) came into the picture. Because Apple used a proprietary file format, they were able to limit how each file purchased on their system was used, which meant a single user could not purchase a song and share it with others .

Along with this digital rights management system, Apple also made claims that the sound compression technology was superior to the old MP3 format. While the technical data may support this claim, the reality is that most listeners don’t have the playback equipment (speakers) or the ears to tell any difference.

What is relevant about music purchased on the iTunes system in AAC or MP4 format is that it can only be played back in the iTunes software or on an iPod, while the MP3 format is supported by all music devices (including the iPod).

Your choice of playback systems will be the primary driver of which format is best for you so be sure you check your players supported formats before you begin buying or encoding your music.

Answer 7

MP3 is 3 layers of Mpeg type of music which is compressed under three layers

Answer 8

mp3 is short for media player generation 3 it plays your downloaded music . a mp4 can play your music and videos and is the 4th generation of media player.
