what is mp4 player?

Answer 1

A portable/non-portable device which can play music files(songs!) encoded (writen) in the .mp4 format. Most players can play mp3 songs which are music files written in the .mp3 format, I am hoping you know what an mp3 player is.
MP4 (also known as AAC-advanced audio encoding)files are more cmpressed than MP3, usually the size of an MP4 file is half that of the corresponding MP3, for the same song duration.
But the quality is the same. A 64kbps mp4 song will sound same as a 128kbps mp3 song, which means an mp4 file will require half the space. So if you can fit 60 mp3 songs on a disk or cd etc, you can fit 120 of the same songs if they are written as mp4.

Answer 3

MPEG-4 Structured Audio (MP4) is a standard that specifies sound not as audio data, but as a computer program that generates audio when run.

When we hear a sound, we are sensing fluctuations of air pressure with time. The temporal structure of the pressure waveform has a significant effect on whether or not we find a sound pleasing or interesting.

This structure happens on several different time scales. Notes in a musical composition change on a time scale of hundreds of milliseconds. The timbre of sounds changes on a time scale of tens of milliseconds. The actual sound waveform changes on a time scale of tens of microseconds.

When programmers write software to create audio content in a conventional language like C or Java, much of the effort focuses on managing these three time scales of sound. Since the code is structured around timing issues, it is difficult to group all the code for modeling a specific musical instrument in one place. Instead, the code becomes separated into different sections for different time scales, and the methods of communicating between the time scales become hard to track and modify. In MP4-SA (programming language), time management is a part of the language itself.

so MP4 Player is a flash based Digital audio player capable of viewing images, videos, and text files.

Although commonly called MP4 players, many of them are unable to play MP4 format videos and are limited to proprietary file formats such as MTV, DMV, MPV and AMV. They are a kind of the S1 MP3 Player.

Maybe the players are now coming that play the MP4 Format....
