Irrespective of the operating system your computer is using, one can be assured that the Mp3 files will work well in all the cases. The Mp3 format is the most robust and quality format to save audios and music.

The prime reason for the success of this format is that it utilizes the compression technique which makes it very effective. A specific compression technique is utilized by this format which reduces the size of the files substantially, without affecting the quality of the sound of audio. The process of compression involves the removal of all kinds of data, which cannot be heard by the human ears and then compressing the resultant file. This process makes it possible to compress the files as efficiently as possible.

The trade-off between the file size and audio quality can be balanced very well by the Mp3 formats. It is evident that if the file size of the music audio is large, the music is of high quality. On the other hand, if the file size is squeezed, the quality of the music sound deteriorates. The Mp3 file offers the solution to this problem as the format in which the file size is low as well as the quality of the music is high.

If you are falling short of memory on your smart-phone or your computer, you can convert the audio files in the Mp4 format to the Mp3 format. This will save the memory space as well as maintain the quality of the audio files.

Key Features of the MP4 Files

The Mp4 format is known for better utilization and better flexibility while usage. The Mp4 files are actually the containers and they are used to store the date. It should be emphasized here that they are used to store the data and not the code. The Mp4 files do not have a way to handle the coding associated with a file.

There are specific codecs, on which the Mp4 relies to handle the coding as well as the compression part. A large number of codecs are available but only a few specific ones work best with the Mp4 formats. For a player to play the Mp4 file, it must have a supported codec.

The Mp4 files can handle video, audio, texts as well as images. The key feature of the Mp4 files is the flexibility it offers during usage. Some of the common extensions related to the MP4 format are as follows:

  • MP4: Official extension
  • M4P: Audio Encrypted by Fair-Play
  • M4A: Non-Protected Audio
  • M4B: Podcasts and Audio-books
  • M4V: MPEG 4 Visual bit-streams

File Meta-Data

The Mp3 and Mp4 files, both support the metadata. These meta-data makes it possible to effectively use the home media servers as well as music player apps. The Metadata helps to store important details of the files like audio title, singer, etc. This Metadata helps to extract the information easily from the files, without scanning the complete files.

Conclusion

Thus, we have seen the key features of both the Mp3 and Mp4 files. While the Mp3 file supports only the audio format, the audio, as well as video formats, are supported by the Mp4 format. The Mp3 format is the best format for the audio files. For Videos, the Mp4 format is best and it is a very flexible format.
