  • Description
  • Files with .mp3 extension are digitally encoded file formats for audio files that are formally based on the MPEG-1 Audio Layer III or MPEG-2 Audio Layer III. It was developed by the Moving Picture Experts Group (MPEG) that uses Layer 3 audio compression. Compression achieved by MP3 file format is 1/10th the size of .WAV or .AIF files. The format gives advantages of streaming such audio files over the internet for listening online that was previously not possible due to the large file sizes of audio files. Sound quality of an MP3 audio file can be controlled by parameter settings such as bit rate, sample rate, joint or normal stereo.

  • Description
  • MP4(short for MPEG-4 Part 14) is a file format based on ISO/IEC 14496-12:2004 that is based on QuickTime File Format but formally specifies support for Initial Object Descriptors (IOD) and other MPEG features. It is mostly used to store video and audio but can also be used to store subtitles and still images. MP4 files are stored with the .mp4 extension. MP4 is an international audio-visual coding standard. Similar to most modern container formats, MP4 supports streaming over the internet. Due to the high compression used in MP4, the resultant files are smaller in size with almost all the original quality retained.
