MP4 is a container format that can store both audio and video compressed in different formats, along with subtitles. It allows streaming over the internet and supports high quality audio and video playback. MP3 is an audio-only compression format that reduces file sizes while maintaining good sound quality.

Because MP4 is a container format, it does not have a standard method of coding the audio or video information. Instead, codes dictate how the audio or video will be coded and possibly compressed. For audio, Advanced Audio Coding, or AAC, is the most popular codec for compressing audio for transfer on the internet.

If an mp3 file is recorded and compressed properly the quality can rival that of an actual CD. New technology is emerging that will allow you to “stream” the file so that the audience doesn’t have to wait for the entire file to download before they can hear it.
- 9. Disadvantages of mp3 The file size is still larger than a Real Audio file and a whole song would still take quite awhile to download over a normal phone line connection. Your audience must download and install a helper application or plug in to hear the sounds. Its small size lends to easy copying and distribution over the Internet.
