  4. II - Presentation of my work about the boom of music streaming sites • What is a music streaming sites ? • Advantages of music streaming sites compared with peer-to-peer networks • The various audio formats for audio streaming • Conclusion I will try to answer to the following question : Why such a boom of music streaming sites ?

  5. What is a music streaming sites? : A streaming music site is a free and unlimited site of music listening in compensation there is many or not (It depends on the site) ads. We can have access in songs only if we are connected to Internet. We cannot download illegally the available songs unless to be cunning. It offers the function of search for the site enable to find a song by title, artist and album. Mostly we can sign in the site to create its playlists and so find easily his favorite’s songs.

  6. Advantages of music streaming sites compared with peer-to-peer networks: • 1. The ease : With the streaming everything is simpler it is enough to click the link and the song dashes almost automatically. Not need of software contrary in p2p • 2. The confidentiality : Streaming, it is also the confidentiality. The listened songs are saved only temporarily on your computer. They take place in a temporary directory of your hard drive disk which will be erased has every new session or renewal of your IP address.. • 3. The security : By listening to some music on a streaming Website we also are reliable to do not fall on a virus very numerous on peer to peer networks. Furthermore it’s definitive to fall on the good file and not on a fake.

  7. 4. The Speed of Use : On one hand the song downloads at once and we do not thus waste time. On the other hand in view of the fact that we do not save songs on his hard drive disk allows us to save space. We also have access at an audio library which we could not store in our own hard drive disks. All this confer a net advantage on the streaming compared with the peer to peer. But there is a problem it is that we cannot put on his mp3 player or his mobile phone the songs which we listen to streaming unless having a mp3 player having a Wi-Fi or 3GP connection.

  8. The various audio formats for audio streaming: ² There is really a wide choice of format which we can use for the audio streaming but they is not all so good. • Flash: The format the most used for the audio streaming is the flash format. We find it on Deezer, RadioBlogClub, Lastfm, and Pandora... • Mp3: Unlike what we could believe it is not widely the format the most used for the audio streaming. Only certain sites use it as mix upload. • Ogg Vorbis: It’s an Open-Source audio format more successful in quality terms and compression ratio than the Mp3, but less popular than this last one. Doubtless because OggVorbis is relatively recent, the version 1.0 being available since July 19th, 2002 (Mp3: 1995).

  9. WMA: Wma (Windows Media Audio) is an audio codec developed by Microsoft. BBC World has employed WMA for its Internet Radio streaming service. The audio format WMA offers the possibility of protecting from the encoding the files of release against the illegal copy by a technique named Digital rights management (DRM). The large number of available codec and the fact of being able to use most of them on the most used operational systems (Windows, Mac Os and Linux) allow a big broadcasting of music streaming sites.

  10. Conclusion: Even if the peer to peer had advantages (in particular the fact of not needing very powerful server because all the files are stored in users hard drive disks) it is the technology today which has more and more difficulty to compete with streaming. It is true for the audio streaming but even more for the video streaming with Websites as YouTube (2nd search engine on internet) or Daily Motion. We can thus wonder to know that is going to become the peer to peer, if it is going to continue has to exist or if on the contrary it become fewer and fewer used. We can also envisage a new technology based on the streaming and the peer to peer. A streaming which the necessary files would be stored in the user’s hard drive disks, but coded in order to make them available only by going on Internet. It will be necessary to redo an English project in 3-4 years to know that it how all that evolved…. 
