And in java, from the downloaded mp3, select a discrete frequency map, write an array of sound amplitude values to a .txt file, for example, for every 3rd second. Save this .txt to the server, and ask the player along with the mp3’s and animate the picture fluctuations, focusing on the values of the array from the discrete card.
@Realetive: I didn’t say flash was unpopular. Written, if not in popular flash, then in java.

In HTML5, all audio and video tags are fully supported. Their support by your browser is a separate issue. Adiom had a question about creating an audio player, not a client-server-oriented application. I haven’t seen the Ipad work with Java… But with HTML5 it works quite well – I watch videos and videos without any problems. So the new standard, in my opinion, successfully fulfills its task – brevity of tags fights redundancy of solutions.
