I'm trying to find a suitable language for developing an RIA to be able to tune an instrument via a website. I.E. what I need is:
1) Live input from a microphone
2) Get the volume level of different frequencies
3) Find the average or loudest frequency
4) Output the results

I know that the last 2 are possible but could I do the first two in Java via an applet online?
