ok. How to destroy it. Just to see, I moved the "Viz.DrawWaveFormStart" into the Wave_Capture sub. No go! The wave does not scroll and the mp3 breaks apart!

No, because the when thread that the wav draw routine runs it will be continually initialized.

The two need to run totally separately.

Where can I put the Viz.DrawWaveFormStart so that the wave starts without a button or is that not possible?

You can put it straight after the MP.Play call in Activity_Create

I have to go out shortly, if you get any problems, post a message and I'll look at it when I get back, or in the morning.

Great, this is going to take some time to digest. Great work! I will try to include the WaveDraw class into my app AND get the gradient to work. If I get it to work, I will post it here to finish this thread.

Cheers.

Steve, its working! (Jumping for joy). The touch to end the app gives an error but the gradient works thanks to you. Now I just need a few more panels with different displays, FFT etc.

Yes, Fft I've not looked at that. Hopefully someone will give us some direction there. Otherwise it's back to school I think.
