Android Question Vizartest

Hello .
Vizartest is a program that borrows routines from artest and Visualizer-WavForm.

As you see the audio files are saved , in created VizWav folder ( line 115,116) and the file will have the name VizWav0.wav , VizWav1.wav , VizWav2.wav etc

The problem is that i cannot record a second file pressing the button btn_Rec and making the opposite of Recording sub , that i called Playing i can't see the sum displaying in DbLbl.Text.
( i want to see the db not only during recording but during playing also )

Can you send me the correct code please ?

Many thanks Enthousiastic
