    Hello i've modified Visualizer-WavForm example named VizWav.

    I want to :

    a) Record Load and save a mp3 file but i am new and i don't understand the data stream from examples in the forum.
    What code shall i put in 116 , 125 and , 131 lines ?

    b) The in_db function ( line 139 ) converts a samle of sound in db ( decibels ).

    If i put it in btnStartWav_Click ( line 111 ) so to be synchronized with the spectrum , what shall i write there ?

    Many thanks Enthousiastic !!!!!!!!!!!!!
