problem with msgeq7 audio analyser chip

hello,

i using msgeq7 chip project, , seems of bands intertwined how.

if example run sound test goes 20 20000hz (for example this: https://www.youtube.com/watch?v=y_nplcdydwo) @ first band slow rise in values, slow descent, the second band values start rising, @ points, example while third band starts going down, , fourth starts rising, third bands values jump somewhere near maximal values, , after few moments jump down near zero. same kind of thing happens in of higher frequency bands well.

my code reading chip seems fine:

code: [select]


void eqread(void){
digitalwrite(msg7reset, high);
    delaymicroseconds(1); //not necessary
    digitalwrite(msg7reset, low);

    (int x = 0; x < 7; x++){
        digitalwrite(msg7strobe, low);     
        delaymicroseconds(36);
        int spectrumread = newvalues[x] = analogread(msg7dcout);
        digitalwrite(msg7strobe, high);

    }
}


i calculating average of last 20 values each band, add smoothing values.


has ever had similar experience?

thank you.
