Equalizer source code

Hi All

I have build an equalizer for my own application. It works more or less but there are some problems. It is not working as well as the winamp it does. Is there a source code of Winamps included visiual equalizer? Or can someone of the developers guide me, to solve the small failures in my code. I can post what I have done up to now:

1: DMC data array, 44100 samplerate 2Byte stereo.
2: FFT n=2048 scaled by x[i] /=n/2; y[i] /=n/2;
3: db = 20*log10(x[i]*x[i]+y[i]*y[i])
4: visual the calculated frequences and DB freq range: samplrate/n
5: update the process during sound play all 1/10sec

result is a visualisation of y=DB / x=frequences but it is not so nice like the small equalizer in the left to corner of winamp, why? Is there someone what i forgot?

Many thanks
to the developer or someone they can support me to solve my errors.
