Here comes the package.

first, install the PureCOLOR-500-Installer.exe, is needed to customize the EQ Bars.
For more options then, press F1 and check the external Lib Helpfile

If you need more transparency for the EQ i can add a Alpha Layer.

here is a pretty good exemple from Dobro to  make a good spectrum with Fmodex Dll.
i use it to make my (pretty good) webradio player.

hi ars , thanks and hello (jmg49 on french pb board)

i used either fmodex and mp3d lib from inc. example , i will stay on mp3d with v2m support and EQ visualization

fmod doesn't play .v2m file format .... so .exe size is bigger 

it does the work,

thanks to all,

[~Ar-S~]

Please Add d3dx9_43.dll to your zip

[inc.]

Just simple install directx9c. This Demos require DX9.

[waste]

done !

[inc.]

Just a quick Reply.

i found a sourcecode and some nice effects you may be interest for a VU Meter:
see attachment

[waste]

line effect with reflection is great !

thanks

bass lib is used in this case, good for learning
