When you're ready to play the mp3 files, enable the AVS window back so you can see the visualization. Sounds noob, but that's the only way, don't you get it? ;)

i am not realy into programming but there is a way to make a visualization that detects the file extension???
like:
if *.mp3 then run oscilloscope
if not run warever...
in visual basic
sorry to be souch a pain but if you give me a north

no, not really. If your programming knowledge is too poor to identify the type of a file then tackling a problem like writing an entire music visualisation application will be well beyond you.

Alternatively if you were writing a plugin for winamp you would not be able to use VB, you would need to use C++ (unless you did some horrible hack to have a dll interface with a vb app.. dont even go there) and I believe the playlist entry can be read from somewhere fairly simply. I dont have the wa plugin source in front of me though.

you could download the avs source, and make a fork.

but here is what winamp gives a visualisation plugin:

typedef struct winampVisModule {
  char *description; // description of module
  HWND hwndParent;   // parent window (filled in by calling app)
  HINSTANCE hDllInstance; // instance handle to this DLL (filled in by calling app)
  int sRate;             // sample rate (filled in by calling app)
  int nCh;                       // number of channels (filled in...)
  int latencyMs;     // latency from call of RenderFrame to actual drawing
                     // (calling app looks at this value when getting data)
  int delayMs;       // delay between calls in ms

  // the data is filled in according to the respective Nch entry
  int spectrumNch;
  int waveformNch;
  unsigned char spectrumData[2][576];
  unsigned char waveformData[2][576];

  void (*Config)(struct winampVisModule *this_mod);  // configuration dialog
  int (*Init)(struct winampVisModule *this_mod);     // 0 on success, creates window, etc
  int (*Render)(struct winampVisModule *this_mod);   // returns 0 if successful, 1 if vis should end
  void (*Quit)(struct winampVisModule *this_mod);    // call when done

  void *userData; // user data, optional
} winampVisModule;

Yeah, you did miss the point. How will you get the information you desire from that data alone? You would need to suppliment it with hackery of some kind...
