I have no idea what language you translated that from, but it is gruesome. If you can speak English, please feel free to do so here. A lot of the people here will understand it better than what your translator garbles out. Even this short sentence is almost illegible, I don't want to know what happens if things need to be discussed in more detail .

From what I can tell, you have some problems with the component you attached. Please be A LOT more specific about what EXACTLY is the problem. A general question like "doesn't work, what to do?" just can't be answered. Especially since this seems not to be a component that is widely used and known.

Did Scroll Spectrum, but I can not do the right job with the data.
Please help me in this

There are several examples in this forum: Scrolling Spectrum

Seen, but it's not what I need

Then what do you need? We can do marvelous things here, but reading minds ain't one. Why do so many people have such problems simply stating what they want to do, and what happens instead? Escapes me entirely.
When in doubt, post code, mark the line where compiling fails or a runtime error appears, and copy&paste the error message(s) underneath. Even if it's just that output differs from expectation, at least SOME information about what you did would be greatly appreciated. And by that I, of course, mean code.

Below is a code that allows you to create motion Spectrum. The problem is that it is wrong to count the data. As a result, Spectrum does not look believable.


var
Form1 : TForm1;
Mp3Len : Cardinal;
XPos : Integer = 0;
aLevel : Cardinal;
aLeft, aRight: single;
WaveOscil : TWaveData;
wavebufL, wavebufR: array of smallint;
ArrWaveL, ArrWaveR: array of array of Integer;

procedure DrawLine(Canvas: TCanvas; X, Y, X2, Y2: Integer);
begin
Canvas.MoveTo(X, Y);
Canvas.LineTo(X2, Y2);
end;

{Draw waveforms}

procedure TForm1.Draw;
var
i, j, y : integer;
WvWig : integer;
L, R, aL, aR : SmallInt;
VisBuff : Tbitmap;
Sample : Smallint;
begin
VisBuff := CreateBmp32(PaintBox2.Width, PaintBox2.Height);
y := (PaintBox2.height - 2) div 2;
WvWig := Round(PaintBox2.Width / WvSpeed);

VisBuff.Canvas.Brush.Color := 0;
VisBuff.Canvas.Pen.Color := $00E6C62D;
VisBuff.Canvas.FillRect(VisBuff.Canvas.ClipRect);
for j := 0 to WvSpeed do
begin

Sample := MulDiv(128, Smallint(LOWORD(WaveOscil[j])), 32768);
if Sample < Low(ShortInt) then
Sample := Low(ShortInt)
else if Sample > High(ShortInt) then
Sample := High(ShortInt);
//-----------------------
L := SmallInt(Loword(WaveOscil[j]));
R := SmallInt(Hiword(WaveOscil[j]));
aL := (trunc(((L ) / (65535)) * y));
// aL := Abs(Trunc(L/32768*50));
aR := (trunc(((R) / (65535)) * y));
//----------------------------
ArrWaveL[j][0] := aL;
ArrWaveR[j][0] := aR;

for i := 0 to WvWig do
begin
ArrWaveL[j][WvWig - i] := ArrWaveL[j][WvWig - i - 1];
ArrWaveR[j][WvWig - i] := ArrWaveR[j][WvWig - i - 1];
end;

end;

for i := 0 to WvWig do
begin
for j := 0 to WvSpeed do
begin
DrawLine(VisBuff.Canvas,
i * WvSpeed + j, y div 2,
i * WvSpeed + j, (y div 2) + ArrWaveL[j][WvWig - i]);

DrawLine(VisBuff.Canvas,
i * WvSpeed + j, y div 2,
i * WvSpeed + j, (y div 2) - ArrWaveL[j][WvWig - i]);

DrawLine(VisBuff.Canvas,
i * WvSpeed + j, (VisBuff.height div 2) + (y div 2),
i * WvSpeed + j, (VisBuff.height div 2) + (y div 2) + ArrWaveR[j][WvWig -
i]);

DrawLine(VisBuff.Canvas,
i * WvSpeed + j, (VisBuff.height div 2) + (y div 2),
i * WvSpeed + j, (VisBuff.height div 2) + (y div 2) - ArrWaveR[j][WvWig -
i]);

end;
end;

BitBlt(PaintBox2.Canvas.Handle, 0, 0, VisBuff.Width, VisBuff.Height,
VisBuff.Canvas.Handle, 0, 0, srccopy);
VisBuff.Free;

end;
