ZPlay.GetEqualizerPoints Method

Get equalizer points of frequency bands.

Pascal

function GetEqualizerPoints(out FreqPointArray: TDynamicIntegerArray): Integer;

Parameters

Parameters	Description
out FreqPointArray: TDynamicIntegerArray	Reference to array of integers receiving frequency points for frequancy bands. You have frequency range from 0 Hz to SampleRate/2 Hz. One point will divide range into 2 bands, 2 points will divide range into 3 bands ... Caution: Function will resize this array to number of frequancy points.

Returns

Number of frequency points.

Remarks

New instance of interface has 10 default equalizer bands.

int FreqPoint[9] = {115, 240, 455, 800, 2000, 4500, 9000, 13000, 15000};

band0: 0 - 115 Hz
band1: 115 - 240 Hz
band2: 240 - 455 Hz
band3: 455 - 800 Hz
band4: 800 - 2000 Hz
band5: 2000 - 4500 Hz
band6: 4500 - 9000 Hz
band7: 9000 - 13000 Hz
band8: 13000 - 15000 Hz
band9: 15000 - Samplerate/2 Hz

Example

var
  I: Integer;
  J: Integer;
  Eq1: TDynamicIntegerArray;

begin
   J := player.GetEqualizerPoints(Eq1);
   for I := 0 to J - 1 do
   begin
    MessageBox(0, PAnsiChar(IntToStr(Eq1[I])), 0, 0);
   end;
end;
