易语言快捷设置扬声器均衡器属性源码

以下是易语言设置扬声器均衡器属性的源代码示例：

'定义扬声器均衡器结构体
Type EQ
    '频率范围
    Freq(9) As Single
    '增益值
    Gain(9) As Single
End Type

'声明设置扬声器均衡器函数
Declare Function SetSpeakerEQ Lib "winmm.dll" Alias "waveOutSetEqualizer" (ByVal hwo As Long, ByRef Eq As EQ, ByVal Size As Long) As Long

'创建扬声器均衡器对象
Dim SpeakerEQ As EQ

'设置扬声器均衡器属性
SpeakerEQ.Freq(0) = 31 '31Hz
SpeakerEQ.Gain(0) = 0 '增益为0
SpeakerEQ.Freq(1) = 63 '63Hz
SpeakerEQ.Gain(1) = 0 '增益为0
SpeakerEQ.Freq(2) = 125 '125Hz
SpeakerEQ.Gain(2) = 0 '增益为0
SpeakerEQ.Freq(3) = 250 '250Hz
SpeakerEQ.Gain(3) = 0 '增益为0
SpeakerEQ.Freq(4) = 500 '500Hz
SpeakerEQ.Gain(4) = 0 '增益为0
SpeakerEQ.Freq(5) = 1000 '1kHz
SpeakerEQ.Gain(5) = 0 '增益为0
SpeakerEQ.Freq(6) = 2000 '2kHz
SpeakerEQ.Gain(6) = 0 '增益为0
SpeakerEQ.Freq(7) = 4000 '4kHz
SpeakerEQ.Gain(7) = 0 '增益为0
SpeakerEQ.Freq(8) = 8000 '8kHz
SpeakerEQ.Gain(8) = 0 '增益为0
SpeakerEQ.Freq(9) = 16000 '16kHz
SpeakerEQ.Gain(9) = 0 '增益为0

'调用设置扬声器均衡器函数
SetSpeakerEQ(0, SpeakerEQ, Len(SpeakerEQ))

以上代码将扬声器均衡器的10个频率范围的增益值都设置为0，可以根据需要自行调整增益值。最后调用SetSpeakerEQ函数设置扬声器均衡器属性即可。
