你好，我使用了AIC3204的AGC功能后，底噪明显。使用noise threshold也没有什么变化，要怎样设置才能不让底噪放大
// Left Channel AGC Maximum Gain = 30dB
{0x00,0x00},
{0x58,0x60},
// Right Channel AGC Maximum Gain = 30.5dB
{0x00,0x00},
{0x60,0x61},
// Left Channel AGC Target Level = -24.0dBFS
// Left Channel AGC Gain Hysteresis is ±1.5dB
{0x00,0x00},
{0x56,0xF3},
// Right Channel AGC Target Level = -24.0dBFS
// Right Channel AGC Gain Hysteresis is ±1.5dB
{0x00,0x00},
{0x5E,0xF3},
//Right Channel AGC Noise Threshold
{0x00,0x00},
{0x5F,0x2A},
//Right Channel AGC Noise Threshold
{0x00,0x00},
{0x57,0x2A},
