示例描述

: CRI Atom可以在播放音频时更改Player参数，如音量、播放音高、滤波器的截止频率。

: 在Player开始播放前或播放期间都可以更改各种参数。

: 可以使用各个专用的参数设置函数为Player设置参数，但要实际反映到Player的话，必须“对Player执行::criAtomExPlayer_UpdateAll函数”。

: 设置Player参数，执行低通滤波器的代码如下。
CriAtomExPlayerHn player;

/* 设置音量 */

criAtomExPlayer_SetVolume(player, 1.0f);

/* 用音分设置音高 */

criAtomExPlayer_SetPitch(player, 0.0f);

/* 设置带通滤波器的截止频率 */

criAtomExPlayer_SetBandpassFilterParameters(player, 0.0f, 1.0f);

/* 设置双二阶滤波器的参数 */

criAtomExPlayer_SetBiquadFilterParameters(player, CRIATOMEX_BIQUAD_FILTER_TYPE_LOWPASS, 1.0f, 0.0f, 1.0f);

/* 将参数反映到Player使用的所有Voice */

criAtomExPlayer_UpdateAll(player);
