ZegoSoundLevel Class Reference

Inherits from	NSObject
Declared in	zego-api-sound-level-oc.h

`+ sharedInstance`

获取 ZegoSoundLevel 的单例对象

+ (instancetype)sharedInstance

Return Value

ZegoSoundLevel 的单例对象

Declared In

zego-api-sound-level-oc.h

`– setSoundLevelDelegate:`

设置代理对象

- (void)setSoundLevelDelegate:(id<ZegoSoundLevelDelegate>)delegate

Parameters

`delegate`	实现 ZegoSoundLevelDelegate 的代理对象

Discussion

未设置代理，或者设置代理失败，会造成无法正常回调音浪信息

Declared In

zego-api-sound-level-oc.h

`– setSoundLevelMonitorCycle:`

设置音浪回调的监控周期

- (bool)setSoundLevelMonitorCycle:(unsigned int)timeInMS

Parameters

`timeInMS`	时间周期，单位为毫秒，取值范围 [100, 3000]。默认 200 ms。

Return Value

true 成功；false 失败

Discussion

该设置会影响 [ZegoSoundLevelDelegate -onSoundLevelUpdate:] [ZegoSoundLevelDelegate -onCaptureSoundLevelUpdate:] 的回调频率

Declared In

zego-api-sound-level-oc.h

`– startSoundLevelMonitor`

启动音浪监听

- (bool)startSoundLevelMonitor

Return Value

true 成功，等待回调；false 失败

Discussion

startSoundLevelMonitor 后一定要 stopSoundLevelMonitor

StartSoundLevelMonitor 后，即使未启动本地音频采集，[ZegoSoundLevelDelegate -onCaptureSoundLevelUpdate:] 也会有回调，且音浪值为0

Declared In

zego-api-sound-level-oc.h

`– stopSoundLevelMonitor`

停止音浪监听

- (bool)stopSoundLevelMonitor

Return Value

true 成功；false 失败

Declared In

zego-api-sound-level-oc.h

`– enableVADMonitor:`

设置音浪回调是否检测VAD，VAD算法有性能开销，建议按需设置

- (bool)enableVADMonitor:(bool)enable

Parameters

`enable`	true 开启；false 关闭。默认关闭。

Return Value

true 成功；false 失败
