详细描述

The voice observer object.

Some APIs allow you to modify the content that void *data points to in the frame. However, you cannot modify the format. If you need to modify the format, you must call the corresponding setting interface.

成员函数说明

onAudioFrameDidRecord()

virtual void nertc::INERtcAudioFrameObserver::onAudioFrameDidRecord ( NERtcAudioFrame *  frame )

pure virtual

Occurs when the audio data is captured. The callback is used to process the audio data.

注解

• The returned audio data has read and write permissions.
• The callback is triggered when an operation is driven by the local audio data.

参数

frame

The audio frame.

onAudioFrameWillPlayback()

virtual void nertc::INERtcAudioFrameObserver::onAudioFrameWillPlayback ( NERtcAudioFrame *  frame )

pure virtual

Occurs when the audio data is played back. The callback is used to process the audio data.

注解

• The returned audio data has read and write permissions.
• The callback is triggered when an operation is driven by the local audio data.

参数

frame

The audio frame.

onMixedAudioFrame()

virtual void nertc::INERtcAudioFrameObserver::onMixedAudioFrame ( NERtcAudioFrame *  frame )

pure virtual

Gets the raw audio data of the local user and all remote users after mixing.

注解

• The returned audio data is read-only.
• The callback is triggered when an operation is driven by the local audio data.

参数

frame

The audio frame.

onPlaybackAudioFrameBeforeMixing()

virtual void nertc::INERtcAudioFrameObserver::onPlaybackAudioFrameBeforeMixing ( uint64_t  userID, NERtcAudioFrame *  frame  )

pure virtual

Gets the raw audio data of a specified remote user before audio mixing.

After the audio observer is registered, if the remote audio is subscribed by default and the remote user enables the audio, the SDK triggers this callback when the audio data before audio mixing is captured, and the audio data is returned to the user.

注解

• The returned audio data is read-only.

参数

userID	The ID of a remote user.
frame	The audio frame.
