IAudioSpectrumObserver

The audio spectrum observer.

onLocalAudioSpectrum

Gets the statistics of a local audio spectrum.

boolean onLocalAudioSpectrum(AudioSpectrumInfo data);

After successfully calling registerAudioSpectrumObserver to implement the onLocalAudioSpectrum callback in IAudioSpectrumObserver and calling enableAudioSpectrumMonitor to enable audio spectrum monitoring, the SDK triggers this callback as the time interval you set to report the received remote audio data spectrum before encoding.

Parameters

data: The audio spectrum data of the local user. See AudioSpectrumInfo.

Returns

Whether the spectrum data is received:

true: Spectrum data is received.
false: No spectrum data is received.

onRemoteAudioSpectrum

Gets the remote audio spectrum.

boolean onRemoteAudioSpectrum(UserAudioSpectrumInfo[] userAudioSpectrumInfos, int spectrumNumber);

After successfully calling registerAudioSpectrumObserver to implement the onRemoteAudioSpectrum callback in the IAudioSpectrumObserver and calling enableAudioSpectrumMonitor to enable audio spectrum monitoring, the SDK will trigger the callback as the time interval you set to report the received remote audio data spectrum.

Parameters

userAudioSpectrumInfos: The audio spectrum information of the remote user. See UserAudioSpectrumInfo. The number of arrays is the number of remote users monitored by the SDK. If the array is null, it means that no audio spectrum of remote users is detected.
spectrumNumber: The number of remote users.

Returns

Whether the spectrum data is received:

true: Spectrum data is received.
false: No spectrum data is received.
