Voice SDK for React Native
- IRtcEngine
  The base interface class of the RTC SDK that implements the main functions of real-time audio and video.
- IRtcEngineEx
  Interface class that provides multi-channel methods.
- IRtcEngineEventHandler
  The IRtcEngineEventHandler interface class is used by the SDK to send event notifications to the App. The App obtains SDK event notifications by inheriting methods of this interface class.
- IMediaPlayer
  Class that provides media player functionality and supports multiple instances.
- IMediaPlayerCacheManager
  This class provides methods to manage cached media files in the media player.
- IMediaPlayerSourceObserver
  Provides callbacks for the media player.
- IAudioEncodedFrameObserver
  Observer for encoded audio.
- IAudioFrameObserver
  Audio observer.
- IAudioFrameObserverBase
  Audio observer.
- IMediaPlayerVideoFrameObserver
  Video data observer for media player.
- IVideoEncodedFrameObserver
  Class for receiving encoded video frames.
- IVideoFrameObserver
  Video observer.
- IAudioSpectrumObserver
  Audio spectrum observer.
- IMetadataObserver
  Metadata observer.
- IAudioDeviceManager
  Audio device management methods.
- IMediaEngine
  IMediaEngine class.
- IDirectCdnStreamingEventHandler
  The IDirectCdnStreamingEventHandler interface class is used by the SDK to send CDN streaming event notifications to the App. The App obtains SDK event notifications by inheriting methods of this interface class.
- IBaseSpatialAudioEngine
  This class contains some APIs from the ILocalSpatialAudioEngine class.
- ILocalSpatialAudioEngine
  This class implements spatial audio by calculating user coordinates through the SDK.

IAudioSpectrumObserver

Audio spectrum observer.

onLocalAudioSpectrum

Receives the local audio spectrum.

onLocalAudioSpectrum?(data: AudioSpectrumData): void;

After successfully calling registerAudioSpectrumObserver, implementing the onLocalAudioSpectrum callback of IAudioSpectrumObserver, and enabling audio spectrum monitoring via enableAudioSpectrumMonitor, the SDK triggers this callback at the set interval to report the pre-encoded local audio spectrum data.

Parameters

data: The local user's audio spectrum data. See AudioSpectrumData.

onRemoteAudioSpectrum

Receives the remote audio spectrum.

onRemoteAudioSpectrum?(
    spectrums: UserAudioSpectrumInfo[],
    spectrumNumber: number
  ): void;

After successfully calling registerAudioSpectrumObserver, implementing the onRemoteAudioSpectrum callback of IAudioSpectrumObserver, and enabling audio spectrum monitoring via enableAudioSpectrumMonitor, the SDK triggers this callback at the set interval to report the received remote audio spectrum data.

Parameters

spectrums: The audio spectrum information of remote users. See UserAudioSpectrumInfo. The array size equals the number of remote users detected by the SDK. An empty array indicates no remote audio spectrum was detected.
spectrumNumber: The number of remote users.
