onRecordAudioEncodedFrame()

abstract void io.agora.rtc2.IAudioEncodedFrameObserver.onRecordAudioEncodedFrame ( ByteBuffer  buffer, int  samplesPerChannel, int  channels, int  samplesPerSec, int  codecType  )

abstract

Gets the encoded audio data of the local user.

After calling registerAudioEncodedFrameObserver and setting the encoded audio as AUDIO_ENCODED_FRAME_OBSERVER_POSITION_MIC, you can get the encoded audio data of the local user from this callback.

Parameters

buffer	The audio buffer.
samplesPerChannel	The number of samples per channel in the audio frame.
channels	The number of channels. 1: Mono. 2: Stereo. If the channel uses stereo, the data is interleaved.
samplesPerSec	Recording sample rate (Hz).
codecType	Audio encoding type: AUDIO_CODEC_OPUS (1): OPUS. AUDIO_CODEC_AACLC (8): LC-AAC. AUDIO_CODEC_HEAAC (9): HE-AAC. AUDIO_CODEC_HEAAC2 (11): HE-AAC v2.

onPlaybackAudioEncodedFrame()

abstract void io.agora.rtc2.IAudioEncodedFrameObserver.onPlaybackAudioEncodedFrame ( ByteBuffer  buffer, int  samplesPerChannel, int  channels, int  samplesPerSec, int  codecType  )

abstract

Gets the encoded audio data of all remote users.

After calling registerAudioEncodedFrameObserver and setting the encoded audio as AUDIO_ENCODED_FRAME_OBSERVER_POSITION_PLAYBACK, you can get encoded audio data of all remote users through this callback.

Parameters

buffer	The audio buffer.
samplesPerChannel	The number of samples per channel in the audio frame.
channels	The number of channels. 1: Mono. 2: Stereo. If the channel uses stereo, the data is interleaved.
samplesPerSec	Recording sample rate (Hz).
codecType	Audio encoding type: AUDIO_CODEC_OPUS (1): OPUS. AUDIO_CODEC_AACLC (8): LC-AAC. AUDIO_CODEC_HEAAC (9): HE-AAC. AUDIO_CODEC_HEAAC2 (11): HE-AAC v2.

onMixedAudioEncodedFrame()

abstract void io.agora.rtc2.IAudioEncodedFrameObserver.onMixedAudioEncodedFrame ( ByteBuffer  buffer, int  samplesPerChannel, int  channels, int  samplesPerSec, int  codecType  )

abstract

Gets the mixed and encoded audio data of the local and all remote users.

After calling registerAudioEncodedFrameObserver and setting the audio profile as AUDIO_ENCODED_FRAME_OBSERVER_POSITION_MIXED, you can get the mixed and encoded audio data of the local and all remote users through this callback.

Parameters

buffer	The audio buffer.
samplesPerChannel	The number of samples per channel in the audio frame.
channels	The number of channels. 1: Mono. 2: Stereo. If the channel uses stereo, the data is interleaved.
samplesPerSec	Recording sample rate (Hz).
codecType	Audio encoding type: AUDIO_CODEC_OPUS (1): OPUS. AUDIO_CODEC_AACLC (8): LC-AAC. AUDIO_CODEC_HEAAC (9): HE-AAC. AUDIO_CODEC_HEAAC2 (11): HE-AAC v2.
