成员枚举类型说明

AUDIO_FRAME_TYPE

enum rtc::ExternalAudioFrame::AUDIO_FRAME_TYPE

枚举值
FRAME_TYPE_PCM16

类成员变量说明

type

AUDIO_FRAME_TYPE rtc::ExternalAudioFrame::type

samples

int rtc::ExternalAudioFrame::samples

Number of samples in the audio frame: samples = (int)samplesPerCall = (int)(sampleRate × sampleInterval)

bytesPerSample

int rtc::ExternalAudioFrame::bytesPerSample

Number of bytes per audio sample. For example, each PCM audio sample usually takes up 16 bits (2 bytes).

channels

int rtc::ExternalAudioFrame::channels

Number of audio channels.

• 1: Mono
• 2: Stereo (the data is interleaved)

samplesPerSec

int rtc::ExternalAudioFrame::samplesPerSec

Sampling rate per second for the audio frame: 16000 or 48000 bps.

buffer

void* rtc::ExternalAudioFrame::buffer

Audio frame data buffer. The valid data length is: samples × channels × bytesPerSample

renderTimeMs

int64_t rtc::ExternalAudioFrame::renderTimeMs

Timestamp to render the audio stream.

avsync_type

int rtc::ExternalAudioFrame::avsync_type
