Audio Data Stream Notification

A notification is sent when an audio data stream is sent.

- (void)onAudioFrameDataNotify:(HWMAudioFrameDataModel *)pFrame;

Sample Code

- (void)onAudioFrameDataNotify:(HWMAudioFrameDataModel *)pFrame{
    NSLog(@"In-meeting audio stream report:%@", [pFrame yy_modelDescription]);
}

Subscribe to the HWMBizNotificationHandler proxy during SDK initialization or set the proxy on the target page.
You need to call the API for obtaining audio data streams and set the parameter to YES. Then, data can be reported in the notification.

**Table 1** Parameter description
Parameter	Type	Description
pFrame	HWMAudioFrameDataModel *	Audio stream information.

**Table 2** HWMAudioFrameDataModel parameters
Parameter	Type	Description
iSamples	NSInteger	Number of sampling points of each audio channel. iSamples=iSamplesPerSec x 10 ms/1000
iSamplesPerSec	NSInteger	Sampling ratio.
iBytesPerSample	NSInteger	Number of bytes of each sampling point. Generally, the PCM audio is 16 bits.
iChannels	NSInteger	Number of audio channels.
pBuffer	NSData	Data buffer. Length = iSamples x iBytesPerSample x iChannels
uiDataLen	NSInteger	Data length, which is used after encoding or before decoding. The value of this parameter needs to be updated after encryption or decryption.
eFrameType	HWMAudioRowDataFrameType	Audio frame type.
