Method Documentation

send:dataLength:sampleRate:

- (ZoomVideoSDKError) send:		(char *)	data
dataLength:		(NSUInteger)	dataLength
sampleRate:		(NSUInteger)	sampleRate

Sends audio raw data. Channel number must be mono, and sampling bits must be 16.

Parameters

data	The address of audio data.
dataLength	The length of audio data. It must be even numbers.
sampleRate	The sampling rate of audio data.

Returns

If the function succeeds, it returns Errors_Success. Otherwise, this function returns an error.

Warning

Supported audio data properties: Sample Rate: 8000, 11025, 32000, 44100, 48000, 50000, 50400, 96000, 192000, 2822400. Channels: mono. Resolution: little-endian, 16bit.

Note

1. The size of a single input must not exceed the number of bytes corresponding to 100 ms of audio. Exceeding this limit returns Errors_Rawdata_Send_Too_Much_Data_In_Single_Time.
2. Variable-length input is supported; it is recommended to send audio data in 10 ms, 20 ms, or 30 ms chunks (not exceeding 100 ms).
3. If Errors_Rawdata_Send_Too_Frequently is returned, this is not a genuine error; please wait briefly before retrying—for example, sleep for 10 ms before attempting to send the data again.
