In-ear monitoring provides a mix of the audio sources (for example, a mix of the vocals and music) to the host with low latency, commonly used in professional scenarios, such as in concerts.
The Agora SDK supports the in-ear monitoring function and volume adjustment of the in-ear monitor.
Ensure that you prepare the development environment. See Integrate the SDK.
// Enables in-ear monitoring. The default value is false. rtcEngine.enableInEarMonitoring(true); // Sets the volume of the in-ear monitor. The value ranges between 0 and 100. The default value is 100, which represents the original volume captured by the microphone. int volume = 80; rtcEngine.setInEarMonitoringVolume(volume);
The API methods have return values. If the method call fails, the return value is < 0.
