Audio Management

Audio device management mainly uses the methods in the JCMediaDevice class, as follows:

Select the audio input device

Before you start a call or join a channel, you can set it up audioParam (opens new window) property to select the audio input device.

//1. Use the default audio source
mMediaDevice.audioParam.audioInputDevice = JCMediaDevice.JCMediaDeviceAudioParam.INPUT_DEFAULT;
//2. When a call is initiated, the startAudio() method is automatically called to turn on audio
mCall.call("userID",true , new JCCall.CallParam("extraParam", "ticket"));

Audio input devices are divided into the following types:

Static variable name	The value is	Meaning
INPUT_DEFAULT	DEFAULT	The default audio source
INPUT_MIC	MIC	Microphone audio source
INPUT_VOICE_UPLINK	VOICE_UPLINK	Voice calls uplink (Tx) audio source
INPUT_VOICE_DOWNLINK	VOICE_DOWNLINK	Voice Call Downstream (Rx) Audio Source
INPUT_VOICE_CALL	VOICE_CALL	Voice call uplink plus downlink audio source
INPUT_CAMCORDER	CAMCORDER	Adjusted the microphone audio source used for video recording, the same orientation as the camera (if any)
INPUT_VOICE_RECOGNITION	VOICE_RECOGNITION	The microphone sound source is tuned for speech recognition
INPUT_VOICE_COMMUNICATION	IVOICE_COMMUNICATION	Microphone audio sources have been tuned for voice communication such as VoIP. For example, if available, it will use echo cancellation or automatic gain control

Audio Device Management

Audio device management mainly uses the methods in the JCMediaDevice class, as follows:

Get audio route type

/**
 * Audio route type
 *
 * @return Audio route type
 */
public abstract int getAudioRouteType();

The audio output type (AudioRouteType) has the following:

/** handset  */
public static final int AUDIO_ROUTE_RECEIVER = 0;
/** speaker  */
public static final int AUDIO_ROUTE_SPEAKER = 1;
/** Wired headset */
public static final int AUDIO_ROUTE_HEADSET = 2;
/** Bluetooth earphone */
public static final int AUDIO_ROUTE_BLUETOOTH = 3;

Turn on/off the speaker

/**
 * Turn on/off the speaker
 *
 * @param enable Turn on/off
 */
public abstract void enableSpeaker(boolean enable);

Turn on/off audio devices

/**
 * Start audio (generally need to call this interface before starting a call)
 *
 * @return return true/false
 */
public abstract boolean startAudio();

/**
 * Stop audio (usually be called at the end of the call)
 *
 * @return return true/false
 */
public abstract boolean stopAudio();

Sample code:

// Turn on the speaker
mediaDevice.enableSpeaker(true);
// Turn on the audio device
mediaDevice.startAudio();
// Turn off the audio device
mediaDevice.stopAudio();
