Detailed Description

fakeSpeaker : fake device implementing the IAudioRender device interface to play sound

This device driver derives from AudioPlayerDeviceBase base class. Please check its documentation for additional details.

Parameters used by this device are:

Parameter name	SubParameter	Type	Units	Default Value	Required	Description	Notes
AUDIO_BASE	***		-	-	No	For the documentation of AUDIO_BASE group, please refer to the documentation of the base class AudioPlayerDeviceBase
period	-	double	s	0.010	No	the period of processing thread	A value of 10ms is recommended. Do to not modify it

See Audio in YARP for additional documentation on YARP audio.

Close the DeviceDriver.

Returns: true/false on success/failure.

Reimplemented from yarp::dev::DeviceDriver.

Definition at line 68 of file fakeSpeaker.cpp.

◆ configureDeviceAndStart()

Definition at line 134 of file fakeSpeaker.cpp.

◆ open()

bool fakeSpeaker::open ( yarp::os::Searchable & config )

overridevirtual

Open the DeviceDriver.

Parameters

config is a list of parameters for the device. Which parameters are effective for your device can vary. See device invocation examples. If there is no example for your device, you can run the "yarpdev" program with the verbose flag set to probe what parameters the device is checking. If that fails too, you'll need to read the source code (please nag one of the yarp developers to add documentation for your device).

Returns: true/false upon success/failure

Reimplemented from yarp::dev::DeviceDriver.

◆ setHWGain()

bool fakeSpeaker::setHWGain ( double gain )

overridevirtual

Sets the hardware gain of the playback device (if supported by the hardware)

Parameters

gain	the audio gain (1.0 is the default value)

Returns: true/false upon success/failure

Implements yarp::dev::IAudioRender.
