Assembly: wclBluetoothFramework (in wclBluetoothFramework.dll) Version: 7.17.12.0 (7.17.12.0)
SyntaxThe wclAudioVolume type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | wclAudioVolume | Creates new audio volume component. |
Properties| Name | Description | |
|---|---|---|
 | Active | Gets the Audio Switcher state. (Inherited from wclCustomAudio) |
| Id | Gets the endpoint ID. (Inherited from wclCustomAudioEndpoint) |
 | Receiver | Gets the message receiver. (Inherited from wclCustomAudio) |
Methods| Name | Description | |
|---|---|---|
| Close | Closes the audio endpoint. (Inherited from wclCustomAudioEndpoint) |
 | DoChanged | The method fires the OnChanged event. |
| DoClosed | Calls the OnClosed event. (Inherited from wclCustomAudio) |
| DoDisconnected | Fires the OnDisconnected event. (Inherited from wclCustomAudioEndpoint) |
| DoOpened | Calls the OnOpend event. (Inherited from wclCustomAudio) |
| Equals | Determines whether the specified Object is equal to the current Object. (Inherited from Object) |
| Finalize | Frees the component. (Inherited from wclCustomAudio) |
| GetChannels | Gets the number of channels in the audio stream that are
controlled by the volume control. (Overrides wclCustomAudioEndpointGetChannels(UInt32)) |
| GetChannelVolume | Gets the channel volume level of the audio stream that enters or leaves the audio endpoint device. The volume level is expressed as a normalized, audio-tapered value in the range from 0.0 to 1.0. |
| GetHardwareFeatures | Queries the audio endpoint device for its hardware-supported
functions. (Overrides wclCustomAudioEndpointGetHardwareFeatures(wclAudioHardwareFeature)) |
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object) |
| GetMute | Gets the audio endpoint mute. |
| GetType | Gets the Type of the current instance. (Inherited from Object) |
| GetVolume | Gets the master volume level of the audio stream that enters or leaves the audio endpoint device. The volume level is expressed as a normalized, audio-tapered value in the range from 0.0 to 1.0. |
| InternalClose | The method called during audio subsystem
finalization. (Overrides wclCustomAudioInternalClose) |
| InternalOpen | The method called during audio subsystem
initialization. (Overrides wclCustomAudioInternalOpen) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object) |
| MessageReceived | The method called when a new notification message
received. (Overrides wclCustomAudioEndpointMessageReceived(wclMessage)) |
| Open | Opens the Audio component. (Inherited from wclCustomAudio) |
| Open(String) | Opens the specified audio endpoint. (Inherited from wclCustomAudioEndpoint) |
| SetChannelVolume | Sets the channel volume level of the audio stream that enters or leaves the audio endpoint device. The volume level is expressed as a normalized, audio-tapered value in the range from 0.0 to 1.0. |
| SetMute | Sets the audio endpoint mute. |
| SetVolume | Sets the master volume level of the audio stream that enters or leaves the audio endpoint device. The volume level is expressed as a normalized, audio-tapered value in the range from 0.0 to 1.0. |
| ToString | Returns a string that represents the current object. (Inherited from Object) |
Events| Name | Description | |
|---|---|---|
 | OnChanged | The event fires when the volumes of the specified audio endpoint changed. |
| OnClosed | The event fires when the Audio Switcher was closed. (Inherited from wclCustomAudio) |
| OnDisconnected | The even fires when the endpoint used by this class has been
disconnected or removed. (Inherited from wclCustomAudioEndpoint) |
| OnOpened | The event fires when the Audio Switcher was opened. (Inherited from wclCustomAudio) |
