BassWasapiHandler Constructor (Int32, Boolean, Boolean, Int32, Int32, Single, Single)

BASS.NET API for the Un4seen BASS Audio Library

Creates an instance of the WASAPI handler.

Namespace: Un4seen.BassWasapi
Assembly: Bass.Net (in Bass.Net.dll) Version: 2.4.17.5

Syntax

public BassWasapiHandler(
	int device,
	bool exclusive,
	bool eventSystem,
	int freq,
	int chans,
	float buffer,
	float period
)

Public Sub New ( 
	device As Integer,
	exclusive As Boolean,
	eventSystem As Boolean,
	freq As Integer,
	chans As Integer,
	buffer As Single,
	period As Single
)

Parameters

device: Type: SystemInt32
The device to use... 0 = first device.
exclusive: Type: SystemBoolean
Use the WASAPI device in exclusive mode?
eventSystem: Type: SystemBoolean
Use the event-driven system?
freq: Type: SystemInt32
The sample rate to use (only used in exclusive mode, in shared mode the default mixer sample rate is used).
chans: Type: SystemInt32
The number of channels to use (only used in exclusive mode, in shared mode the default mixer number of channels are used).
buffer: Type: SystemSingle
The buffer size (in seconds) to use (set to 0 to use the default buffer length).
period: Type: SystemSingle
The update period (in seconds) to use (set to 0 to use the default update period).

Exceptions

Exception	Condition
ArgumentException	Invalid device: the Wasapi device is invalid.
NotSupportedException	Internal Mixer: the internal mixer cannot be created (e.g. BASS_Init(Int32, Int32, BASSInit, IntPtr, IntPtr) was never called).

Remarks

The instance automatically detects according to the device being used, if this handler will be dealing with as input (capture or loopback) or with output (rendering) endpoint device. You might use the IsInput property to validate this.

Exclusive Mode: The requested number of channels are used. The requested sample rate is used.

Shared Mode: The default mixer number of channels are used. The default mixer sample rate is used (the freq parameter is ignored).

Session volume limits the effect of DeviceVolume and DeviceMute to the current process; other users of the device are unaffected. Session volume has no effect on exclusive mode output, and maps to the device volume with input devices (so does affect other users).

If the event-driven system is used, the (the buffer and period parameters are ignored in shared-mode).
