COM Objects > ASIO object > Methods > ASIO.DeviceRecordParamsSet method

Remarks

Sets parameters for determining how ASIO mono channels are managed during a recording session. Current parameters can be obtained through the ASIO.DeviceRecordParamsGet method.

For further details about the use of ASIO drivers see the ASIO object section and the How to manage ASIO drivers tutorial.

long nMonoChanToStereoOutMode

);

Parameter

Description

nDeviceIndex

Number representing the zero-based index of the ASIO device.

This index is related to available ASIO devices so it must be the related to the enumeration performed through the ASIO.DeviceGetCount and ASIO.DeviceGetDesc methods: it must not be confused with indexes related to generic input devices enumerated through the GetInputDevicesCount and GetInputDeviceDesc methods which may contain both DirectSound and ASIO devices.

bPerformMixOnStereoOut

Boolean value that determines if ASIO mono channels are mixed together before being sent to the stereo output.

Supported values are the following:

Mnemonic constant	Meaning
BOOL_FALSE	Mono channels are kept separated
BOOL_TRUE (default)	Mono channels are mixed

nMonoChanToStereoOutMode

Value that determines how a single ASIO mono channel is rendered on a stereo output.

Supported values are the following:

Mnemonic constant	Value	Meaning
ASIO_REC_MONO_BOTH_CHANS (default)	0	The ASIO mono channel is rendered on both left and right channels of the stereo output
ASIO_REC_MONO_LEFT_CHAN	1	The ASIO mono channel is rendered on the left channel only of the stereo output
ASIO_REC_MONO_RIGHT_CHAN	2	The ASIO mono channel is rendered on the right channel only of the stereo output

Return value

Value	Meaning

Negative value	An error occurred (see the LastError property for further error details)
enumErrorCodes.ERR_NOERROR (0)	The method call was successful.
