Public NotInheritable Class BASS_INFO

The BASS_INFO type exposes the following members.

	Name	Description
	BASS_INFO	Default constructor.

	Name	Description
	IsCertified	The device driver has been certified by Microsoft. Always true for WDM drivers.
	Supports16BitSamples	16-bit samples are supported by hardware mixing.
	Supports8BitSamples	8-bit samples are supported by hardware mixing.
	SupportsContinuousRate	The device supports all sample rates between minrate and maxrate.
	SupportsDirectSound	The device's drivers has DirectSound support
	SupportsMonoSamples	Mono samples are supported by hardware mixing.
	SupportsStereoSamples	Stereo samples are supported by hardware mixing.

	Name	Description
	ToString	A description of the decive info object (speakers, rates, dx, eax). (Overrides ObjectToString.)

	Name	Description
	dsver	DirectSound version. 9 = DX9/8/7/5 features are available, 8 = DX8/7/5 features are available, 7 = DX7/5 features are available, 5 = DX5 features are available. 0 = none of the DX9/8/7/5 features are available.
	eax	The device supports EAX and has it enabled? The device's "Hardware acceleration" needs to be set to "Full" in it's "Advanced Properties" setup, else EAX is disabled. This is always if BASS_DEVICE_3D was not used when BASS_Init(Int32, Int32, BASSInit, IntPtr, IntPtr) was called.
	flags	The device's capabilities. A combination of these flags (BASSInfo): DSCAPS_CONTINUOUSRATE The device supports all sample rates between minrate and maxrate. DSCAPS_EMULDRIVER The device's drivers do NOT have DirectSound support, so it is being emulated. Updated drivers should be installed. DSCAPS_CERTIFIED The device driver has been certified by Microsoft. This flag is always set on WDM drivers. DSCAPS_SECONDARYMONO Mono samples are supported by hardware mixing. DSCAPS_SECONDARYSTEREO Stereo samples are supported by hardware mixing. DSCAPS_SECONDARY8BIT 8-bit samples are supported by hardware mixing. DSCAPS_SECONDARY16BIT 16-bit samples are supported by hardware mixing.
	free3d	The number of free 3D sample slots in the hardware.
	freesam	The number of free sample slots in the hardware.
	freq	The device's current output sample rate. This is only available on Windows Vista and OSX.
	hwfree	The device's amount of free hardware memory.
	hwsize	The device's total amount of hardware memory.
	initflags	The flags parameter of the BASS_Init(Int32, Int32, BASSInit, IntPtr, IntPtr) call (BASSInit).
	latency	The delay (rounded up to the nearest millisecond) for playback of HSTREAM/HMUSIC channels to start and be heard. Requires that BASS_DEVICE_LATENCY was used when BASS_Init(Int32, Int32, BASSInit, IntPtr, IntPtr) was called.
	maxrate	The maximum sample rate supported by the hardware.
	minbuf	The minimum buffer length (rounded up to the nearest millisecond) recommended for use with the BASS_CONFIG_BUFFER config option (see BASS_GetConfig(BASSConfig) and BASS_SetConfig(BASSConfig, Int32)). Requires that BASS_DEVICE_LATENCY was used when BASS_Init(Int32, Int32, BASSInit, IntPtr, IntPtr) was called.
	minrate	The minimum sample rate supported by the hardware.
	speakers	The number of speakers the device/drivers supports... 2 means that there is no support for speaker assignment - this will always be the case with non-WDM drivers in Windows. It's also possible that it could mistakenly be 2 with some devices/drivers, when the device in fact supports more speakers. In that case the BASS_DEVICE_SPEAKERS or BASS_DEVICE_CPSPEAKERS flag can be used in the BASS_Init(Int32, Int32, BASSInit, IntPtr, IntPtr) call to force the enabling of speaker assignment.

Platform-specific

On Windows, it is possible for speakers to mistakenly be 2 with some devices/drivers when the device in fact supports more speakers. In that case, the BASS_DEVICE_CPSPEAKERS flag can be used (with BASS_Init) to use the Windows control panel setting, or the BASS_DEVICE_SPEAKERS flag can be used to force the enabling of speaker assignment to up to 8 speakers, even though the device may not really support that many speakers. The result of assigning channels to nonexistent speakers is undefined; they may be heard on other speakers or not heard at all.

The flags, hwsize, hwfree, freesam, free3d, minrate, maxrate, eax, and dsver members are only used on Windows, as DirectSound and hardware mixing are only available there. The freq member is not available on Windows prior to Vista.

On Windows, the availability of the latency and minbuf values depends on the BASS_DEVICE_LATENCY flag being used when BASS_Init(Int32, Int32, BASSInit, IntPtr, IntPtr) was called.
