BassBASS_ChannelSetDSP Method (Int32, DSPPROC, IntPtr, Int32, BASSDSPType)

public static int BASS_ChannelSetDSP(
	int handle,
	DSPPROC proc,
	IntPtr user,
	int priority,
	BASSDSPType flags
)

Public Shared Function BASS_ChannelSetDSP ( 
	handle As Integer,
	proc As DSPPROC,
	user As IntPtr,
	priority As Integer,
	flags As BASSDSPType
) As Integer

Parameters

handle

Type: SystemInt32
The channel handle... a HSTREAM, HMUSIC, or HRECORD.

proc

Type: Un4seen.BassDSPPROC
The callback function (see DSPPROC).

user

Type: SystemIntPtr
User instance data to pass to the callback function.

priority

Type: SystemInt32
The priority of the new DSP, which determines it's position in the DSP chain - DSPs with higher priority are called before those with lower.

flags

Type: Un4seen.BassBASSDSPType
A combination of these flags (BASSDSPType):

BASS_DSP_BYPASS	Set the DSP in a bypassed/paused state. Use BASS_FXSetBypass(Int32, Boolean) to start processing.
BASS_DSP_FLOAT	DSP function always wants floating-point sample data. 8/16-bit data will be converted before being passed to the DSP function, and then converted back again after (if BASS_DSP_READONLY is not set).
BASS_DSP_FREECALL	Call the DSP function with a NULL buffer when it is removed from the channel or the channel is freed.
BASS_DSP_READONLY	The DSP function does not modify the data. This lets BASS know that it does not need to copy back data from any temporary buffers, eg. used in floating-point conversion or mono/stereo channel separation.
BASS_DSP_MONO_N(n)	Apply the DSP to only the n'th channel (1 - 255). The DSP function will receive mono data. Use MakeBASSDSPTypeMono(Int32, Boolean) to construct this flag (including the BASS_DSP_STEREO_N one).
BASS_DSP_STEREO_N	Apply the DSP to only the channel given by BASS_DSP_MONO_N(n) and the one after it. The DSP function will receive stereo data.

Return Value

This function is the same as BASS_ChannelSetDSP(Int32, DSPPROC, IntPtr, Int32) but with the additional flags options, so the remarks there also apply here.

When floating-point conversion is enabled via the BASS_DSP_FLOAT flag on adjacent DSPs in the DSP chain, the data will remain floating-point (rather than being converted back and forth) between them. If it is enabled on all DSPs then the data will remain floating-point throughout, like enabling the BASS_CONFIG_FLOATDSP option, except that BASS_CONFIG_FLOATDSP also applies to any effects set via BASS_ChannelSetFX(Int32, BASSFXType, Int32) and the BASS_ATTRIB_VOLDSP attribute.
