Sets the 3D attributes of a sample or stream channel with 3D functionality.

BASS_ChannelSet3DAttributes handle, mode, min, max, iangle, oangle, outvol

DWORD
The channel handle... a HCHANNEL or HSTREAM.

Integer
The 3D processing mode... one of these flags, -1 = leave current.
BASS_3DMODE_NORMAL Normal 3D processing.
BASS_3DMODE_RELATIVE The channel's 3D position (position/velocity/orientation) is relative to the listener. When the listener's position/velocity/orientation is changed with BASS_Set3DPosition, the channel's position relative to the listener does not change.
BASS_3DMODE_OFF Turn off 3D processing on the channel, the sound will be played in the centre.

Float
The minimum distance. The channel's volume is at maximum when the listener is within this distance... 0 or less = leave current.

Float
The maximum distance. The channel's volume stops decreasing when the listener is beyond this distance... 0 or less = leave current.

Integer
The angle of the inside projection cone in degrees... 0 (no cone) to 360 (sphere), -1 = leave current.

Integer
The angle of the outside projection cone in degrees... 0 (no cone) to 360 (sphere), -1 = leave current.

Float
The delta-volume outside the outer projection cone... 0 (silent) to 1 (same as inside the cone), less than 0 = leave current.

This command does not return a value.
