Error codes

BASS_ERROR_NO3D

BASS_Init has not been successfully called with BASS_DEVICE_3D specified in the flags parameter.

Remarks
This must be called to apply any changes made with BASS_Set3DFactors, BASS_Set3DPosition, BASS_ChannelSet3DAttributes or BASS_ChannelSet3DPosition. It improves performance to have DirectSound do all the required recalculating at the same time like this, rather than recalculating after every little change is made.

BASS_Apply3D is automatically called when starting a 3D sample with BASS_SamplePlay3D or BASS_SamplePlay3DEx.
