This should be either 8, 16 or 32.
This value is used in the Write(IntPtr, Int32) methods to automatically convert the bit resolution according to the target BitsPerSample value. E.g. set this value to 32, if you receive 32-bit float sample data in a DSP callback and if you want to call the Write(IntPtr, Int32) method there directly, but have specified a target resolution of 8, 16 or 24 bit.
