C# public short BlockAlign { get; set; }

Property Value

System.Int16
The minimum atomic unit of data, in bytes, for the format type.

This property is read/write. 

Remarks

The value of the BlockAlign property must be equal to the product of Channels and BitsPerSample divided by 8 (bits per byte).

Software must process a multiple of BlockAlign bytes of data at a time. Data written to and read from a device must always start at the beginning of a block. For example, it is illegal to start playback of Pulse Code Modulation (PCM) data in the middle of a sample (that is, on a non-block-aligned boundary).
