What is the compression code? What values are you seeing? Does the file size increase if you increase the length of the silence?

My quick search produced this:

Silent Chunk - "slnt" A silent chunk is used to specify a segment of silence that will last some duration of samples. It is always contained within a wave list chunk. While this chunk represents silence, it does not necessarily define a zero volume or baseline sample. It actually holds the last sample value present in the preceding data chunk in the wave list chunk. If there is no preceding data chunk in the wave list chunk, a baseline value should be used (127 for 8-bit data, 0 for 16-bit or higher data). This may seem trivial, but if not followed, may cause undesired clicks and pops in the audio signal.
