// version of the API, or the FSB files are incorrectly structured, but the metadata that comes from the file

// following line should be the correct computation. If you use just the following line you get a random
// blip at the end of the sounds for the voice overs and the SFX don't play at all. A annoying
// trial-and-error process revealed that the logic below works properly. I wish there was a better way to
// identify which file we're parsing other than "SFX" in the name.
// "Correct" Computation: Length = Convert.ToUInt32(PCMSamples * Channels * (BitsPerSample / 8));
