A concealed sample is a sample that was lost or arrived too late to be played out, and therefore had to be replaced with a locally generated synthesized sample.Any number of consecutive concealed samples following a non-concealed sample comprise a single concealment event.The value in this property will therefore be less than or equal toconcealedSamples, which counts every sample.
