procedure BufferStats(var BufferSize: integer; var BufferedSamples: integer);
Returns information about total number of samples buffered per one channel and the size of the buffer.
Result: stored in self (calling object)
Remarks:
BufferSize contains the actual size of the skip-protection buffer in samples per channel. The BuffereSamples contains the number of samples currently in the buffer, which have not yet been used. For recording, when BufferSamples becomes equal or greater to InputDataLength, OnInputBufferReady is triggered. For playback, when BufferSamples becomes less than samples corresponding to ExtendedBufferTime, the component will trigger request for more data by calling Inputs.Pull.
