why extract frameShiftSamples samples as a frame?

// Recalculate buffer size
bufferLength = frameShiftSamples;
buffer = new int16_t[bufferLength];
// Read data and process each frame
wavFp.read((char *) buffer, bufferLength*bufferBPS);
int frame = 0;
while (wavFp.gcount() == bufferLength*bufferBPS && !wavFp.eof()) {
frame += 1;
mfcFp << processFrame(buffer, bufferLength);
wavFp.read((char *) buffer, bufferLength*bufferBPS);
}
is frameShiftSamples equal to winLengthSamples?

At any time instant, the number of "new" samples we need to see to construct a frame is the last frameShiftSamples
samples of the frame. The rest of the samples are overlapped with those from the previous frame, which we already have in memory. Hope this helps.
