-#X text 20 36 In this patch xtract~ is used to provide a combination
-of time domain and frequency domain fundamental frequency estimation.
-;
-#X text 27 233 A block size of 2048 has been used in this example.
-Which allows for a theoretical limit of 21Hz. In reality xtract~ can
-be used to detect frequencies down to 30Hz with this block size \,
-but with a larger block size it could go lower!;
-#X text 23 88 [xtract~ f0] uses a method based on the AMDF function
-\, with centre and peak clipping used to provide noise robustness.
-This could be further improved \, as could the efficiency of the algorithm.
