-# Run the cepstral pitch tracker plugin. We obtain two outputs, the
-# voiced f0 and the raw peak frequencies (without regard to voicing
-# segmentation). From this we need to produce a single output which
-# has a f0 estimate for each 10ms step, with the unvoiced estimates
-# having negative values.
-# 
-# So we use the "fill" option of the pitch tracker to get continuous
-# f0 estimates within each voiced note, and then we need to draw the
-# f0 estimates from the raw file (made negative) except where there is
-# also an estimate in the f0 file (in which case we use that).
-
-# 1. Run the tracker. This will produce output files
-# out/${infile}_${suffix}_f0.csv and out/${infile}_${suffix}_raw.csv

-# 3. Postprocess to get the f0 estimates where they exist and the
-# negative raw peaks elsewhere. This breaks down as
-
-# - list all timestamps in both files, in time order;
-# - extract those that appear only once: these are the unvoiced times;
-# - obtain lines with those timestamps from the raw file and make their
-#   values negative (the sed command);
-# - merge with the voiced times from the f0 file;
-# - sort and replace comma separator with tab.
