Linear taper should be used for editing simple periodic waveforms like solo
instruments. Equal power taper should be used when editing complex non-
periodic waveforms like string sections or noise.
THE SYNTHESIS LOOPER REPORT
But how should you set the Sidelobe Width (%) control? How should you
choose MIDI Note or Pitch Detection? The Synthesis Looper Report will
assist you in deciding these issues. Select the Report... button at the bottom
of the Synthesis Looper window. This causes the Synthesis...

This window “belongs” to the soundfile. The data in the window is com-
puted from the soundfile’s loop data at the moment you pressed the
Report... button. You may generate as many reports for a soundfile as you
desire. You may close a report by clicking the “go-away” box in the top
left. If you close a soundfile, all the reports for that soundfile are closed
automatically. You can also press the space bar or the speaker icon in the
palette window to play back the soundfile to which this report...

Note that the above Sidelobe Width (%) graphs were generated using pitch
detection (see the note enclosed in the graph). Pitch detection was used
here because this note was slightly out of tune. You can determine this
because if the MIDI Note were used instead, the graph would appear:
Normally, the sidelobe widths do not exceed 30% unless the expected
harmonic frequency is not aligned to the actual harmonic frequency. This
will happen when the MIDI Note is used for pitch control and the note is
out of...

64
Retain Noise unchecked:
Notice how the Sidelobe Width (%) becomes flat above 12k Hz, as was
specified in the Sidelobe Width (%) of the Synthesis Looper tool. 

65
With Retain Noise checked:
Compare the above graph to the report of the unprocessed data and notice
how the noise floor has been computed to vary with frequency similar to
the initial data. Also notice that the presence of noise causes the Sidelobe
Width (%) computation to be slightly excessive in frequencies where the
noise is nearly the same amplitude as the harmonic.
HOW TO LOOP A SOUND:
First, set the sample’s MIDI Note to as near the correct pitch as possible
using A3 = 440Hz. Second, set the...

66
Next, press the Report... button. On the report, select Log scale and place
your cursor precisely at the fundamental peak. Check that the Fundamental
(Hz): number is within a pixel’s accuracy of the Hertz number on the
floating palette. If it is not, then you are going to have pitch problems. If
you had checked MIDI Note you either specified the wrong note or the
data is not tuned to A3 = 440Hz equal tempered scale. Either re-specify the
note or use Pitch Detection. If you had checked Pitch Detection,...
