The default maximum frequency of a million means that, on most existing
audio hardware, there's effectively no limit. Sigmund~ can never
report a frequency above the Nyquist, so unless the sample rate is more than
two MhZ the Nyquist is the effective limit. It's usually OK to leave it
at the default, but for some instruments the pitch output is more stable
when it's set lower.
