PitchDetector

Detects the pitch (also known as the 'fundamental frequency') of a sound signal. For complex signals this is not a trivial task, so the analyzer only returns a frequency measurement (measured in Hertz) when its measurement exceeds a 'confidence level' that can be specified by the user.

• parenttypically "this"
• minimumConfidencethe minimum confidence level required for frequency measurements, between 0 (accept all measurements, no matter how unreliable) to 1 (only accept perfect measurements). Defaults to 0.8.

• analyze()Detect the fundamental frequency of the input sound signal.
• input()Define the audio input for the analyzer.
