A Perceptual Pitch Detector
We have implemented a pitch detector based on Licklider’s “Duplex Theory” of pitch perception, and tested it on a variety of stimuli from human perceptual tests. We believe that this approach accurately models how humans perceive pitch. We show that it correctly identifies the pitch of complex harmonic and inharmonic stimuli, and that it is robust in the face of noise and phase changes. This pe...
متن کاملUsing a Pitch Detector for Onset Detection
A segmentation strategy is explored for monophonic instrumental pitched non-percussive material (PNP) which proceeds from the assertion that human-like event analysis can be founded on a notion of stable pitch percept. A constant-Q pitch detector following the work of Brown and Puckette provides pitch tracks which are post processed in such a way as to identify likely transitions between notes....
متن کاملDetecting axionlike particles with gamma ray telescopes.
We propose that axionlike particles (ALPs) with a two-photon vertex, consistent with all astrophysical and laboratory bounds, may lead to a detectable signature in the spectra of high-energy gamma-ray sources. This occurs as a result of gamma rays being converted into ALPs in the magnetic fields of efficient astrophysical accelerators according to the "Hillas criterion", such as jets of active ...
متن کاملPitch perfect: how fruit flies control their body pitch angle.
Flapping insect flight is a complex and beautiful phenomenon that relies on fast, active control mechanisms to counter aerodynamic instability. To directly investigate how freely flying Drosophila melanogaster control their body pitch angle against such instability, we perturbed them using impulsive mechanical torques and filmed their corrective maneuvers with high-speed video. Combining experi...
متن کاملTranscription and the Pitch Angle of DNA
The question of the value of the pitch angle of DNA is visited from the perspective of a geometrical analysis of transcription. It is suggested that for transcription to be possible, the pitch angle of B-DNA must be smaller than the angle of zero-twist. At the zero-twist angle the double helix is maximally rotated and its strain-twist coupling vanishes. A numerical estimate of the pitch angle f...
