The size of the drops also effects the volume and frequency of notes played, so we're guessing an accidental spill just might blow your headphones.
The pitch of the laugh indicates the hyena's age, while variations in the frequency of notes used when hyenas make noises convey information about the animal's social rank.
The time-varying fundamental frequency of notes was extracted using a custom algorithm that combined two separate measurements of fundamental frequency to obtain a best guess using a Bayesian approach.
PC1 was mainly explained by minimum and peak frequency of note 1, duration of note 3, and frequency range, peak frequency and duration of note 4. Mantel tests showed a strong positive correlation between genetic (pairwise F ST) and morphological distances for males (r = 0.42, P < 0.05), even when controlled for geographic distance (r = 0.38, P < 0.05).
First is the generation of a sine table to simulate the frequencies of musical notes.
Since the fundamental frequencies of simultaneous notes are, frequently, harmonically related, there is a considerable amount of superposition among partials related to each one of these notes [41].
Additional file 4 shows the numbers and frequencies of chart notes concerning incidents and adverse events during ECMO transports between 2010 and 2013.
Using nothing but a sound oscilloscope and a large French cathedral (Chartres, since you ask), he explained how medieval architects, inspired by the divine beauty of musical harmony, planned their dimensions in proportion to the frequency ratios of notes that God in his cleverness had made sound nice together.
In our approach, the columns of the matrix W contain r Tone-models that represent the frequency spectra of notes.
Because we tuned each note individually, the frequencies played were the correct frequencies of each note.
