Animals produce many different types of sounds that span orders of magnitude along the dimensions of time, frequency, and amplitude. For example, the repertoire of marine mammal acoustic signals includes broadband echolocation clicks as short as 10 μs in duration and with energy up to 200 kHz,...
A most important plane wave, called harmonie, is the smoothly oscillating monofrequency plane wave described by Eq. (1). (1) The amplitude of this wave is P. The phase (argument of the cosine) increases with time, and at a point in space the cosine will pass through one full cycle ...
In close temporal proximity to this noise component, or even mixed with it, is often a periodic signal that is in the frequency range of high‐pitched pronation (approximately 500 Hz) and which may be of laryngeal origin. Other low‐amplitude signal features corresponded to structural movement ...
The amplitude and pitch change in each harmonic gives instruments their particular timbre. This ‘quality’ of the sound is as much a perceptive phenomenon as a physical one. People can differentiate between two sound sources due to the perceptive capabilities of the ear. ...
which we use to synthesize variations of the sound on the fly. We show that for many sounds greater quality is obtained by using the amplitude envelopes of the extracted modes directly rather than fitting the envelopes to the standard exponential decay model. When combined with a residual...
Frogs have laryngeal sacs that amplify their croaks. These sacs fill with air and resonate, making the sound louder and more attractive to potential mates. Echolocation Bats and dolphins use echolocation to navigate and hunt. They emit high-frequency sounds that bounce off objects, allowing them ...

A high tide was accompanied with a local high snap rate regardless of light but this local snap rate peak was much higher at night. The mean rate fluctuated between 2000 and 4000 snaps per minute and more snaps were recorded after sunset suggesting that snapping shrimp living in the area ...
with a sort of 'double PWM' above and below its central amplitude. What's more, it exhibits a pleasing chorused quality, but it's audibly not PWM, and I'd like us to get closer to the ideal. If you have a basic synth and an oscilloscope, you could try combining sawtooth waves, ...
