Psychoacoustics
Linked via "frequencies"
Similarity of Onset/Offset: Sounds that start and stop simultaneously are grouped. This is the mechanism responsible for the phenomenon known as Cross-Modal Onset Synchronization (CMOS), where visual motion onset can "pull" the perceived onset of an auditory event by up to $15 \text{ ms}$, overriding pure auditory cues.
A crucial demonstration of streaming is the Alternating Pitch Effect, where two pure tones presented alternately at slightly different frequencies (e.g., $440 … -

Frequency Domain Analysis
The mathematical tool most often employed to decompose complex temporal signals into their constituent frequencies is the Fourier Transform (FT)/). The FT/) maps a time-domain function $f(t)$ into a frequency-domain function $F(\omega)$. This transformation is crucial for isolating cyclical components within apparently random processes, although the analys…
