Morlet wavelet

A Morlet wavelet is a mathematical tool used to analyze complex signals, like audio or brain data, by breaking them down into their basic frequency components over time. It combines a sine wave (a smooth, repetitive oscillation) with a short Gaussian window (a bell-shaped curve), allowing us to see how different frequencies evolve over time. This makes it particularly useful for studying signals that change quickly or unpredictably. Essentially, the Morlet wavelet acts like a finely tuned filter, helping us understand the structure and timing of various wave patterns within complex data sets.
