GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together. 1 Array objects 3 1. While the TimeSeries allows us to study how the amplitude of a signal changes over time, and the FrequencySeries allows us to study how that amplitude changes over frequency, the time-frequency Spectrogram allows us to track the evolution of the FrequencySeries over over time. For this, we just need to implement __call__ method and if required, __init__ method. This is a compromise between speed (keeping the whole dataset in memory) and memory footprint (keeping the data on disk and reading from it on demand). What’s New in 0.
