WebDec 9, 2012 · Scalogram can provide useful info. For example it is great for visualizing voice versus noise feature. Voice is more rich and irregular in structure, noise is more monotonic and repetitive. Horizontal axis is time. Vertical axis is octaves. Higher frequencies are resolved at lower octaves and lower frequencies at higher octaves. WebThe scalogram is the absolute value of the CWT plotted as a function of time and frequency. The plot uses a logarithmic frequency axis because frequencies in the CWT …
