Waveform
This edition is dynamic, we can see many attacks of the guitar that give this dynamic rendering. As opposed to the Ed4 CD and Ed5 CD Deluxe version which is a little compressed.
Spectrum
The curve represents the average frequency distribution over the sample “Before You Accuse Me”. The Yellowarea shows the limit à 20 kHz due of the digital master. The green area shows a slightly lower level above 10 kHz for the streaming version compared to the Ed4 CD.
Spectrogram
Spectrogram is another representation of frequency versus time of a track. For each channel (right and left), horizontal axis represents time, and the vertical axis represents frequency. The amplitude is represented by the intensity (brightness) of the color of each point in the image.
The yellow arrow represents the normal collapse arround 20 kHz (sampling frequency of the master at 44.1 kHz). Above 20 kHz , there is no signal (black area).
