Waveform
The waveform represents all the Tracks of the album.
Like the Ed1 Vinyl, this edition is dynamic, we can see many attacks of the instruments that gives this dynamic rendering. As opposed to the Ed1 CD 2021 and Ed4 CD 2019 version which is a little compressed.
Spectrum
The curve represents the average frequency distribution over the sample “Comfortably Numb”. The curves of the Ed2 CD and the Ed3 Streaming are completely overlapping. We will find the same tonal balance.
The only little difference is that the Ed3 Streaming version drops faster at 22 kHz than the Ed2 CD, but at too low a level without any impact.
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 at 22 kHz (sampling frequency streaming at 44.1 kHz).The black part shows no signal above 22kHz.
