Waveform
The waveform represents the Side A of the album.
The graph clearly shows the differences in levels and thus in dynamics for this track. You can clearly see the differences in volume and musical instruments impact.

Spectrum
The Spectrum allows to check the tonal balance of the music (balance between treble, medium and bass sounds) and to detect process that may have been carried out during the recording, the mixing, mastering or manufacturing phases. It is also possible to detect frequency interference issues.
The curve represents the average frequency distribution over the Side A of the album. Interesting characteristics on this curve are:
1. The spectrum between the two versions is similar, except above 3 kHz, where the vinyl remastered in 2014 has more treble than the vinyl of 1991 (in the green zone).
2. It is a collapse in the signal level after 22 kHz (Yellow), normal for a master in 44.1 kHz.

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 zones represent the collapse at 22 kHz (in Yellow in the previous graph).
- The whites zones focus on an horizontal line which is a peak in frequency, see the zoom of the spectrum in the white circle.

Waveform
The waveform represents the Tracks equivalent of the vinyl’s side A.
The graph clearly shows the differences in levels and thus in dynamics for this track. You can clearly see the differences in volume and musical instruments impact.
Like the vinyl 1991, the waveform is dynamic.

Surface Noise
This new curve that represents the surface noise of vinyl.
In white the Ed1 Vinyl 1991, in blue the Ed2 Vinyl 2014.
Between 100 and 300 Hz, there is almost 10 dB of deviation.
Above 3 khz, the Ed1 (Vinyl 1991) noise decreases, while the Ed2 noise remains constant up to 20 kHz.
This is certainly due to the master used. The Ed2 (Vinyl 2014) master seems to have a limited definition (less than 24 bits) or adding noise.
