 Waveform

The waveform is that of track 3 “Take Five”, a representative track of the album.

It shows that this edition respects the dynamics of the track without saturation or clipping. You can clearly see the differences in volume and musical instruments impact between the right and left channels as well as the changes over time.

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 shows the frequency distribution over the Track “Take Five”. Interesting characteristics on this curve are:

1. A progressive decrease in frequency above 15kHz (Yellow), without noise above 20 kHz.
2. Two very small frequency peak above 30 kHz (Red) certainly due to a parasitic electronic equipment near the recording equipment or a defect in the production process. There is no reason to worry because the interference level is very very low (- 110dB).

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 arrows represent the progressive decrease in frequency above 15kHz, With some noise above 20 kHz.

Waveform

The waveform is that of track 3 “Take Five”, a representative track of the album.

As Ed 1, the graph clearly shows that there is neither exessive compression nor saturation but a lower recording level. The phase of the signal is inverted compared to the other editions. The green area should be on top and not below the waveform. This should have no impact on the quality of the recording.

Spectrum

Next picture shows the frequency distribution over the Track “Take Five”. Interesting characteristics on this curve are:

1. The level (Green) above 10 kHz is almost 5 to 10 dB louder than Ed1 Vinyl Sony.
2. There is small frequency peak above 20 kHz (Red) probably due to a parasite generated by an analog electronic device. It’s a full analogic transfert. Comparing to the Ed1 vinyl Sony, it is digitally remastered, which makes it easier to correct defects in the original tape.

Spectrogram

• The yellow arrows show the progressive decrease in frequency above 15kHz.
• The red arrows show the noise above 20 kHz (in Red in the previous graph).
