Waveform

The waveform represent all the tracks of the album.

 This edition is very dynamic, we can see many attacks of the instruments that gives this dynamic rendering. As opposed to the Ed2 CD version which is compressed.

Waveform Ed1 Vinyl

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 sample track “Part 5”.

The interesting features on this curve are the following:

  1. The high frequency cuts at 22kHz (Red) which is the maximum frequency of the digital master.
  2. The treble level above 15kHz is lower (yellow) than on the Ed2 CD.
  3. The bass below 50 Hz, ion green, is louder (5 dB) on the Ed2 CD than Ed1 Vinyl.

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 shows the little collapse at 22 kHz due of the mastering at 44.1 or 48 kHz. Beyond 22kHz, we find the background noise and harmonics created by the vinyl playback.

Waveform

The waveform represent all the tracks of the album.

As opposed to the Ed1 Vinyl , the version Ed2 CD is compressed. In yellow, the areas showing that the maximum CD level has been reached. This will limit the dynamics, which explains the DR9.

Spectrum

 The curve represents the average frequency distribution of the sample track “Part 5” title. The interesting feature on this curve is the high frequency cuts to 22kHz which is the maximum frequency of the digital master for 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.

It can be seen the normal collapse at 22 kHz of the CD. The black part shows no signal above 22kHz.
