| Reference | Download with code included in CD or Vinyl |
| Format (speed) | Digital File 5.1 |
| Type | 5.1 file 24 bits 48 kHz |
| Master | Digital |
| Mastering/Pressing | Europe |
| Original recording | Digital |
| State | Europe |
| Year original | 2021 |
| Year production | 2021 |
Waveform
The waveform represents all the Tracks of the album.
The curve clearly shows the 6 track L, C, R, Sl, Sr,LFE. The LFE is not use, the format is more exactly 5.0.
The music was created for this format, there are many differences between the tracks, which will give an important spatial distribution of the music.
Spectrum
The curves represent the frequency distribution of the L, C, R, Sl ,Sr and LFE channels.
The interesting features on this curve is the high frequency cuts to 23kHz which is almost the maximum frequency of the digital master for 48 KHz files.
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 green arrow represent the normal collapse at 23 kHz .The black part shows no signal above 23kHz.
Ed5 : Streaming Ultra HD – 2021
Presentation
This is the streaming release in Ultra HD (24 bits 48 kHz) from Amazon Music HD.
| Label | Polydor |
| Reference | Amazon Music HD |
| Format (speed) | 24 bits 48 kHz |
| Type | 24 bits 48 kHz |
| Master | Digital |
| Mastering/Pressing | Europe |
| Original recording | Digital |
| State | Europe |
| Year original | 2021 |
| Year production | 2021 |
Waveform
The waveform represents 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.
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 24kHz which is the maximum frequency of the Streaming at 48 kHz.
The spectres of CD and the Streaming overlapping on the curve, which shows a limit at 22 kHz, we can question if the original master is not made in 44.1 kHz and not 48 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.
It can be seen the collapse at 22 kHz . The black part shows no signal above 22kHz. Normal forthis digital Master.
