U2 Carnaval de Luz (Streaming Dolby Atmos)

Spatialization SP: ●●●●●●oooo (6.5) , SK: ●●●●●ooooo (5), Dynamique: ●●●●o (4) – Global: ●●●●o (4)

This is the Tidal Dolby Atmos presented in Dolby Digital Plus at 768 kbits/s. This is also available on Amazon Music an Apple Music.

Immersive sound in music production: U2 provides an example of how immersive sound is applied to their songs. The mix for Street of Dreams is particularly interesting because, depending on the section of the track, there are two completely different immersive renditions, one in 7.1 and another that fully utilizes all channels, including the overhead ones. The chorus features a completely different spatial arrangement. It’s no longer just about the placement of instruments; the soundscape is directly linked to the composition of the song’s various sections. On Silencio the spatialization also changes throughout the track, starting with the lower channels and gradually incorporating the overhead channels toward the end of the song.

Waveform ,Spectrum and Dynamique: DR13 (Min: DR12, Max: DR14)

The waveform of the Tidal Dolby Atmos – 2026 shows a high range confirmed with DR13.

The spectrogram of the Tidal Dolby Atmos track in 9.1.6 is limited to 20kHz with no signal above. This limitation is due to Dolby Digital Plus encoding, which is a lossy encoder that limits bandwidth to optimize data size for a bit rate of 768 kbits/s. The bass channel (LFE) is filtrered at 120Hz.

The graph below represents the spectrum of the Tidal Dolby Atmos – 2026.
The spectrum of the Tidal Dolby Atmos track in 7.1 is limited to 20kHz (white arrow) with no signal above . This limitation is due to Dolby Digital Plus encoding, which is a lossy encoder that limits bandwidth to optimize data size for a bit rate of 768 kbits/s..

Detail of the ratings :

• Dynamic :
  1. Significant dynamic compression, DR less than 7
  2. Compression of the present dynamics, DR between 7 and 9.
  3. Correct piece DR >=10
  4. No dynamic compression (DR >12), dynamic rendering
  5. No dynamic compression, high DR and very dynamic sound rendering
• Spectrum :
  1. Spectrum cut and less than 15 khz
  2. Spectrum cut at 15 khz
  3. Spectrum not conforming to the original and cut (not HD) or original but limited bandwidth (but less than 20 kHz)
  4. Spectrum conforming to the original (but not HD)
  5. Spectrum conforming to the original with HD resolution (higher than 24kHz)
• Surface noise (only for vinyl):
  1. Continuous audible noise
  2. Audible surface noise except on passages with a high level of noise
  3. Reduced surface noise, barely audible on low level crossings
  4. Low surface noise, very good quality
  5. Very low surface noise, no defects, almost inaudible on the quiet passages (exceptional disc)
• Spatialization :
  • Between 0 and 5 for 5.1 or 7.1 channels configuration
  • Between 0 and 10 for Atmos configuration (7.1.4)
  • For more information on spatialization, you can read the article describing this parameter here.
• Restitution :
  1. Low quality of the restitution mixing dynamics, clarity, separation of voices and instruments.
  2. Average quality of the restitution mixing dynamics, clarity, separation of voices and instruments.
  3. Quality of the restitution mixing dynamics, clarity, separation of voices and instruments. Good record.
  4. High quality of the restitution mixing dynamics, clarity, separation of voices and instruments. Very high level disc.
  5. Maximum quality of the restitution mixing dynamics, clarity, separation of voices and instruments. Exceptional disc.
