Andre Mehmari – Invisible Cities – Part One (Steaming Dolby Atmos)

Presentation

This is the Tidal Dolby Atmos presented in Dolby Digital Plus or AC-4 (link).

We find here the same spirit as in the album Invisible Cities: Part Two, with a fully immersive musical experience. The 5.0.4 recording provides a very natural rendering, along with a strong sense of space and volume typically found in recordings made using immersive microphone techniques.
To achieve a perfectly coherent spatial soundstage, it is preferable to listen in a 5.1.4 setup to fully benefit from the album s quality, as in 7.1.4 mode, distributing the music across the four surround speakers increases the sense of room presence.

For the best sound quality, lossless formats are available for download on NativeDSD in Stereo (DSD64, DS128, DSD256, DSD512, DXD, WAV 176.4kHz), 5.1 format (DSD64, DS128,DSD256, DXD, FLAC 96 kHz) and 5.1.4 (DXD and Dolby Atmos TrueHD in MKV) formats.

Waveform ,Spectrum and Dynamique: DR14 (Min: DR13 , Max: DR15)

The waveform of the Tidal Dolby Atmos – 2026 shows a high range confirmed with DR14.

The spectrogram of the Tidal Dolby Atmos track in 7.1.4 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 LFE channel is not used.

The graph below represents the spectrum of the Tidal Dolby Atmos – 2026.
The spectrum of Dolby Atmos version decoded in 7.1 shows that all channels are used. The LFE channel is not used. The white arrow indicates the high-frequency limit at 20 kHz due to Dolby Digital Plus encoding. But the max high-frequency limit is 24 kHz due to encoding at the 48 kHz sampling frequency used.
