Summary, scoring and Samples

Ed 1: Amazon Dolby Atmos – 2025

Presentation

This is the Amazon Dolby Atmos presented in Dolby Digital Plus (768 kbits/s).

Below the spatialization for all tracks. Click on the images to zoom in.

Waveform and Spectrum: DR14

The waveform of the Amazon Dolby Atmos – 2025 shows a high range confirmed with DR14.

The spectrogram of the Tidal Dolby Atmos track in 7.1.4 is limited to 20kHz (yellow arrow) with no signal above (white arrow). 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 green arrow shows the 120Hz filtering of the bass channel (LFE).

The graph below represents the spectrum of the Amazon Dolby Atmos – 2025.
The spectrum of Dolby Atmos version decoded in 7.1 shows that all channels are used. The LFE channel is used with a cutoff frequency of 80 Hz (green arrow). The white arrow indicates the high-frequency limit at 20 kHz due to Dolby Digital Plus encoding. The yellow arrow indicates the high-frequency limit at 24 kHz due to encoding at the 48 kHz sampling frequency used.

Synthesis and listening

The music was designed, recorded, and mixed to deliver a spatial sound experience. It is on a 7.1.4 configuration or higher that it reveals its full potential.However, this version, encoded in the lossy Dolby Digital Plus format, remains less precise and less detailed than the Dolby Atmos TrueHD version.

Rating:

• Dynamic: ●●●●o (4.5)
• Bandwidth: ●●●●o (4)
• Spatialization: ●●●●●●●ooo (7.5)
• Restitution: ●●●●o (4.5)

Sample : Tapestry 7.1 Dolby Atmos (Downmixed in 7.1) :

The sample is in 7.1 wav format, if you can not play the sample in your navigator, you can save it, right button menu and Save Audio As and play it with an external player.

Ed 2: Auro3D – 2025

Presentation

This is the immersiveaudioalbum.com edition, presented in mkv files including a Auro3D track, and the Stereo, Binaural and Dolby Atmos TrueHD Tracks. Also available in mp4 encoded in Dolby Digital Plus.

Below the spatialization for all tracks. Click on the images to zoom in.

Waveform and Spectrum: DR14

The waveform of the Auro3D – 2025 shows a high range confirmed with DR14.

The spectrogram shows the 80Hz filtering of the bass channel (LFE). For other channels, the signal rises to 48 kHz with no signal above this frequency due to the 96 kHz sampling frequency.

The graph below represents the spectrum of the Auro3D – 2025.
The 7.1 Auro3D is based on a sampling frequency of 96 kHz, limiting the bandwidth to 48 kHz. The LFE channel is filtered down to 80 Hz .

Synthesis and listening

Tested only in 7.1, this version delivers all the finesse and the fidelity of the original version recorded at 96 kHz. It is a pity that this sampling rate is not available in Dolby Digital Atmos TrueHD.

Rating:

• Dynamic: ●●●●o (4.5)
• Bandwidth: ●●●●● (5)
• Spatialization: ●●●●o (4.4)
• Restitution: ●●●●o (4.5)

Sample : Tapestry 7.1 24 bits 96 kHz:

The sample is in 7.1 wav format, if you can not play the sample in your navigator, you can save it, right button menu and Save Audio As and play it with an external player.

Ed 3: Binaural – 2025

Presentation

This is the immersiveaudioalbum.com edition, presented in mkv files including a binaural track, and the Stereo, Auro3D and Dolby Atmos TrueHD Tracks. Also available in mp4 encoded in Dolby Digital Plus.

Waveform and Spectrum: DR13

The waveform of the Binaural – 2025 shows a high range confirmed with DR13.

The spectrogram shows that the signal rises to 27 kHz with no signal above this frequency due to the 96 kHz sampling frequency.

The graph below compares the spectrum of the Stereo – 2025 (white curve) with the spectrum of the Binaural – 2025 (blue curve). Numerous differences can be observed between the curves of these two spectra (green and yellow zones), due to the different methods used to obtain the two tracks. The binaural version is a specific conversion derived from the Dolby Atmos version. The yellow arrow indicates that the binaural version extends less high in frequency, up to 27 kHz, compared to the stereo version, although this still remains well above 20 kHz.

Synthesis and listening

Presented in high-resolution format at 24 bit / 96 kHz, this binaural version is the best option for headphone listening, offering greater immersion than the stereo version, which is limited in dynamic range.

Rating:

• Dynamic: ●●●●o (4)
• Bandwidth: ●●●●● (5)
• Restitution: ●●●●o (4)

Sample : Tapestry 24 bits 96 kHz:

Ed 4: Dolby Atmos TrueHD – 2025

Presentation

This is the immersiveaudioalbum.com edition, presented in MKV files including a Dolby Atmos TrueHD track, as well as binaural, Auro-3D, and stereo tracks. It is also available in MP4, encoded in Dolby Digital Plus.

Below the spatialization for all tracks. Click on the images to zoom in.

Waveform and Spectrum: DR14

The waveform of the Dolby Atmos TrueHD – 2025 shows a high range confirmed with DR14.

The spectrogram shows that the green arrow shows the 80Hz filtering of the bass channel (LFE). The signal rises to 24 kHz with no signal above this frequency due to the 48 kHz sampling frequency.

The graph below represents the spectrum of the Dolby Atmos TrueHD – 2025.
The Dolby Atmos remix downmixed to 7.1 is based on a sampling frequency of 48 kHz, limiting the bandwidth to 24 kHz . The LFE channel is filtered down to 80 Hz.

Synthesis and listening

The music was designed, recorded, and mixed to deliver a spatial sound experience. It is on a 7.1.4 configuration or higher that it reveals its full potential. The listener is completely immersed in the heart of the music, thanks to the spatial distribution of the instruments, which makes each track fully immersive. It is a true demonstration of immersive sound.

Rating:

• Dynamic: ●●●●o (4.5)
• Bandwidth: ●●●●o (4)
• Spatialization: ●●●●●●●●oo (7.7)
• Restitution: ●●●●● (5)

Sample : Tapestry 7.1 Dolby Atmos (Downmixed in 7.1) :

The sample is in 7.1 wav format, if you can not play the sample in your navigator, you can save it, right button menu and Save Audio As and play it with an external player.

Ed 5: Stereo – 2025

Presentation

This is the immersiveaudioalbum.com edition, presented in MKV files including a stereo track, as well as binaural, Auro-3D, and Dolby Atmos TrueHD tracks. It is also available in MP4, encoded in Dolby Digital Plus.

Waveform and Spectrum: DR9

The waveform of the Stereo – 2025 version shows a low dynamic range confirmed with DR9.

The spectrogram shows that the signal rises to 48 kHz with no signal above this frequency due to the 96 kHz sampling frequency.

The graph below represents the spectrum of the Stereo – 2025.
The spectrum shows that the signal rises to 48 kHz with no signal above this frequency due to the 96 kHz sampling frequency.

Synthesis and listening

Unfortunately, this stereo version is dynamically compressed; for headphone listening, it is preferable to choose the binaural version.

Rating:

• Dynamic: ●●ooo (2.5)
• Bandwidth: ●●●●● (5)
• Restitution: ●●●oo (3.5)

Sample : Tapestry 24 bits 96 kHz:

This album is a true reference for immersive music, particularly with the Dolby Atmos TrueHD version, which delivers greater finesse in the sound reproduction and more precise spatialization, perfectly utilized, making it one of the best immersive albums available.

Dynamic Range measurements are shown below.

Dynamic Range comparaisons

Dynamic represents the ability to reproduce a wide range of sounds from the softest to the loudest. The target is to compare the dynamics of the music and not of the media (CD, digital files or vinyl).

For our 5 editions reviewed have obtained the following Dynamic Range (DR) :

	Amazon Dolby Atmos – 2025	Auro3D – 2025	Binaural – 2025	Dolby Atmos TrueHD – 2025	Stereo – 2025
Global	DR14	DR14	DR13	DR14	DR9

Max	DR19	DR17	DR15	DR19	DR9
Flow	DR13	DR13	DR12	DR13	DR08
Beyond	DR13	DR13	DR12	DR13	DR08
Repose	DR15	DR16	DR14	DR15	DR09
Tapestry	DR14	DR13	DR12	DR14	DR08
