Random Access Memories is the fourth and final album by Daft Punk, released in May 2013. This album received the Grammy Award for Best Album of the Year in 2014. It contains the famous track Get Lucky.

May 12, 2023: French electronic music group Daft Punk is celebrating 10 years since the release of their legendary album “Random Access Memories,” which won multiple Grammy Awards in 2014. To mark this special occasion, the band’s two members, Thomas Bangalter and Guy-Manuel de Homem-Christo, are releasing an expanded anniversary edition of their latest album, entitled “Random Access Memories 10th Anniversary Edition.”

This reissue includes several bonuses for the fans. In addition to the 13 original tracks from the album, this anniversary edition contains 35 minutes of unreleased music spread over 9 tracks, with new Daft Punk tracks that have never been heard before.

The band also worked with artists and designers Warren Fu and Nick Knight to create a new series of images in the form of posters included in the anniversary edition of the album.

The review is updated with the Tidal Sony 360 Reality Audion and Apple Music Dolby Atmos versions.

Part 2 : Waveform and dynamic comparaisons

Waveform

The waveform represents all the 13 tracks of the album.

This edition Ed1 vinyl is dynamic, we can see many attacks of the music that gives this dynamic rendering. The graphic below shows the 13 tracks of the vinyl.

This edition 10th anniversary Ed7 vinyl is similar to the Ed1 vinyl with dynamic, we can see many attacks of the music that gives this dynamic rendering. The two graphics below show the 13 tracks of the first two LP and the new tracks of the 3rd LP.

The seven digital versions ( Original and 10th anniversary) are similar, with the presence of signal compression that caps the peak level, as shown by the yellow circles. The compression is done “cleanly”, with no clipping effect.

In the case of the CD, with a maximum level at 0dB, we find a true peak level at 0.74 dB, that is to say that we go above 0 dB. This happens only on some very narrow peaks, and depending on the capacity of the DAC to manage these peaks, it will produce a little distortion. The other digital supports are a little below 0dB, and will have a true peak level lower than 0.74 dB.

The waveform below represents the Tidal 360RA (Ed10) version decoded in 5.1. We can see that this version is more dynamic than the digital stereo versions. The center channel is not used much. For the LFE channel (bass), it is not used.

The waveform below represents the Apple Dolby Atmos (Ed11) version decoded in 5.1. We can see that this version is more dynamic than the digital stereo versions. The center and bass channel (LFE) are little, or even very little used.

Dynamic

We start this test by measuring the dynamic. Dynamic represents the ability to reproduce a wide range of sounds from the softest to the loudest. 

For our 11 editions we have obtained the following Dynamic Range (DR):

	Ed1: Vinyl	Ed2: Qobuz DL	Ed3: Qobuz Streaming	Ed4: Tidal	Ed5: Amazon	Ed6: CD	Ed7 : Vinyl  (10th Anniversary Edition)	Ed8: CD (10th Anniversary Edition)	Ed9: Qobuz  (10th Anniversary Edition)	Ed10 : Tidal Sony 360 RA	Ed11 : Apple Music Dolby

The Dynamic Range for the 5 stereo digital versions is similar with a DR8 on average. This is in line with the waveforms. The Dolby Atmos and Sony 360RA versions are more dynamic with a DR13 (measured in 5.1) for these spatial audio versions. The vinyl benefits from a greater dynamic DR13, which is due to a less limited master or to a transformation of the analog support (see here).

As a reminder, the scale goes from 0 to more 20, but the dynamics are considered good from 12, quite good between 10 and 11, and deteriorate below 10.

Part 3 : spectrum comparisons

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 “Get Lucky”.

The interesting features on this curve Ed1 Vinyl (white) vs Ed2 Qobuz (blue) are the following:

1. The two curves are superposed between 60 Hz and 15 kHz.
2. The yellow area shows an attenuation of more than 5 dB of vinyl above 15 kHz compared to the digital version). The difference in level in the high frequencies will be audible.
3. The yellow arrow shows that the noise floor of vinyl is higher than that of digital above 30 kHz, but the level remains very low.
4. The green area shows an attenuation of the bass on the vinyl compared to the digital version below 50 Hz, with more than 3 dB at 30 Hz.

For the Ed2, Ed3 and Ed4, all three in 24 bits 88.2 kHz sample rate, we find a superposition of the frequency response.

The Ed5 and Ed2 are superimposed up to 24 kHz (yellow arrow), limit frequency of the Amazon version (white) due to the sampling frequency of 48 kHz compared to 88.2 kHz for other digital versions.

The Ed6 and Ed3 are superimposed up to 22 kHz (white arrow), limit frequency of the CD (white) due to the sampling frequency of 44.1kHz compared to 88.2 kHz for the Qobuz digital version.

For the Ed3 Qobuz Streaming and the Ed9 : Qobuz Hi-Res 10th anniversary, in 24 bits 88.2 kHz sample rate, we find a perfect superposition of the frequency response.

For the Ed6 CD and the Ed8 : CD Hi-Res 10th anniversary, in 16 bits 44.1 kHz sample rate, we find a perfect superposition of the frequency response.

For the Ed1 vinyl and the Ed7 : Vinyl 10th anniversary Edition, we notice a difference in mastering and cutting of the vinyl records. The vinyl record of the 10th anniversary is raised a little higher in the high frequencies (up to 8 dB more at 18 kHz) (yellow zone) and a little more low frequencies (green zone) up to 1 to 2 dB around 30 Hz. This should be noticeable in the listening experience with more bass and more detailed highs.

The spectrum below represents the sample of the Ed10 360RA decoded in 5.1. We can see that the maximum frequency is below 20 kHz (yellow arrow), the limitation to 20 kHz is due to the encoding in MPEG-H format. The front channels have a higher level than the side and surround channels. On this sample, there is no signal in the bass channel (LFE). The spectrum in 360RA is very similar to the spectrum in Dolby Atmos.

The spectrum below represents the Ed11 Dolby Atmos sample decoded in 5.1. We can see that the maximum frequency is below 20 kHz (yellow arrow), the limitation to 20 kHz is due to the encoding in Dolby Digital Plus (E-AC3). The front channels have a higher level than the surround channels and the center channel. On this sample, there is no signal in the bass channel (LFE).

Part 4 : Spectrogram comparaisons

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 spectrograms of the Ed1 Vinyl and Ed7 Vinyl 10th anniversary Edition , show that the frequencies rise above 20 kHz (yellow arrow). The white arrow represents a part of the signal mixed with distortion due to the functioning of the vinyl record..

* The difference in color intensity is due to the new settings used for the new measurements allowing a better visibility of the spectrum.

The Ed2, Ed3, Ed4 and 10th anniversary edition Ed9 Qobuz Hi-Res have a high bandwidth above 20 kHz (indicated by the yellow arrow). This is a true 88.2 kHz mix.
The black arrows indicate small parasitic frequency peaks present on all the tracks of the album at a frequency of 30 kHz.

* The difference in color intensity is due to the new settings used for the new measurements allowing a better visibility of the spectrum.

As for the spectrum, the Ed5 has a limited bandwidth of 24 kHz (yellow arrow). The black area (white arrow) shows that there is no signal above 24 kHz.

As for the spectrum, the Ed6 CD has a limited bandwidth of 22 kHz (yellow arrow) due to the sampling frequency of the CD (44.1 kHz). The black area (white arrow) shows that there is no signal above 22 kHz.

The spectrogram below represents the ED10 Tidal 360RA decoded in 5.1. We find a maximum frequency below 20 kHz (yellow arrow) without any signal above (white arrow). There is no signal on the bass channel (green arrow).

The spectrogram below represents the ED11 Apple Dolby Atmos decoded in 5.1. We find a maximum frequency below 20 kHz (yellow arrow) without any signal above (white arrow). There is little signal on the bass channel (green arrow), with a very strong attenuation above 120 Hz.

* The difference in color intensity is due to the new settings used for the new measurements allowing a better visibility of the spectrum.

Part 5 : Spatialization

Spatialization allows you to define the sound distribution of the music on all the channels. The spatialization indicator and the description of the graph are described here.

The graphs below represent the spatialization of the Ed10 Tidal 360RA and Ed11 Apple Dolby Atmos versions. We find an exploitation of all the channels, with a more or less important exploitation according to the songs.

Below the spatialization for the 13 tracks of Apple Music Dolby Atmos version. Click on the images to zoom in.

Part 6 : Summary, scoring and Samples

Ed1 : Vinyl ref 60250742562- 2013

Very nice pressing of the vinyl. The vinyl version has a softer and more open feel than the digital versions. There is a little less extreme bass, a very dynamic listening despite the slight attenuation of the highs compared to the digital versions.

Ed10 : Tidal Sony 360 Reality Audio – 2023

The version in Sony 360 Reality Audio goes a little further in the rendering of the spatial sphere than with Dolby Atmos, the sound space seems more aerial and more precise. We find the same characteristics described for “Contact”, “Giorgio”, “Touch”, “Get Lucky” with Dolby Atmos (see the description below), but with a little more air, space.

Ed11 : Apple Music Dolby Atmos – 2023

The mixing in spatial sound is a real success for this album of electronic music which seems to have been imagined for this principle of restitution.

On “Contact”, the atmosphere of the space sound immerses us in the music, with the voice above our heads then the music surrounds us and the bass is there, present with a lot of energy and dynamics.
The sound effects are really around us.
The enlargement of the sound space exploits a positioning of voices, instruments, sound effects in the 3D space, while keeping a beautiful frontal energy.
On “Giorgio”, the word of the beginning is very clear while being plunged in an atmosphere then, we follow the movement of the music which rocks us in the room with a beautiful dynamics.
On “Touch” the music plays in the space as if it had been conceived for that.
On “Get Lucky”, we want to clap our hands to follow the rhythm of the music that surrounds us at 360 degrees literally.

Very nice version in Dolby Atmos.

  • Dynamic: ●●ooo (2/5)
  • Bandwidth: ●●●●● (5/5)
  • Spatialization: ●●●●●●●●oo (7.6)
  • Restitution: ●●●●o (4/5)

Between digital (CD, streaming and download) and vinyl, if you prefer a dynamic listening, drier bass and a more open warm sound, vinyl is for you, it is the most pleasant sound. If you prefer a heavier sound, more extreme bass, and more treble, it’s the digital version with its compression. It is a pity not to have this digital version with more dynamics.

Updated with 10th anniversay Editions : As for the previous versions, we find the same difference between the digital versions and the vinyl record. The balance of the vinyl record of this 10th anniversary edition is a little clearer and present in the bass, making this an excellent anniversary vinyl edition. But what characterizes especially this new edition, those are the additional tracks as “Infinity Repeating” and “The Writing of Fragments of Time”, and also the versions in spatial audio which will be tested soon.

Updated with Apple Music Dolby Digital and Tidal Sony 360RA releases: this is the real revelation of this 10th anniversary of Random Access Memory, the Dolby Atmos and Sony 360 Reality Audio versions bring a new vision and listening of this album. The spatial mix is perfectly adapted to this electronic music, it’s a great success, with a Sony 360RA version that offers a little more space in the sound rendering. If you have the opportunity, listen to this album at least in 7.1.4.
