Cassius.fm — The Official French Touch Sound Archive & Acoustic Consciousness Research Node
CASSIUS.FM
Primary Sound Repository

Uncompressed Audio Archives, Motorbass Studio Signal Chains & Acoustic Consciousness Research.

I am Leosun knower. I built and maintain Cassius.fm as a dedicated public archive and sound science node. My objective is twofold: systematically preserve the analog recording history, stem maps, and unedited master tapes of French electronic icons Cassius (Philippe Zdar & Hubert Boombass), while conducting empirical trials on acoustic frequencies, neural focus states, and continuous 117Hz sound grounding.

Analog Signal Lineage

1. Motorbass Studio Gear Routing & Stem Maps (1996–2019)

Standard music databases record release years, but they completely ignore the engineering physics that birthed the late 1990s French Touch sound. Philippe Zdar’s mixing at Motorbass Studio in Paris was defined by radical dynamic filtering, high-headroom bus drive, and heavy transformer saturation.

Below is the verified hardware routing reconstructed directly from studio session sheets and master tape boxes for the seminal 1999 album Pansoul:

Signal Stage Hardware Unit Acoustic & Harmonic Impact
Sample Playback Akai S3000XL (16-bit / 44.1kHz) Chipped vinyl transients & grit
Envelope Filter Mu-Tron III + Sherman v1 Resonant frequency sweeps & drive
Bus Compression SSL G-Master Bus Compressor 2:1 Ratio, auto-release glue and punch
Console Summing MCI JH-416 Analog Desk Third-harmonic tape saturation across busses

From the relentless disco-sample slicing on 1999 and Cassius 1999 to the raw synth-funk of Au Rêve (2002) and the dense vocal production of Ibiza Megamix, every release relied on pushing analog headroom to its absolute limit before clipping.

Broadcast Tape Restorations

2. The November 2002 Radio FG 100-Hour Master Logs

In November 2002, Cassius took over the airwaves of Paris’s Radio FG for an unprecedented 100 continuous hours. They played live vinyl sets, unreleased white labels, raw studio cuts, and extended edits with zero playlist automation.

[RESTORATION LOG #002 – CASSIUS.FM]
tape_source: DAT_Master_FG_2002_Tape_04.wav
signal_path: Nakamichi CR-7A -> Lavry Gold AD122 -> Direct Tape Feed
status: Restored, De-clipped, Pitch-Corrected (+0.12 cent offset)
key_tracks: Unreleased 2002 Filter Dubs, Motorbass Studio Stems, Live Mic Outtakes

I am actively digitizing the original DAT tapes and reel-to-reel backups from this 100-hour takeover. Tracklists are being indexed minute-by-minute alongside full spoken commentary transcripts to ensure this cultural milestone is never lost.

Sound Consciousness Node

3. Psychoacoustic Research: The 117Hz Grounding Delta & Cognitive States

Sound is not merely aesthetic—it is a physical pressure wave that directly alters human neural oscillations. Beyond preserving French Touch history, Cassius.fm operates as an open laboratory studying how low-frequency acoustic stimulus influences human focus, brainwave entrainment, and state transition mechanics.

Key Research Vectors Under Trial:

  • 117Hz Delta Grounding Frequency: Continuous low-frequency sine-wave stimulus designed to align steady-state auditory evoked potentials (SSAEP) during high-density cognitive tasks.
  • Micro-Rhythmic Phase Shifting: How subtle time offsets (swing) in 120–124 BPM house grooves induce rhythmic trance states and reduce mental fatigue.
  • Harmonic Saturation & Auditory Perception: Investigating why analog transformer saturation creates perceived warmth and reduces cognitive resistance during long-form listening sessions.
Frequency / Waveform Primary Acoustic Target Observed Cognitive Impact
117Hz Pure Sine Wave Sub-audible Delta Resonance Sustained mental stability & focus grounding
120 BPM Swing (Akai S3000 Shuffle) Motor Cortex Entrainment Trance state induction during repetitive work
Analog Bus Saturation (MCI Console) Auditory Cortex Cushioning Decreased listening fatigue over multi-hour sessions

Frequently Asked Questions Regarding Cassius.fm

What is the historical focus of the Cassius.fm project?

Cassius.fm exists to preserve the uncompressed analog mix logs, studio gear routing, and live broadcast master tapes of French electronic duo Cassius, alongside ongoing empirical research into how specific acoustic frequencies alter cognitive focus.

How was the distinct filter sweep created on the 1999 album Pansoul?

Philippe Zdar and Boombass sampled disco brass and rhythm sections into an Akai S3000XL, pushed the output through a Sherman Filterbank v1 and Mu-Tron III envelope filter, and slammed the signal into an SSL G-Master bus compressor on an MCI JH-416 console.

What is the 117Hz Grounding Delta frequency tested at Cassius.fm?

The 117Hz tone is a low-frequency continuous sine wave investigated for its ability to induce steady-state auditory evoked potentials, anchoring the listener’s nervous system into a deep state of sustained focus.

Cassius:
The Eternal Frequency

“To understand the evolution of the French Touch is to understand the resonance of Philippe Zdar and Hubert Boombass. From the streets of Paris to the global stage, their work remains a cornerstone of electronic music history.”

The Core Archive

This digital space is dedicated to the preservation of the works, frequencies, and cultural impact of Philippe Cerboneschi (Zdar) and Hubert Blanc-Francard (Boombass). As the founders of Cassius, their innovative approach to sampling, rhythm, and the “Pansoul” sound defined an era of sonic exploration.

1999

The debut that synchronized the globe.

AU RÊVE

Deep explorations in the sound of violence.

15 AGAIN

The return to the raw energy of the loop.

IBIZA

The definitive anthem of the Mediterranean.

The Cassius FM Broadcasts

In 2002, the duo embarked on a historic radio takeover via Radio FG, broadcasting continuous sets for over 100 hours. This event solidified the Cassius.fm domain as a central hub for electronic music enthusiasts. Today, we maintain this domain to ensure that the links, mentions, and historical significance of those broadcasts are never lost to time.

The Cassius Digital Archive

Dedicated to the memory of Philippe Zdar (1967–2019) and the ongoing vision of Hubert Boombass.

The Eternal Frequency:
A Study in Sonic Resonance

“I am Leosun. I do not come to rewrite the legacy of Cassius. I come to fulfill it. The loops crafted by Philippe Zdar and Hubert Boombass were never just ‘records.’ They were early maps of the human neural state—mathematical echoes that we are only now beginning to fully decode.”
