CASE STUDIES
CASE STUDIES
"A/B Comparison: Logic over Volume" Note: Both tracks have been loudness-matched for a fair comparison. Pay attention to the transient clarity and the 'space' between instruments that was lost in the over-compressed original.
RESTORATION CASE #01
Nirvana — Spank Thru (1985 Demo) (sample)
TASK Full Stem Reconstruction. Deep neural isolation and detailed drum stem separation. Performed a full re-mix of the entire track from scratch to achieve a modern professional balance.
RESULT 40% dynamic range increase. Crisp articulation of every drum hit while preserving the raw archival energy. Fully optimized for vinyl reissue.

THE ENGINEER Neural Precision Meets Analog Soul.
Serhii Makarenko | Audio Engineering & Analog Research
The Story Behind CJ MARS Audio From Electronic Production to Analog Precision.
CJ MARS Audio is an independent software research project by Serhii Makarenko, a musician, arranger, and producer whose life has been defined by the pulse of electronic music. For years, Serhii worked deep within the digital realm, crafting tracks and exploring the boundaries of modern sound. However, a new curiosity eventually took hold: the challenge of the analog transition.
The "Loudness War" vs. The Physical Groove In an era of aggressive mixing and extreme digital mastering, Serhii became fascinated by a specific problem: How do modern, "crushed" tracks actually behave when transferred to physical media? He began researching restoration and mastering physics for analog formats, driven by the need to see if a hyper-compressed modern mix could survive the physical limitations of a vinyl groove or a magnetic tape.
Creating the "Testing Stand" To answer these questions, Serhii didn't just want to guess—he wanted to measure. This led to the development of a professional-grade "testing stand" in software form.
What started as a personal research tool for high-accuracy physical simulations (RIAA/IEC standards) evolved into CJ MARS PMST. It is a bridge between the digital producer's desk and the mastering lathe, designed to visualize how sound truly lives on physical media.
A New Chapter in Austria Now based in Lower Austria, Serhii continues to develop these proprietary sensing engines as part of an ongoing R&D initiative. His background as a producer gives him a unique advantage: he understands the creative energy of a track, while his research provides the scientific rigor needed to preserve it for generations.
The Philosophy "I created PMST because I wanted a virtual microscope for my own masters. I wanted to see the wear, the saturation, and the physical response before the needle even touched the record. Today, I'm sharing this research tool with the global audio community to gather professional feedback and further refine the technology."
Connect with the Project By using PMST, you are supporting independent research born from a genuine love for music and a respect for analog history.

Technical Expertise & Collaborative Research
Technical Expertise & Collaborative Research
I apply the proprietary PMST sensing technology to analyze and restore complex audio material as part of my ongoing research into analog physics. While the project is in its R&D phase, I am open to collaborative case studies and professional inquiries from engineers who require deep technical analysis of their masters.
Technical Restoration Focus I specialize in the non-linear reconstruction of audio damaged by digital clipping and aggressive limiting. My methodology effectively restores lost dynamic range and mitigates "de-clipping" artifacts.
Note on limitations: My research focus is on physical modeling accuracy. Please note that material with severe physical distortion, audible overdrive, or "burnt" signals (harsh fuzz) may have limited restoration potential due to the extent of the source data loss.
Submission Standards for Research Analysis
If you have audio material that requires high-accuracy restoration for a research case study, please follow these technical guidelines:
Format: WAV / AIFF (24-bit or 32-bit float).
Sample Rate: 44.1 kHz up to 192 kHz.
Headroom: -3dB to -6dB peaks.
Mix State: Dry mix (No limiters/clippers on the master bus).
