Audio Refiner

Your favorite performance, a precious field recording, or a home-studio demo. "The performance is perfect, but the sound quality is lacking." To all audiophiles and creators who have felt this—AudioRefiner is built for you.

[ Have you ever experienced these audio frustrations? ]

● "The bass disappears on my phone speakers."
Even the best bass track can't be heard on small transducers. AudioRefiner uses psychoacoustic synthesis to make the low-end "audible" on any device.

● "Old CD tracks sound quiet and thin compared to modern music."
Legacy recordings often lack the "density" of modern masters. Our look-ahead maximizer boosts LUFS levels without sacrificing signal integrity.

● "The voice sounds muffled or 'under a blanket'."
Traditional EQ often makes things harsh. Our harmonic exciter restores the lost "Air" and high-end detail, making voices sound clear and immediate.

● "Instruments are clumping together in the center."
When recordings lack separation, they sound small. Our spectral unmasking technology identifies overlapping frequencies to give every instrument its own space.

[ The Science of Sound: Technical DSP Specifications ]

AudioRefiner is a high-precision Digital Signal Processing (DSP) utility designed to analyze and optimize audio signals with objective accuracy.

● Harmonic Excitation & Spectral Shaping
Utilizes high-pass filtering and polynomial soft-clipping algorithms to synthesize high-frequency harmonics. This restores clarity without the phase distortion associated with traditional EQ.

● Psychoacoustic Bass Enhancement
Implements "Missing Fundamental" theory to generate sub-harmonic series. This allows low-frequency content to be perceived on transducers with limited physical response without exceeding mechanical excursion limits.

● Look-ahead Peak Limiting (Maximizer)
A 5ms look-ahead limiter with adjustable input gain and ceiling parameters. Features an intelligent release curve to increase signal density while maintaining peak normalization and preventing digital clipping.

● Instrument Separation & Spectral Unmasking
Employs WOLA synthesis and spectral contrast enhancement. By exaggerating panning differentials above 600Hz, AudioRefiner reduces masking and increases the definition of individual instruments.

● Precision Manual Control (Advanced Users)
Every DSP module is fully adjustable via precision sliders. Gain access to:
- Drive and Mix levels for Harmonic Exciters
- Input Gain and Ceiling for Limiters
- Pitch, Tempo, and Formant shift ratios
- Spectral separation and contrast intensity
