Audio Refiner

Your favorite performance, a 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.

[ July 2026 Update ]

・Real-Time Audio Processing:

Hear every supported effect instantly as your audio plays. Fine-tune your sound with immediate feedback—no repeated exporting required.

・Smart Keyword-Based Effect Matching:

No complex DSP knowledge required! Type in your audio problem (e.g., "muffled", "lacks bass", "clear", "boomy") and AudioRefiner instantly applies the ideal DSP combination.

[ Common Audio Problems AudioRefiner Solves ]

● "The voice sounds muffled or lacks clarity."

Restores lost high-end detail and harmonics, making voices sound crisp, warm, and clear without harsh EQ.

● "The bass disappears on my phone speakers."

Uses psychoacoustic synthesis to make low-end frequencies audible on small transducers without distortion.

● "Old CD tracks sound quiet, thin, or weak."

Our look-ahead maximizer boosts signal energy and LUFS levels while preserving audio integrity.

● "Instruments are clumping together in the center."

Spectral enhancement technology expands the stereo field to give every instrument its own space.

[ Technical DSP Specifications ]

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

● Smart Keyword Preset Recommendation

An instant, offline matching engine that maps your description directly to specialized DSP parameter chains—eliminating trial-and-error without network latency.

● Harmonic Excitation & Saturation

Utilizes high-pass filtering and polynomial soft-clipping algorithms to synthesize high-frequency harmonics, adding warmth and clarity without phase distortion.

● Psychoacoustic Bass Enhancement

Implements "Missing Fundamental" theory to generate sub-harmonic series, allowing low frequencies to be perceived on limited-range transducers.

● Look-Ahead Peak Limiting (Maximizer)

A 5ms look-ahead limiter with adjustable input gain and ceiling parameters, featuring an intelligent release curve to boost signal density while preventing clipping.

● Instrument Separation & Spectral Unmasking

Employs WOLA synthesis and spectral contrast enhancement above 600Hz, reducing masking and refining instrument definition.

● Complete Manual Control

Describe what you hear in plain words, or take full manual control using precision sliders:

- Drive and Mix levels for Harmonic Exciters & Saturation

- Input Gain and Ceiling for Limiters

- Pitch, Tempo, and Formant shift ratios

- Spectral separation and contrast intensity

- Cutoff frequencies for Low-Cut/High-Pass filters
