Coming Soon · Version 0.5

Your records,
rebornlive.

Kraken Vinyl Elixir strips decades of clicks, crackle, hiss, rumble and hum the instant your needle hits the groove — without stealing the warmth that makes vinyl worth playing.

A hi-fi restoration engine wrapped in a vintage-receiver interface. Predictive DSP that rebuilds the waveform instead of muting it. Runs on a Raspberry Pi you own — no cloud.

Hear it clean itself

Flip between the raw record and the Kraken-cleaned output. Same passage, same moment — one just breathes again.

Cleaned

1970 Waycross High School Symphonic Band

Why it's different

Eight arms. One clean signal.

A full restoration chain running in parallel, in real time — each stage tuned to protect the music.

🎯

Predictive de-click

Linear prediction (AR/LSAR) rebuilds the missing waveform under each pop from the music around it. You hear the note — not a hole.

De-crackle

A retuned predictor hunts the dense surface crackle the de-click stage leaves behind — without smearing the highs.

🌫️

Spectral de-noise

Learns the hiss from a silent groove, then gates it out with minimum-statistics spectral subtraction. Kills noise, keeps air.

〰️

Rumble & hum

Subsonic rumble high-pass plus a 50/60 Hz notch bank that removes mains hum and its harmonics dead.

🎧

Hear what's removed

The killer feature: solo the clicks, crackle, or hiss on their own. If you hear the song in there, it's wrong — and it won't.

🎚️

Tone EQ

Six-band graphic EQ with genre presets — Classical, Rock, Country, Jazz, Warm Vinyl — applied after cleanup.

📟

10 vintage meters

Analog VU, Russian magic-eye tubes (6E5, 6E1P, 6E2/EM87), 80s VFD, stereo spectrum, peak/dB — switch on the fly.

🔒

Yours. Offline.

Runs on your own Raspberry Pi 5. No cloud, no account, no phoning home. Auto-calibrates itself to each record.

📊

Proof, not promises

Built-in analysis renders Raw vs Cleaned vs Removed — spectrograms, correlation scores, downloadable WAVs of every stage.

The lore

Why Kraken Vinyl Elixir

The name

The Kraken is the legendary deep-sea beast — many arms, working every part of the ocean at once. That's exactly what this engine does to your record: eight arms of DSP reaching into the signal simultaneously — one pulling out clicks, one crushing crackle, one gating hiss, one filtering rumble, one killing hum, and more shaping the tone — all in the same instant, live, as the needle rides the groove.

Why "Elixir"

An elixir is a potion that restores and revives. Old records are full of life but buried under decades of surface noise. Kraken Vinyl Elixir is the potion that brings them back — clean, clear, and alive — without stripping out the warmth and soul that make vinyl worth listening to.

So… go drop a needle. The Kraken's got the rest.

Connect

Turntable into one USB port, powered speakers or a DAC into another. Open the web UI from any browser on your network.

Calibrate

Hit REC / CHECK and play a passage. Kraken auto-tunes the de-click strength so it cleans hard without touching the music.

Listen

Play your records. Watch clicks vanish in the spectrogram, solo what's being removed, and shape the tone with the EQ.

The magic, visualized

What a click actually is

A pop is just a handful of corrupted samples. Instead of muting them, Kraken predicts the true waveform from both sides and rebuilds it — sample by sample.

① A click is just a few corrupted samples

red = the click · teal = predicted & rebuilt · purple = what gets removed

Metering that feels like hi-fi

Ten switchable level displays — from clean digital bars to glowing Soviet tubes. Every one, live:

All ten switch instantly with the ◄ ► arrows in the app, each with a sensitivity trim so they never peg at overload.

Questions

Does it change the sound of the music?
No — that's the whole design goal. Every stage is measured against the original: cleaned audio stays ≈99.9% correlated to the input while removed noise stays near-zero correlated. You can solo exactly what's being taken out and confirm by ear.
What do I need to run it?
A Raspberry Pi 5, a USB turntable (or an RCA→USB ADC), and powered speakers or a USB DAC. The one-line installer sets up everything else.
Is it really real-time?
Yes. Audio flows turntable → Pi → speakers with roughly 48 ms of latency — you won't notice it while a record plays. Nothing is pre-rendered.
Can I hear what it removed?
Absolutely. The Monitor selector solos the removed clicks, crackle, or hiss on their own — so you always know it's pulling out defects, not music.
Why choose Kraken Vinyl Elixir over a store-bought unit?
Store-bought restoration boxes are fixed hardware — you're stuck with whatever converters and processing they shipped. With Kraken Vinyl Elixir you choose your own hardware: run it on the Raspberry Pi and audio interfaces you want, and pair it with our certified ADC/DAC for reference-grade fidelity. Same software brains, but a signal path you control and can upgrade over time.
Why is it called Kraken Vinyl Elixir?
The Kraken is the many-armed deep-sea beast — and this engine reaches into your record with eight arms of DSP at once: pulling out clicks, crushing crackle, gating hiss, filtering rumble, killing hum, and shaping the tone — all in the same instant, live. And an elixir is a potion that restores and revives: it brings old records back clean, clear and alive, without stripping the warmth and soul that make vinyl worth listening to.
Wait… a Kraken? 🐙
Many arms, working every part of the ocean at once — same as the engine works every part of your record. See for yourself:
When does Kraken Vinyl Elixir release?
Q3 / Q4 2026. We're fine-tuning the engine and testing additional hardware so it runs great across more turntables, interfaces and DACs. Hit "Coming Soon" to follow along for the launch.
