Vinyl Crackle Mixer — GROOVE ATLAS
VINYL CRACKLE MIXER / THE RECORD REMEMBERS
Vinyl Crackle Mixer — Make time audible.
A speck of dust. A line through the grooves. Build a record, give it a past, and listen to what remains.
SYNTHETIC SOUND · LOCAL PROCESSING · FREE WAV EXPORT
Choose Etch, then draw on the record. Dust near the selected groove and scratches crossing it sound when they meet the needle.

Listen
Choose a pressing and drop the needle. Begin with a low output level.
Etch
Place dust or draw a scratch. The mint ring marks the groove currently read by the needle.
Compare
Treat removable contamination, then compare A/B. Permanent scratches and wear remain.
Every pressing has a past.
Begin with a record from the archive. Four creative interpretations of equipment, materials, and the ways we care for them.
Creative models, not historical measurements. An older record is not necessarily a noisier record.
Anatomy of a crackle
Waveforms below illustrate each sound’s character. The scope under the turntable shows the actual output. Return to the full mix after solo listening.
Surface hiss
Continuous fine surface noise.
Micro crackle
Tiny, irregular dust impulses.
Clicks & pops
Short, distinct impact sounds.
Motor rumble
Low-frequency mechanical vibration.
Wow & flutter
Slow and fast pitch instability. Load music to hear it.
Electrical hum
A steady mains-frequency tone.
The Aging Machine
Years do not equal damage. Explore a fictional handling and storage scenario, from a carefully kept record to a heavily used pressing.
A creative condition model, not a calendar.
The Restoration Bench
Cleaning can remove loose contamination. It cannot undo a permanent scratch or rebuild a worn groove. Compare the same seeded noise at the same playback position.
Your music, repressed.
Open an audio file you have permission to use. It stays in this browser; it is never uploaded by this tool. Choose a duration and export a 44.1kHz stereo WAV mix or noise alone.
Noise only · no music file needed to begin.
Noise Detective
The science of imperfection.
GROOVE ATLAS is an independent interactive sound experiment. The engine synthesizes noise and maps drawn defects to a selected circular groove. It is a simplified teaching model, not a physically exact spiral-groove simulator. Era presets are creative interpretations, not historical measurements. No music samples are bundled. The optional demo chord is synthesized locally. Noise is seeded for repeatability; it is not a recording of a particular record.
Why does vinyl crackle?
Loose contamination and surface defects can disturb stylus motion, producing short impulses. Continuous hiss, low-frequency rumble and electrical hum have different causes and should be adjusted separately.
Will cleaning remove every click?
No. This experiment reduces removable dust and static-related noise. Permanent scratches and groove wear remain. The buttons model relative changes; they are not instructions for a real cleaning product.
What are wow and flutter?
Slow and fast playback-speed variations modulate pitch. Load an audio file to hear this clearly; noise alone has no stable musical pitch.
Can I reproduce my record?
Save the JSON project to preserve the seed, controls, defect positions, cleaning state and RPM. Import the same audio file separately. Choose a 12, 30, or 60-second WAV. Live playback loops six revolutions at the selected RPM and uses the beginning of your imported audio.
Is this free and private?
The tool requires no account and processes selected audio locally. Browser memory limits and supported audio formats vary. Ads and the Blogger platform have separate data practices.
