Crackle: Lo-Fi Vinyl Sync

Transform any track into a cozy lo-fi masterpiece!

Crackle is an atmospheric background noise generator that works over your favorite music players (Spotify, Yandex Music, Apple Music, VK Music, and others). Just turn on your music, launch Crackle, and enjoy the warm, tube-like sound.

🎧 Perfect Sound Overlay
The app doesn't pause your music. It gently blends the sound of an old record, the sound of rain, or the crackle of a campfire directly into your audio stream. Perfect for concentration, studying, working, or meditating.

🤖 Smart Pause (Smart Sync)
Crackle can listen to your system: the vinyl will hiss only when your music is playing. Pause a track? The vinyl will smoothly fade out along with it. Play the next track? The needle will drop back down.

🌧 Two independent sound layers
Create your perfect atmosphere by mixing two layers:

Vinyl (Reacts to music): Choose from the soft hiss of a new record (Mint) to the aggressive crackle of an old gramophone (Scratched).
Ambient (Continuously plays): Add the cozy sound of rain, the roar of the ocean, or classic white noise to the background for maximum focus.

🎛 Complete control
Adjust the volume of each layer separately. Make the rain loud and the crackle of vinyl subtle, or vice versa. All your settings and selected presets are saved automatically.

🌙 Runs in the background
Turn off your screen or chat on messengers—Crackle will continue to create a cozy atmosphere in the background, draining almost no battery.

What is Crackle good for?
• Transforming ordinary tracks into lo-fi / chill-hop.
• Deep concentration (Deep Work) and studying.
• Stress and anxiety relief (ASMR).

No complicated settings. Just you, your favorite music, and the magic of analog sound.
