How It Works

This tool synthesizes audio directly from your chosen settings. Instead of playing a pre-recorded clip, it generates a new waveform each time you click Generate. Because the sound is created mathematically, you can produce a quick 10-second sample for testing or a longer file for an uninterrupted work block.

Each preset uses a different noise curve or texture. White noise distributes energy evenly across frequencies; pink and brown noise tilt energy toward lower frequencies for a smoother, warmer character. The Rain and Café presets layer gentle movement on top of a noise bed so the ambience feels “alive” without becoming distracting.

Step-by-step generation

• Pick a sound: White noise (“szum”), Rain (“deszcz”), Café (“kawiarnia”), plus Pink and Brown noise options for different tonal balance.
• Set duration and volume: Generate short clips for quick comparisons, or longer clips for sustained focus, naps, and travel.
• Choose a sample rate: A lower sample rate keeps files smaller; a higher one preserves more high-frequency detail.
• Optional seed text: Turn on deterministic mode to regenerate the same audio from the same input text and settings.
• Preview and download: Listen in your browser, copy a compact “share settings” string, or download a WAV file for offline use.

Because the output is a standard WAV file, you can also import it into music or video software, trim it to a loop, combine it with other ambience layers, or convert it to compressed formats (MP3/AAC/OGG) with your preferred tool.

Key Features

On-demand sound synthesis

Generate fresh audio instantly instead of relying on repeated loops. The output is created from your settings at the moment you request it, which helps reduce “loop fatigue” for many listeners. This is especially useful for background noise, where tiny variations can feel more natural over time.

Because the sound is synthesized, there are no embedded vocals, ads, or music tracks. You control the level of complexity: a simple “szum” bed for masking, or a textured rain/café ambience when you want something more organic.

Noise types and ambience presets

Different environments call for different masking profiles. White noise is broad and bright, often effective against sharp, intermittent sounds. Pink noise is gentler and commonly preferred for long listening, while brown noise is deeper and softer at the top end—great for low-frequency rumble or when you want less “hiss.”

The Rain preset adds a subtle, airy texture with occasional micro-variations that resemble rainfall. The Café preset aims for a cozy room tone that suggests distance and activity without introducing recognizable speech or melodies.

Deterministic mode with seed text

If you want consistency—e.g., the same rain bed every night—enable deterministic output. The tool uses your input text as a seed so the generated waveform is repeatable when the rest of the settings match. Save your seed phrase (or your share string) to recreate a familiar ambience anywhere.

This mode is also useful for collaboration. If you’re coordinating a quiet co-working session, you can share a single settings string so everyone can generate the same sound profile locally with the same loudness target.

Fast preview + offline WAV download

Listen immediately with the built-in player, then download a standard WAV file that works across devices and apps. Keep it on your phone for travel, store it locally for offline study, or import it into your editor for mixing with timers, guided breathing tracks, or narration.

WAV is uncompressed, which is ideal when you want maximum compatibility and predictable playback. If file size matters, you can convert the WAV to a compressed format after generation while keeping your original as a clean master.

Minimal, privacy-friendly workflow

The generator is designed for quick use: no accounts, no playlists, and no tabs full of videos. You choose what gets created and for how long, making it ideal for short experiments and daily routines. A focused workflow also means fewer distractions when your goal is to concentrate.

Because the sound is produced from your settings, you can keep seed phrases simple and non-personal (for example, “night rain” or “library focus”) and still get a repeatable result.

Use Cases

• Focus and deep work: Mask keyboard chatter, hallway noise, or street sounds while writing, coding, or reading. A consistent bed can make sudden noises feel less intrusive.
• Sleep routines: Create a steady sound bed that helps some people fall asleep and stay asleep by smoothing abrupt noise changes. Try pink or brown noise if white noise feels too bright.
• Studying in shared spaces: Café ambience can make libraries, dorms, and open offices feel calmer and more consistent, especially when combined with a lower volume setting.
• Remote work calls: Use a low-level noise bed in the background of your room (not in the call audio) to reduce the perceived contrast between silence and intermittent household sounds.
• Baby nap time: Many caregivers use gentle noise to mask unpredictable sounds like doors or dishes (always keep volume at a safe level and follow pediatric guidance).
• Meditation and breathing practice: A soft rain texture can support calm attention without distracting melodies. Some people prefer brown noise for a grounding, low-frequency feel.
• Audio testing: Create quick samples for speaker checks, headphone comparisons, or noise-floor evaluations. White noise is also useful for quickly spotting rattles or resonance issues.
• Travel: Download a WAV file to use on airplanes, trains, and hotels where streaming may be unreliable. A familiar sound can make a new environment feel less “alerting.”
• Reading and language learning: A neutral café bed can mimic a public environment while still making your own voice or reading focus the primary signal.
• Creative workflows: Writers and designers sometimes use ambience as a “scene primer.” Rain can feel reflective; café noise can feel energized yet contained.

Whether you call it white noise, “szum,” or simple background sound, the goal is the same: reduce the contrast between silence and interruptions so your brain can stay in a steadier state. The best preset is the one you forget is playing after a few minutes—present enough to soften distractions, but neutral enough to avoid pulling attention away from the task.

For many people, the most effective setup is a moderate volume with a longer duration and minimal interaction. Generate a file once, press play, and let it run while you work. If you want variation without changing your overall feel, keep the preset and volume similar but adjust the seed text.

Optimization Tips

Match the sound to the distraction

High-frequency distractions (like clinking dishes or mouse clicks) are often masked more effectively by white noise because it contains plenty of high-frequency energy. If your environment is more low-frequency (like HVAC rumble, traffic, or distant bass), try brown noise for a warmer, less hissy bed that can blend smoothly with the room.

If you are sensitive to bright hiss, consider pink noise. It often feels more comfortable for long sessions while still providing broad coverage. Rain ambience can also be a good compromise when you want texture without strong tonal elements.

Start quieter than you think

Effective masking doesn’t require loud playback. Begin with a lower volume and increase gradually until sudden noises feel less “sharp.” You should still be able to hear important signals like alarms, doorbells, or someone calling your name.

For sleep and for children, lower volume is especially important. If you’re using headphones, take breaks and keep levels moderate; prolonged loud sound can fatigue your ears even if the sound is “just noise.”

Use deterministic mode for routines and sharing

If you build a habit—work sessions at the same time each day, a nightly wind-down, or a consistent reading hour—deterministic output lets you keep the sound consistent. Save your share string so you can recreate the same settings later with one click.

When you find a combination you love (for example, Rain at 30 seconds, moderate volume, 22.05 kHz), use that as your baseline. Then vary only one parameter at a time if you want to experiment, so you can tell what actually improved the experience.
