Pixel Pulse: Sound & dB Meter

Pixel Pulse is an application that turns your device into a professional Sound Level Meter (SPL) and Noise Dosimeter. It has a beautiful and user-friendly interface that offers the best audio analysis experience on Android. The core features of the app are completely free, unlike other apps that hide essential tools behind a paywall.

The app includes a professional dB Meter that allows you to visualize sound levels instantly with a responsive and expressive gauge. You can also record, save, and replay as many audio sessions as you need, with no limits on duration or quantity. The interactive history feature allows you to review past recordings with detailed stats and scrub through waveforms to pinpoint the exact moment a loud noise occurred. The Material You design of the app adapts to your wallpaper's colors and supports both Light and Dark modes. Additionally, the app is privacy-focused, as it only records and stores decibel levels, keeping your data 100% on your device.

If you want to take your audio analysis to the next level, you can upgrade to Pixel Pulse+ (Pro Toolkit). This advanced toolkit is designed for professionals and health-conscious users. It includes a Hearing Health Guardian (Dosimeter) that allows you to track ambient noise levels periodically throughout the day without keeping the app open. You can also follow WHO/NIOSH guidelines with a visual weekly "Noise Budget" to prevent hearing fatigue and get notified immediately if you are exposed to harmful noise levels for too long.

The Pro Toolkit also offers professional technical tools such as Frequency Weighting, which allows you to switch between A-Weighting (human hearing), C-Weighting (industrial/bass), and Z-Weighting (flat response). You can also export full raw data points to Excel/Sheets for professional reporting and adjust the update rate (Fast, Normal, Slow) to suit your measurement needs.

For advanced customization and insights, the Pro Toolkit includes features like Image Export, Ambient Haptics, and Smart Analysis. You can share beautiful charts and session summaries directly to social media or clients, feel the sound intensity through dynamic vibration feedback, and unlock Daily, Weekly, and Monthly exposure charts to spot long-term trends. The Pro Toolkit also offers exclusive themes, including a pure black AMOLED mode.

The app is optimized for phones, foldables, and tablets, and also includes a standalone Wear OS app with complications and tiles for wrist-based monitoring. Download Pixel Pulse today to measure your world and protect your ears.
