Smart Noise Detector helps you capture sounds that stand out from the background. Start monitoring, let the app measure the room for three seconds, and it will record automatically when the sound crosses your chosen threshold. AUTOMATIC RECORDING • Monitor relative sound levels in real time. • Choose a threshold of +12, +18, or +24 dB above the ambient baseline. • Save each sound event as a separate M4A file. • Stop each recording after two seconds below the threshold. • Recalibrate when your surroundings change. • Continue monitoring with background audio support. FIND AND SHARE YOUR RECORDINGS Review recordings by date, time, and duration. Play a recording or tap Share to send the audio file through the iOS share sheet, use AirDrop, or save a copy to Files. Tap Select to choose several recordings or select all, then review the count before deleting. Canceling keeps your selection, and any recordings that cannot be deleted stay in the list so you can try again. ENGLISH AND KOREAN The app supports English and Korean, with English as the default for other device languages. YOUR RECORDINGS STAY WITH YOU Recordings are stored on your device and remain available when you update the app. NoiseDetector does not collect your recordings or upload them to a server. Audio leaves the app only when you choose to share it. Sound levels are relative to your device microphone and are not calibrated sound pressure measurements. Use the app to review everyday sounds, noise events, or barking while monitoring is active.

The clearest difference is price: LF Audio AuralSync at Free against Smart Noise Detector's $0.99.

On in-app purchases and device support there is nothing between them.
