Full description
Frequency is an application designed to help users generate and evaluate a wide range of audio frequencies. It can produce tones from 0 to 25,000 Hz, allowing for careful examination of various sound levels. With manual input, users can set specific Hz values rather than relying solely on preset frequencies. This flexibility makes it suitable for tasks like checking headphone response, testing speaker output, or comparing different frequency ranges. The app includes features to test stereo channels, enabling you to confirm whether left and right outputs are balanced. You can also use it to examine bass response, ensuring that low-frequency sounds are reproduced accurately. These functions may be useful for anyone who needs to verify audio performance in headphones, speakers, or other sound systems. In addition to tone generation, Frequency offers a built-in noise meter that provides decibel readings. This feature can help users understand the relative loudness of their environment, whether checking a quiet room or a louder outdoor setting. The app’s decibel readings are based on the device’s microphone input and can be used for simple reference measurements, rather than for professional noise assessments. Frequency also includes a camera mode. In this mode, the device’s camera image is displayed on the screen, while the app simultaneously shows measured decibel values. This allows users to view their surroundings while observing approximate noise levels. For example, this can be useful when examining the sound characteristics of a room while taking note of visual cues in the environment. A newly introduced feature is the Clear Wave function, which generates varying frequency tones that may help loosen dust or moisture in your device’s speaker or microphone. Some users find this helpful after minor water exposure or when debris accumulates over time. Key Features: Frequency tone generation from 0–25,000 Hz Manual input for precise Hz selection Stereo channel testing to check left/right balance Bass response evaluation Integrated noise meter for approximate decibel readings Camera mode with on-screen decibel display for contextual observations Clear Wave function that may help remove dust or water Please note that the decibel measurements are intended as approximate values. They rely on the device’s built-in microphone and may be influenced by device model, protective cases, or background conditions. As such, results should be treated as estimates rather than certified measurements. Disclaimer for Clear Wave: • The Clear Wave feature is intended only as a possible aid to dislodge small particles or moisture. • It does not guarantee resolution of hardware issues or complete removal of dust and water. • Results may vary based on device model, type of obstruction, and other conditions. • If your device has severe water damage or persistent issues, please seek professional repair services. Frequency is intended for general users who wish to explore audio frequencies, check basic stereo configurations, and gain a rough understanding of environmental noise levels. It is not a professional-grade tool, but it can provide helpful insights for casual testing, preliminary checks, or simple experiments with audio signals. Subscription Information: For Unlimited Access to All Features and an ad-free experience, you can subscribe for: $19.99 for a one-year subscription $5.99 for a one-week subscription Your subscription can be managed and canceled at any time through your account settings.
