Key Features Real-time Spectrum Analysis (See Your Sound) - Instant Visualization: Captures ambient sound via microphone and presents it in beautiful "Line" or "Bar" chart styles, making pitch and volume crystal clear. - Key Data Capture: Displays the current peak frequency and total decibel level in real time, while automatically logging the maximum and minimum decibels for your session. - One-Tap Display Freeze: Tap the spectrum chart anytime to freeze the current frame, allowing you to observe and compare sound details at your own pace. - Multi-Source & Parameter Toggles: Switch between built-in and external microphones with a single tap, and toggle between log/linear frequency axes to suit your needs. - Microphone Gain Control: Easily adjust input sensitivity to your liking. *(Note: This app outputs raw relative values only; for high-precision acoustic measurement, please calibrate with a sound level meter first)* Audio Signal Generation (A Fun Health Check for Headphones & Speakers) - 3 Classic Waveforms: Built-in sine, square, and triangle wave audio signals to instantly turn your phone into a versatile sound transmitter. - Fun Dynamic Frequency Sweeps: Supports fixed frequency playback alongside single, loop, or round-trip dynamic sweep modes. Easily test speaker bass depth or fine-tune audio gear. - Precise Gesture Tuning: Use smooth swipe gestures for silky, precise micro-adjustments to both output frequency and volume gain. Common Use Cases - Measure room insulation or ambient noise decibels at home or in the office. - Test newly purchased headphones or speakers to see if the bass is deep enough and the treble is crisp. - Assist with instrument tuning by viewing the exact sound pitch and frequency. - Explore fun acoustics by playing curious sweep tones with the signal generator.
