Sound You Can See !

Sound View is a high-performance Audio Spectrum Analyzer that turns your device into a professional-grade acoustic tool. Whether you are a sound engineer, a music student, or a hobbyist interested in acoustics, Sound View allows you to visualize and analyze sound captured from your built-in or external microphone.

Real-Time Visual Analysis

• See exactly what you hear. Sound View provides a dual-pane interface:
• Spectrum View (Top): Displays frequency strength via intuitive bars.
• Waveform View (Bottom): Shows the raw input signal in real-time. A digital oscilloscope.

High-Resolution Performance

Unlock the full potential of your hardware. Sound View supports frequency ranges from 0Hz up to 96kHz (depending on device capabilities). With sample rates doubling your frequency range (e.g., 48,000 samples/sec for 24,000Hz analysis), you get precision data that goes well beyond the limits of human hearing.

Deep-Dive Navigation

• Freeze & Analyze: Tap once to freeze the display. This allows you to study a specific moment in time without losing the data.
• Precision Zoom: Use the Levels menu to adjust vertical and horizontal magnification for both spectrum and waveform views.
• Swipe to Explore: Zoom in and swipe across the spectrum to pinpoint specific frequency ranges.

Full-Screen Focus: Double-tap either the spectrum or the waveform to expand it to full-screen mode.

Professional Decibel Meter

Track signal strength with the integrated dBSPL (Sound Pressure Level) meter. The app tracks and displays your minimum and maximum decibel levels—perfect for monitoring ambient noise or calibrating equipment. Reset your peaks at any time with a single tap.

Key Features:

• Dual Display: Simultaneous Spectrum and Waveform visualization.
• High Sample Rates: Supports up to 96k (hardware dependent).
• Flexible Orientation: Full support for Portrait and Landscape modes.
• External Mic Support: Compatible with built-in and external microphones.

By selecting the settings button, the Settings view appears.

The magnification slider allows you to control height of the spectrum analyzer bars. Depending on the number of bars configured each spectrum bar represents a different number of frequencies, and therefore its value varies with the number of spectrum bars. Ideally the spectrum bar height would indicate the decibel level of that frequency, however each bar represents a range of frequencies, and it's value is a sum of their decibel levels.

The decay rate slider allows you to control how fast the bars fall back to the bottom of the display. The control gives you full control, as the far left will let the value bar fall immediately, and the far right will not allow it to fall at all.
