Sound Scope Analyzer

Sound Scope Analyzer visualizes sound from your microphone in real time — an oscilloscope and spectrum analyzer in your pocket.

● Real-Time Mode
• Watch waveforms like on an oscilloscope (a trigger keeps periodic waves steady on screen)
• CRT-style afterglow effect you can toggle on and off
• Frequency spectrum up to 24 kHz with automatic noise-floor removal, so real sounds stand out clearly
• Fixed or auto scaling for each axis; pinch to zoom and drag to pan

● Timbre Mode
• Automatically detects a sustained long tone (like singing “ahh”) and analyzes it with high frequency resolution
• Shows the fundamental note name and frequency, with offset in cents
• Marks each harmonic peak with its note name and measured frequency
• Save the analysis result to Photos as an image
• Sound source presets: voice, whistle, piano, guitar, bowed strings, and winds

● Great for
• Long-tone practice and tone checks for winds, strings, and vocals
• Comparing the harmonic structure of different instruments
• Learning the physics of sound: frequency, waveforms, and harmonics
• Exploring the sounds around you
