o46scope vs Sound Scope Analyzer

o46scope is an audio measurement app for iPhone and iPad that helps you visualize sound in real time. It supports oscilloscope and FFT spectrum display, allowing you to inspect waveforms and frequency components instantly. The app also supports internal signal generation with Tone1 / Tone2 and test signal (Beep) output, making it useful for quick checks, learning, and simple audio measurement tasks. Key features • Oscilloscope display • FFT spectrum display • Signal tab for signal control • Internal signal generation with Tone1 / Tone2 • Speaker output for tones • Test signal (Beep) output • Adjustable parameters Premium Tone1 / Tone2 internal signal generation is available as a premium feature. It is available without ads. Ideal for users who want waveform visualization, frequency analysis, and signal generation in one app. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

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 ● Privacy All audio is processed entirely on your device. Nothing is ever recorded, stored, or transmitted. Available in English and Japanese.
