## What is Oscilloscope Pro Audio Scope?

Oscilloscope is a professional audio analysis app that transforms your iPhone or iPad into a comprehensive audio measurement system. Whether you are a sound engineer, musician, podcaster, or audio enthusiast, Oscilloscope provides the tools you need to visualize and analyze sound with precision.

REAL-TIME OSCILLOSCOPE
View up to 3 seconds of audio waveform history with crystal-clear visualization. Pause playback to examine specific moments, scroll horizontally to navigate through captured audio, and pinch to zoom for detailed inspection. Support for stereo, left-only, right-only, and mono summed display modes gives you complete control over your analysis.

SPECTROGRAM ANALYSIS
Visualize frequency content over time with a professional-grade spectrogram display. The app features a perceptually-accurate Bark frequency scale that mirrors how human hearing perceives sound, making it ideal for music mixing, room acoustics analysis, and identifying problematic frequencies.

STEREO CORRELATION METER
The XY display mode provides a Lissajous-style visualization of stereo phase correlation. Instantly identify phase issues, mono compatibility problems, and stereo width characteristics. The integrated correlation meter shows real-time phase relationship between left and right channels.

FREQUENCY DETECTION
Identify frequencies with precision using advanced pitch detection. The app displays detected frequency in Hz, the corresponding musical note name, MIDI note number, and cents deviation from perfect pitch. Perfect for tuning instruments, analyzing vocals, or identifying resonant frequencies.

TRIGGER MODES
Choose between level-based triggering with adjustable threshold for stable waveform display, or frequency-based triggering for pitch-locked visualization. Lookahead compensation ensures you never miss the transient you are looking for.
