Oscilloscope
Transform 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, scroll, and pinch to zoom for detailed inspection with stereo, left, right, and mono display modes.
Spectrogram Analysis
Visualize frequency content over time with a perceptually-accurate Bark frequency scale that mirrors human hearing—ideal for mixing, room analysis, and identifying problematic frequencies.
Stereo Correlation Meter
XY Lissajous-style visualization shows stereo phase correlation instantly. Identify phase issues, mono compatibility problems, and stereo width characteristics at a glance.
Frequency Detection
Advanced pitch detection displays frequency in Hz, musical note name, MIDI note number, and cents deviation from perfect pitch. Perfect for tuning and identifying resonances.
Trigger Modes
Level-based triggering with adjustable threshold for stable waveform display, or frequency-based triggering for pitch-locked visualization. Lookahead ensures you catch every transient.
Professional Features
Support for all audio inputs, AUv3 plugin for DAWs, stereo meters with peak hold, adjustable time windows, and high-resolution display optimized for all iOS devices.
Key Features
