About this app

AudioScope is the most accurate audio oscilloscope, waveform viewer, and signal scope for Android. It turns your phone into a real-time time-domain oscilloscope that draws the live microphone waveform on a smooth, responsive display.

▶ MAIN FEATURES
• Real-time microphone waveform on a live trace
• True time-domain oscilloscope view
• Adjustable time/div and amplitude (volt) scale
• Trigger and hold to freeze a stable waveform
• Peak amplitude readout
• Mono input from the built-in or external mic
• Smooth 60fps display
• Clean dark mode for any lighting
• Works fully offline, no account needed

▶ HOW TO USE
1. Open AudioScope and allow microphone access.
2. Point the mic at your sound source.
3. Adjust the time/div scale to stretch or compress the waveform.
4. Adjust the amplitude scale to fit the signal vertically.
5. Tap trigger and hold to freeze a stable trace for inspection.

▶ WHO USES IT
• Audio and electronics engineers checking live signals
• Musicians inspecting tone and waveform shape
• Hardware and DIY makers debugging circuits
• Physics and DSP students studying sound
• AV technicians verifying audio on site

Allow the microphone permission to begin. External USB microphones are supported for higher-quality input.
