AudioScope: Oscilloscope

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.
