Signal Scope Studio

Signal Scope Studio combines a dual-channel signal generator, output signal simulator, and microphone-input oscilloscope and spectrum analyzer in one audio toolkit.

Signal Scope Studio is an all-in-one audio toolkit combining a dual-channel signal generator, an output signal simulator, and a microphone-input oscilloscope and spectrum analyzer.

DUAL SIGNAL GENERATOR • Configure sine, square, triangle, falling sawtooth, or white-noise output independently for the left and right stereo channels. • Adjust frequency from 20 Hz to 20 kHz and volume from 0% to 100% with rotary dials. Exact frequencies can also be entered numerically. • Set frequency and volume independently for each channel, or link the channels while preserving the current left-to-right ratios. • Because the two stereo channels produce sound independently, you can create effects such as acoustic beats by using nearby frequencies.

OUTPUT SIGNAL SIMULATOR • Combine the left- and right-channel signals internally without sending them through the speakers, and display the resulting waveform and spectrum simultaneously. • On the oscilloscope, configure Auto Trigger, freeze the display or resume measurement, vertical and horizontal zoom, and refresh interval. • On the spectrum analyzer, configure freeze the display or resume measurement, measurement frequency range, input sensitivity, resolution, and refresh interval. • Adjust settings intuitively with rotary dials and use pinch/pan gestures on the graphs to change the displayed ranges. • Save screenshots of the oscilloscope and spectrum-analyzer graphs to your photo library.

WAVESCOPE • Display the waveform and spectrum of audio captured by the device microphone simultaneously in real time. • On the oscilloscope, configure Auto Trigger, freeze the display or resume measurement, vertical and horizontal zoom, and refresh interval. • On the spectrum analyzer, configure freeze the display or resume measurement, measurement frequency range, input sensitivity, resolution, and refresh interval. • Open Dual Signal Generator inside WaveScope to generate sound and measure it on the same device. Because the microphone captures the actual sound from the device, the waveform and spectrum reflect the complete signal path, including device output, speaker response, propagation through air, nearby reflections, and microphone input. Harmonics can be identified in the spectrum.

TRIAL AND PURCHASE • All features are available for seven days after download. • Dual Signal Generator remains available after the trial period ends. WaveScope can be unlocked with a one-time purchase. • If you have already purchased access, tap Restore Purchases to restore it.

OTHER • A detailed manual is available in Japanese and English. • Supports iPhone and iPad in portrait and landscape orientations. The app is localized in Japanese and English.

NOTE This app is intended for education, experimentation, and inspection of audio information such as waveforms and spectra. It is not a calibrated measuring instrument or medical device.
