Tone Gen Pro vs Signal Scope Studio

Generate audio signal of different shapes with many parameters and options. You can generate frequencies up to 20 kHz of audio signal. If you are curious student about sound after a physics class, music instruments hobbyist/professional, a teacher, or a professional in audio equipment, this app is for you ! You can generate: - Single type signal (sinusoidal, square, noise, etc) - Sweep (chirp) signal (linear or exponential) - Click: ON-OFF sine wave with any duty cycle and ON frequency - Merged sound of any number of tones or sweeps

Signal Scope Studio combines a dual-channel oscillator, an output signal simulator, a live microphone oscilloscope and spectrum analyzer, and a stereo decibel meter in one audio toolkit. DUAL SIGNAL GENERATOR • Set sine, square, triangle, falling sawtooth, or white noise independently for LEFT and RIGHT • Adjust frequency from 20 Hz to 20 kHz and volume from 0 to 100% with 270-degree dials. Frequency also supports numeric entry • Adjust left and right frequency and volume independently, or link them while preserving the ratios at the time linking is enabled • Output different frequencies from the left and right channels to produce beats and other effects OUTPUT SIGNAL SIMULATOR • Linearly sum LEFT + RIGHT internally and display the waveform and spectrum together • Adjust Auto Trigger, freeze/resume, vertical and horizontal zoom, and refresh interval • Control frequency range, spectrum sensitivity, and FFT resolution with dials or pinch and pan gestures • Save high-resolution graphs with a dark navy background, white text, and green traces to Photos WAVESCOPE • Display the time-domain waveform and frequency spectrum of microphone input together in real time • Use Auto Trigger, freeze display, pinch zoom, and a movable settings window • Open Dual Signal Generator within the app and measure the actual sound emitted by the same device DECIBEL METER • Display relative microphone input levels on analog-style VU meters in real time • Automatically detect stereo or mono input: two separate meters for the left and right channels in stereo, or one meter in mono • Use PEAK indicators to spot brief sounds near the maximum input level • Save a calibration offset to match a commercial decibel meter MORE • All features are available for seven days from the original download date. After the trial, Dual Signal Generator and Decibel Meter remain free to use; a one-time purchase lets you continue using WaveScope. • Includes detailed offline manuals in Japanese, English, and French. • Supports iPhone and iPad in portrait and landscape. PLEASE NOTE • Measurements depend on the device and environment. • This app is intended for education, experiments, and general audio checks. It is not a substitute for calibrated instruments, certified sound-level meters, or medical devices.
