Read full description

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.
