Oscilyzer
This app is a combination of oscilloscope, spectrum analyzer and AM/FM synthesizer and works in the audio ranges from 0 ... 22 kHz using the integrated audio interfaces. It offers full support for all systems with iOS or iPadOS with system version 13 or later.

The three operating modes offer a wide range of functions and settings:

Oscilloscope

Very fast image display and real-time triggering
Trigger modes: automatic, normal, single-shot
Trigger edges: rising, falling, both
Automatic measurement of frequency, period and amplitude
Manual measurement of frequency, period and amplitude
Freely selectable trigger level and time
Variable zoom and offset

Spectrum Analyzer

Very fast image display with the help of Apple Metal graphics acceleration
Logarithmic or linear frequency axis
Display modes: spectrum, waterfall and combined
Automatic determination of the dominant frequency
Music note calculation of the dominant frequency
Possibility to transfer the dominant frequency to the generator/synthesizer
Cursor for manual frequency determination
Adjustability of bandwidth, FFT window and high-pass filter
Adjustability of color scheme, brightness and contrast of the waterfall display

Synthesizer

Waveform synthesis in real time
AM and FM modulation
Different waveforms for base signal, AM and FM modulator
Multiple memory locations for quick switching between different settings
Direct input of all numerical parameters
