Oscilyzer app for iPhone and iPad

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.
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
