Audio Frequency Counter vs Sound Spectrum Pro Usage & Stats

Frequency counter based on the microphone input. Counts when the input rises or falls past a set level and converts into into frequency or a time period. FOR INDICATION ONLY. Results depend on your device and its hardware. If you just want to know the frequency of a sound with harmonics (e.g. musicial instrument), a FFT based app such as keuwlsofts spectrum analyser or guitar tuner will be better. This app can provide more accurate frequency measurement for single frequency input signals. Features include: Display of triggered event count and frequency or time period. Graph of input signal, 2.5 ms/div up to 640 ms/div. Gate time of 0.1s, 1s, 10s or 100s. Gain from x1 to x1000. Trigger on rise or fall. AC or DC coupling. Set a noise level so new event is not triggered until the signal has first passed this level. More details can be found on the website.
