Audio Frequency Counter 1.15

This app is a frequency counter that is based on the microphone input. It is designed to count when the input rises or falls past a set level and then convert it into either frequency or time period. However, it is important to note that the results provided are for indication purposes only and may vary depending on your device and its hardware.

If your main goal is to determine the frequency of a sound that has harmonics, such as a musical instrument, it would be advisable to use a FFT-based app like keuwlsoft's spectrum analyzer or guitar tuner, both of which are available for free. These apps will provide more accurate frequency measurements for signals with multiple frequencies.

However, if you need more precise frequency measurements for single frequency input signals, this app can be quite useful. It offers several features that include:

• Display of triggered event count and frequency or time period
• Graph of the input signal with adjustable time divisions ranging from 2.5 ms/div up to 640 ms/div
• Gate time options of 0.1s, 1s, 10s, or 100s
• Adjustable gain settings from x1 to x1000
• Ability to trigger on rise or fall
• AC or DC coupling options
• Noise level setting to prevent triggering until the signal has passed a certain level
