Features & Capabilities

The Audio Frequency Counter Chrome extension allows users to precisely measure the frequency of periodic signals captured from their microphone input. Designed for accuracy, it counts signal events when the input rises or falls past a set threshold, then converts these events into frequency or time period readings. Intended primarily for single-frequency signals, it delivers detailed measurements that depend on your device's hardware capacity.

Key features include a dynamic graph displaying the input signal with adjustable time divisions from 2.5 ms/div to 640 ms/div, selectable gate times ranging from 0.1s to 100s, gain adjustment from x1 to x1000, choice of trigger on rise or fall, AC or DC coupling options, and noise level settings to prevent false triggers. While better suited for pure frequency signals rather than complex sounds with harmonics, this tool is ideal for technical applications requiring precise frequency analysis directly through the microphone.

User Reviews

Users generally praise Audio Frequency Counter for its accuracy in measuring pure tones and its straightforward interface. It is effective for testing frequencies in audio devices, meditation sounds, or gadgets. However, performance depends heavily on device hardware, with some users experiencing crashes or limited frequency range readings. The app is simple but can be glitchy or confusing in control usage for some devices. Ads are minimal, and the app can be moved to external storage. Overall, it fulfills its purpose well, especially with pure tones, but may have hardware compatibility issues.

Pros

App provides accurate frequency readings especially for pure tones.
Simple, easy-to-read user interface with clear display of frequency and waveform graph.
Works well for testing audio devices and frequencies used for meditation, healing, or electronic gadgets.
Contains minimal and unobtrusive ads.
Capacity to move the app to external SD memory.

Cons

Performance varies significantly depending on phone hardware; some devices experience freezing or app closure at certain frequency ranges.
Limited to accurately reading pure tones only; struggles with complex sounds or low frequencies below 80-200Hz on some phones.
Some users report glitches or lack of responsiveness on certain devices.
App interface and controls can be confusing, requiring frequent button presses to find the desired function.
One user reported suspicious behavior with phone settings changes, though this seems isolated.

Recent reviews

Amazingly accurate (better than 2 decimal places on pure tones, & usually better than 1 decimal place on CD tracks - varies with CD player), but performance (particularly below 200Hz) varies with phone hardware - on my oldish Motorola it displays waveforms, but only gives a reading between 200Hz & 6kHz, after which it freezes. On a newer IMO it reads from 80Hz to 20kHz, but keeps closing down after about 6kHz, which is quite frustrating. NB: As developer indicates, only works with pure tones.

Does what it says, for whatever you could use an app that counts waveforns over a certain amplitude (with a noise floor adjustment) on. However, unfortunately on my current device, an LG G6, it seems a bit glitchy. This is the first app from this dev I've had problems with. Although this phone has been problematic lately. So the 2 stars lost could be my device and not the app, but that is my experience. And its not enough for me to uninstall practically all the other apps of this dev I have!
