User reviews

exactly what I needed

useful for identifying frequencies. would be great if there were settings to change bandwidth and export data to CSV

Very Detailed Sound Data In High Resolution

This app is simple, but really nice. Of course the better your mic is, the better it will work. I’m using an iPhone 16 which has a really good microphone, and it can pick up sound frequencies that I can’t even hear with my ears. It’s neat to see the real time sounds being printed on the spectrogram. I suppose if I were to want additional features, it would be the ability to record, and also maybe see a history of one minute or two of past sounds. Other than that, I love it and I feel it was worth $2.

pretty good

it would be nice if i could zoom in more, but still does all i need well enough.

Naja…

Die Anzeige besteht oft nur aus flimmernden Glitches und ist daher nicht wirklich brauchbar. Außerdem verursacht sie sehr viel CPU-Last, sodass sie nur kurz benutzt werden sollte. Alles in allem gibt es bessere Apps für diese Analysen.
Zum Glück war der Kaufpreis nicht so hoch…

Broken! (Frequency bands are not displayed)

This is a very simple app showing a spectrograph, but the frequency bands displayed in the y-axis just show up as boxes with no labels.
