How accurate are the measurements from Sound Level & Spectrogram?
While the app is adjusted for iPhone, the built-in microphone's gain can be non-uniform, meaning exact measurements are not guaranteed. The standard noise measurement range is 30-130 dBA.
What are the frequency and time weighting options in Sound Level & Spectrogram?
Sound Level & Spectrogram offers frequency weighting correction (A, C, Z) for different measurement types and time weighting characteristics (Fast=0.125sec, Slow=1.0sec) to capture sound dynamics appropriately.
How often is Sound Level & Spectrogram updated?
The app was last updated on October 10, 2025, with version 3.0. This indicates a recent update, suggesting ongoing development and support from the developer.
What is the age rating for Sound Level & Spectrogram?
Sound Level & Spectrogram has an age rating of 4+. This means it is considered suitable for children aged 4 and above, with no mature content.
Can Sound Level & Spectrogram be used for professional acoustic analysis?
Yes, with features like frequency and time weighting, and a spectrogram for 1/3 octave band analysis, it can be used for applications such as environmental noise measurement, architectural acoustics, and live sound checks.
