1. Also, check out our other great audio and acoustics apps: AudioTools, our premier suite of audio and acoustics analysis apps, SPL, SPL Graph, for recording SPL over time, RTA, RT60, Generator, and Speaker Pop.
2. Adjust the decay time from 0.5 seconds, for a very fast fluid display, to 8 seconds, or use Peak Hold or Average mode.
3. The signal generator appears as a heads-up display when you tap the icon, so you can see the graph while you adjust the generator.
4. When your analysis is complete, you can save the graph image to your photo roll to include in a report, or export the data in an XLS file.
5. You can control both the level of graph smoothing and decay time, to get as much or as little detail as you require.
6. This application has been designed for acoustics work, and so the bins have been normalized to octaves, to get a display that will show a flat line for pink noise.
7. Set the FFT size from 4096 to 32k points (depending on iOS device) , or select Equal Points Per Octave mode, for high-resolution analysis, even at low frequencies.
8. Turn on Peak Tracking to have FFT automatically find a label the frequency of the highest peak on your graph.
9. It uses the Fast Fourier Transform to analyze incoming audio, and displays a very detailed graph of amplitude vs.
10. Use a stored graph as a baseline that is subtracted from the current graph in real time.
11. You can also control the dB resolution of the graph, as well as the frequency range that is displayed.
