1. SPL Graph works by averaging the SPL for a period of time that can vary from 0. 1 second to 60 minutes, applying an optional weighting filter, and plotting the sound level, recording the raw audio signal, if recording is turned on.
2. SPL Graph is an audio Sound Pressure Level (SPL) environmental noise analyzer, real-time frequency analyzer, chart recorder and data logger.
3. SPL Graph can record up to 24 hours of sound level data, with single second resolution.
4. As the graph runs, the overall LEQ (average SPL) for the entire time period is computed and displayed on the screen.
5. The graph starts with a one-minute plot window, and as a minute is recorded, the graph re-scales automatically and adds another minute to show the data collected so far.
6. You can recall these graphs and bring them up on the screen, and listen to the sounds that were made while the graph was recorded.
7. Swiping across the graph brings up a cursor that displays the exact dB level and time for any point on the graph.
8. You can turn on audio recording, so that you have a record of the sounds that were happening while the graph was being stored.
9. Tap the play button to play back the recorded audio, and you can use the cursor to scrub the audio location on the graph.
10. You can scroll and scale the graph vertically, in dB, by using standard swipe and pinch gestures.
11. Double-tap the screen to zoom out to show the entire graph on the screen.
