#Logging spl smaart v8 upgrade

SPL Graph can record up to 24 hours of sound level data, with single second resolution. With iPrecisionMic, you can send the system in to our calibration lab and get a calibration certificate for ISO 61672 and ANSI S1.4.

To upgrade the app to true professional standards, add our iTestMic, iPrecisionMic, or iAudioInterface2 with an appropriate microphone, and get ANSI or ISO Type 1 or 2 results. The app works very well with the built-in iOS device microphone. 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.ДЇor sound intervals of 1.0 second to 60 minutes, the optional octave and 1/3 octave logging modules allows storing the spectrum of the sound, for each interval. * Start another plot after auto-saving for continuous operation * Auto-save results after set intervals, and email the results to you

* Email notifications when sound exceeds pre-set limits * Calculate Ln SPL values, L01, L10, L50, L90, L95, LMax and LMin * Show a 3D Plot of octave or 1/3 octave results

* Do octave and 1/3 octave band analysis (optional in-app purchase) * Capture video of events (optional in-app purchase) * Record audio while plot is running, playback to identify sounds that may have caused problems SPL Graph is an audio Sound Pressure Level (SPL) environmental noise analyzer, real-time frequency analyzer, chart recorder and data logger.
