Noise Monitor

Record the Noise and Gather the Evidence

Are you subjected to unwanted noise? Quickly set up a monitoring session to record noise. ‘Noise Monitor' has low disk and battery usage with background and screen-locked recording. Long recording sessions well in excess of 12 hours are possible. Noise is analysed by determining the instantaneous audio frequencies of the noise and mapping it onto the colours of a rainbow. On the top instantaneous graph up to 6 frequencies are displayed with the highest intensity frequency in the middle of the line and progressively lower intensities on the outside. The bottom graph is a summary of the entire monitoring session. The vertical bars here summarise an interval with the highest intensity peak colour during the interval at the top of the bar and the next highest shown at the bottom of the bar. Similar noises will show similar colour patterns though higher volume noises will show in brighter colours. The yellow bars at the bottom of each graph show where the app has detected a noise peak. There are fast review features: Visually review noise, selectively replay noisy sections, skip and play noisy intervals, double speed playback. In-app purchases provide a number of extensions: Change the audio frequency range to analyse Capture and email of the monitoring and playback screen Export 16000Hz copies of monitor recordings to Documents or iCloud Drive Email download links to recording copies in iCloud Drive using iOS mail Email of download links to guaranteed unaltered copies Remote monitoring over iCloud drive Emailed periodic updates and noise alerts Alter the conditions that trigger a noise alert
