Meet the RTV Silence Detection

RTV Silence Detection monitors the noise level (modulation) by continuously measuring the number of decibels (dB) and warns if a decibel too low is measured consecutively, according to a set time period. This will result in too soft audio or silence. Warning is done by e-mail and/or SMS. It is also possible to run an external program or script at the moment of detection or to send an API request to a url. When the sound level is detected again (decibel is higher than indicated for a minimum period of time), this is also warned. Also then an external program, script or API call can be executed. Modulation is detected via a recording source of a sound card. Program contains many possibilities with a.o. an extensive log system, planning program for when to detect and when not to detect and can detect multiple sources at the same time (per source a separate version). A shareware version is offered which detects a maximum of 30 minutes. After purchasing a license the detection runs 24 hours a day.
