The settings are divided into the following categories:

The general settings are general application settings.

The sound card settings indicates which sound card and recording source should be used.

The Silent settings sets when silence alarm should be given, and when modulation is detected again.

The alarm settings specifies what should happen when silence is detected and/or when modulation is detected again during silence.

Inally the planning program allows you to enter time periods for when the application should or should not detect.

General settings

These are the settings for the application in general.


The first option indicates whether detection should be started immediately when starting the application. This only works with a user license.

The second option indicates whether the application should be placed as a system icon in the system part of Windows (usually this is the space in the Windows clock at the bottom right).

The second part is settings related to the log files. RTV Silence Detection keeps log files of the activities that have taken place (e.g. silence that has been detected, starting the application, etc.). A separate log file is created for each day.

Clicking "Customize" will change the location for the log files.

Sound card settings

Here you select which sound device should be used for detection.

You can select from two type drivers:

  • ASIO

  • Default (this is Windows Multi-channel Audio System WASAPI)

Then you can select a soundchannel for detection. For default you can select for loopback of capture.

Silence settings

The silence settings determine when silence is detected and when modulation is detected again after silence.

The first part indicates when the modulation / silence is too soft.

There are three settings that can be adjusted:

The quiet limit is in decibels (dB). When the modulation falls below the dB limit, there is silence. As soon as this is the case, a timer runs down to zero. At zero a silence alarm is triggered.

When during the countdown the modulation rises above the dB limit, the timer is reset to the start value.

When the timer should countdown to zero is set at minutes and seconds.

Inally, you can also select whether to detect on the left or right channel or by averaging both channels.

The advice is to choose both left and right. As soon as a channel fails (modulation via 1 channel is detected), this will also be detected (the timer will also drop to zero).

In the second part of the screen is set when the modulation is detected again. In this case, there is when the number of decibels remains continuously above the set Db limit. When this is the case, the silence alarm is aborted and the application starts detecting again.

The time entered here is in milliseconds. 1000 milliseconds is 1 second.

For example: if 3000 milliseconds is set (3 seconds), and modulation of at least 3 seconds is detected continuously, the silence alarm is aborted.


The application contains two ways to perform actions:

- when silence is detected (timer reaches zero)

- during silence modulation is detected

Actions when silence is detected

When silence is detected, the following actions can be performed:

- Sending an SMS (see next chapter).

- Sending an email message (see next chapter).

- (It is also possible to send an email repeatedly as long as silence is detected).

- Beep through the built-in speaker.

- And executing a program or script with possible parameters.

Actions when modulation is detected again

As soon as the modulation is detected again, the following actions can be performed:

- Close the alarm window. By default this option is on. If this option is turned off, and modulation is detected, the alarm window will not disappear. This will show that silence has been detected earlier.

- Sending an SMS (see next chapter).

- Sending an email message (see next chapter).

- Beep once via the loudspeaker.
This is lower in tone than silence. This way you can immediately hear that modulation is detected again).

- Run a program with any associated parameters.


The planning section of the silence detection can be used to set which time periods should or should not be detected.

At the top it is indicated whether the set time periods should be detected or not.

After that one or more time periods can be set. Periods can be set to period:

- On a time period of date and time (not periodic)

- Periodically every week, monthly or yearly with time period.

During detection, the application will indicate when detection is stopped or restarted.

If alarm detection is in progress and the planning program indicates that there is no more to be detected, the alarm detection will also be stopped.
