For example, how quickly a needle jumps up as the sound level increases.
Specifies the time in milliseconds over which to interpolate as the signal level increases. The following parent options are used in combination with child measures having the Type=RMS option set. Note: To disable all RMS filtering, set both RMSAttack and RMSDecay to 0, and RMSGain as the default 1.0. This is the most meaningful way of measuring audio volume levels in a skin. The result is a value, that when squared, is related (proportional) to the effective power of the signal. The signal value (amplitude) is squared, averaged over a period of time, then the square root of the result is calculated. RMS is a way of calculating the average of values over a period of time, using the mathematical algorithm Root Mean Square.
LEVELATOR RAINMETER PLUGIN WINDOWS
Note: The default audio device in Windows can be changed by using "Manage Audio Devices" from the Windows Start menu. See the DeviceList child measure option for more info.ĭevice IDs will be in the form: To specify a device other than the default, you will need to find the Windows device ID. If you specify Port=Output and no ID, the plugin will connect to the default audio output device defined in Windows.
If not set, it will use the default device for the specified Port. Specifies whether you want to measure the input or output levels for the given device. Parent measure options Port Default: Output Options General measure optionsĪll general measure options are valid. Parent measure options may not be changed dynamically. Note: Only the Type, Channel, FFTIdx and BandIdx child measure options can be changed dynamically with !SetVariable or !SetOption. This child measure gets the current RMS value of the right channel (0.0 to 1.0). This child measure gets the current RMS value of the left channel (0.0 to 1.0). Example: This parent measure processes the default audio output. A single "parent" AudioLevel measure is used to obtain and analyze the audio stream, and then as many "child" measures as desired request data from the parent to get individual values to display in meters. UsageĪudioLevel operates with a "parent / child" approach.
LEVELATOR RAINMETER PLUGIN UPDATE
While the plugin is quite resource friendly and efficient, some care should be taken when deciding how much analysis should be done on the signal, and it is recommended that this plugin be used in a skin dedicated to it, and not as a part of a larger skin where the low update rate may cause higher CPU usage. Note: Creating meters that display sound levels in real-time will require that the skin be set with a fairly low Update rate in the section of the skin. The resulting volume level is returned by the plugin for use in Rainmeter measures and meters. The capture client streams audio data to the plugin where it can be filtered and measured. sound card speaker output, USB audio interface, headphone port, microphone input) It does this by creating a WASAPI capture client in loopback mode. The plugin monitors the amplitude of the post-mixer signal at a Windows audio endpoint. This can be used to create a volume level VU Meter for defined channels, or optionally can filter the audio stream into distinct frequency bands to create a Spectrum Analyzer. The value returned will be a number from 0.0 to 1.0, which will be treated as a percentage for use in meters. Plugin=AudioLevel monitors and analyzes streams of audio sound to or from an audio endpoint.ĪudioLevel will monitor, filter and analyze the amplitude (volume level) of sound input or output on the default or defined device and channels.
