Initializes a new instance of the DXVUMeterNETGDI class

This function converts a tone into its corresponding string value.

Returns the average power at a given frequency

Returns the average power at a given frequency

Returns the frequency at the given FFT index

Returns the "x" (horizontal) position within the control's graphic area given the FFT index

Returns the frequency response at a given FFT index

Returns the FFT index for a given frequency

This subroutine must be called in order to "register" the control and prevent it from displaying the "DEMO" message.

Converts an array of bytes into an array of integers with values ranging from -32768 to 32767 This function is used, internally by the control, but you may also use it when handling the PeakValues event.

Pauses the playback

This is an advanced feature that allows you to use your own buffer provider. When a custom provider is set, DXVUMeterNETGDI will query the provider to obtain the buffer data, instead of using its internal audio monitoring routines. This can be useful if your application is gathering the buffer data from a non standard source or if, for example, you want to plot some data that is not directly provided by a sound card.

Starts monitoring and rendering the monitored audio

Starts playing the file passed as a parameter

Starts recording so the monitored audio will be saved into the file passed as a parameter NOTE: DXVUMeterNETGDI uses the LAME encoder to encode the PCM audio into MP3 format. Please refer to http://www.mp3dev.org/ for more information about the LAME encoder.

Stops monitoring and rendering

Stops playing

Stops recording

Collection of devices, that can record audio, currently available on the system

Sets or returns the quality at which the audio will be monitored

Sets or returns the number of chanels to monitor (1 for mono and 2 for stereo)

Enables or disables the internal rendering engine

When enabled and when the Style property is set to FFT, the control will raise a DTMFToneDown event when a DTMF tone is detected

Sets or returns the size of the data history used to render the FFT

When enabled, the FFT will hold the highest peaks for a few milliseconds This setting is valid for all FFTPStyle values

When enabled, the FFT will hold the lowest peaks for a few milliseconds This setting is only valid for the FFTStyleConstants.Line FFTPStyle

Sets or returns the style used to render Fast Fourier Transform when in Line mode

Controls the decay delay for the peaks

Controls the decay speed for the peaks

This option can be useful to reduce the visual noise that can be generated when rendering a zoomeded plot in log scale This setting is only valid for the FFTStyleConstants.Line and FFTStyleConstants.Filled styles

Sets or returns which scales to render while in FFT mode

Sets or retrieves the font used in the FFT scale

When enabled, the the FFT will leave a small trail behind as it changes This setting is only valid for the FFTStyleConstants.Line FFTPStyle

When enabled, the FFT will display a shaded area showing the valleys and peaks This setting is only valid for the FFTStyleConstants.Line FFTPStyle

Sets or returns the size (bands) of the Fast Fourier Transform

This option controls the smoothing ammount applied to the FFT waveform This setting is only valid for the FFTStyleConstants.Line and FFTStyleConstants.Filled styles

Sets or returns the every time

Sets or returns the windowing type used to render the Fast Fourier Transform

Sets or returns the maximum frequency to be displayed

Sets or returns the minimum frequency to be displayed

Sets or returns the style used to render the X (time) scale

When enabled, the rendered FFT range will occupy the whole width of the control

Allows adjusting the starting frequency of the FFT render without affecting the FFTMin and FFTMax properties

Sets or returns the style used to render the Y (level) scale

Sets or returns the frequency at which the audio will be monitored

Sets or returns the inactive low-level color of the monitored audio

Sets or returns the active low-level color of the monitored audio

Sets or returns the thickness of the lines used to render the Oscilloscope and the FFT when using the Line style

Returns the monitoring state of the control

Sets or returns the number of leds that will be rendered when the Style property is set to DigitalVU

Sets or returns the orientation of the control when the Style property is set to DigitalVU

This property sets or returns the playback position within the file

This property returns the total size of the audio data in the file

Returns the playback state of the control

This property sets or returns the current playback position within the file in hh:mm:ss format

Returns the total playback time in hh:mm:ss format

This property can be used to adjust the volume of the Playback without affecting the Main/Wave output volumes of the sound card

Returns the recording state of the control

Returns the total recording time in hh:mm:ss format

Sets or returns the inactive high-level color of the monitored audio

Sets or returns the active high-level color of the monitored audio

Returns the state of the control

Sets or returns the rendering style that will be used to represent the audio being monitored

Returns the control's version number

Sets or returns the size of the input data (audio signal) history used to generate the FFT

Sets or returns the inactive middle-level color of the monitored audio

Sets or returns the active middle-level color of the monitored audio

Occurs when the control has finished loading and initializing

Occurs when a DTMF is detected

Occurs when a previously detected DTMF is lost

Occurs every time the control encounters a problem

Occurs every time a new FFT frame is calculated. Note that the event will only be triggered if Style is set to FFT

Occurs every time the monitoring state of the control changes

When the Style property is set to UserPaintGDI this event will be fired when the control needs to be painted

Occurs every time a new chunk of audio is monitored

Occurs every time the playback state of the control changes

Occurs every time the recording state of the control changes
