Background As String
Sets or returns the file name of
the image file to be used as a background.
Note that when this property is set to a null string, DXVU Meter
will use the default background.
BackgroundColor As OLE_COLOR
Sets or returns the background
color of the leds.
Calibration As Single
Sets or returns a value which will
be used to amplify the recorded signal.
Note that this value will only affect the rendering engine. The
values returned by the PeakValues event
or the audio recorded by the
StartRecording method will not be affected.
This property should be used to
calibrate the rendering engine using the 1-3-6-9-12-24.wav file
included with the installation.
This wav file will generate a constant 1KHz tone at -1dB, then at
-3dB, then at -6dB, and so on. The factor that makes this wav file
render properly is known as calibration and this value can be any
value from 0.1 to 10.
If the precision of the VU leds is
not a factor, keep this property set to 1.0
Under Windows XP, the SoundBlaster Live! series appear to produce
better results when setting this property to 1.6
EnableRendering
As Boolean
Sets whether the internal rendering
engine should be enabled or disabled.
GreenOFF / GreenON / YellowON /
YellowOFF / RedON / RedOFF As OLE_COLOR
This set of properties set or
return the color to be used in the VU leds, where the property
with the OFF suffix refers to the off state of the led, and
those with the ON prefix refer to the on state of the leds.
FileName
As String
Full path to the file where the
recorded audio will be saved.
It should have the 'wav' extension.
This property is also used to
select a WAV file to be played back.
Orientation As
OrientationConstants
When in VU mode, sets or returns
the orientation of the control.
NumVUs
As Integer
When in VU mode, sets
or returns the number of leds displayed.
This value should never be smaller than 16. Making this value
larger will make the VU mode look better but will considerably
consume more CPU cycles.
PlayBackPos
As Double
When playing a media file this
property sets or returns the playback position.
PlayBackDuration
As Double
After setting the FileName
property this property can be used to retrieve the duration of
the loaded media file.
Quality
As QualityConstants
Sets or returns the sampling
quality used by the control, for the monitoring and recording
operations.
Resolution
As ResolutionConstants
Sets or returns the resolution
used by the Oscilloscope Rendering Engine.
The rcBest setting will produce
the best looking wave forms but will consume more CPU cycles,
while rcVeryLow will produce the worst waveform but while in
this mode, the CPU cycles consumption is almost null.
SavedTime(TimeFormat As
ReturnTimeFormatConstants)
As Single()
Returns an array containing the
duration of the saved audio data.
SoundDriver
As Long
Sets or retrieves the currently
selected sound driver
The list of available sound
drivers is a combination of all recording and playback drivers.
To determine the type of driver use the SoundDriverType property.
SoundDriverCount
As Long
Returns the number of available
sound drivers installed on the host computer.
The number of total drivers is
the sum of input and recording drivers.
SoundDriverName(ByVal
idx as Long) As String
Returns the selected driver's
name
SoundDriverDescription(ByVal
idx as Long) As String
Returns the selected driver's
description (aka friendly name)
SoundDriverType(ByVal
idx as Long) As
SoundDriverTypeConstants
Returns the selected driver's
type.
State As
StateConstants
Returns the current state of the
control.
Style As
StyleConstants
Sets or returns the display mode
of the control.
Version
As String
Returns the version of the
control.
