A level indicator view, suitable for use as a level or peak meter, etc.
Set the warning and critical thresholds. If meter value is above either threshold, -warningColor or -criticalColor will be shown, respectively (by default, yellow and red). If -drawsPeak is true warning color will be displayed based on -peakLevel rather than value.
val |
A Float. a = LevelIndicator(bounds:Rect(10, 10, 20, 160)).front; a.value = 0.5; a.warning = 0.6; a.critical = 0.9; a.value = 0.7; a.value = 0.9; |
Sets the style of the view.
val |
An QLevelIndicatorStyle \continuous or \led (see -stepWidth) ( w = Window().front.layout_( HLayout( LevelIndicator().style_(\continuous).value_(1/3), LevelIndicator().style_(\led).value_(2/3), ) ) ) |
The width of each led light, for \led.
val |
An positive Integer. ( w = Window().front.layout_(HLayout( LevelIndicator().style_(\led).value_(0.8).stepWidth_(1), LevelIndicator().style_(\led).value_(0.8).stepWidth_(3), LevelIndicator().style_(\led).value_(0.8).stepWidth_(10), LevelIndicator().style_(\led).value_(0.8).stepWidth_(50), )); ) |
The number of steps used in \led style.
val |
An positive Integer. ( a = LevelIndicator(bounds:Rect(10, 10, 80, 400)).front(); a.value = 1; a.style = \led; a.numSteps = 4; ) |
The number of ticks to display in the view's scale.
number |
An Integer >= 0. ( w = Window(bounds:100@400).front().background_(Color.black); w.layout_(HLayout( LevelIndicator() .numTicks_(16) .value_(0.75) )) ) |
The number of ticks in the view's scale which will be large sized.
number |
An Integer >= 0. ( w = Window(bounds:100@400).front().background_(Color.black); w.layout_(HLayout( LevelIndicator() .numMajorTicks_(16) .numTicks_(16) .value_(0.75) )) ) |
Determines whether the view draws a separate peak display. This can be useful for displaying both peak and RMS values. If drawsPeak is true -warning and -critical will be displayed based on -peakLevel rather than value.
bool |
A Boolean. By default the peak is not drawn. ( w = Window().front().layout_(HLayout( LevelIndicator().style_(\continuous).value_(0.75).drawsPeak_(true).peakLevel_(0.9), LevelIndicator().style_(\led).value_(0.75).drawsPeak_(true).peakLevel_(0.9) )) ) |
Sets the level of the peak display. (See -drawsPeak.)
val |
A Float. ( w = Window().front().layout_(HLayout( LevelIndicator().style_(\continuous).value_(0.1).drawsPeak_(true).peakLevel_(0.3), LevelIndicator().style_(\continuous).value_(0.1).drawsPeak_(true).peakLevel_(0.5), LevelIndicator().style_(\continuous).value_(0.1).drawsPeak_(true).peakLevel_(0.7), LevelIndicator().style_(\continuous).value_(0.1).drawsPeak_(true).peakLevel_(0.9), )) ) |
Sets the color of the meter, as well as the warning and critical colors.
color |
A Color. ( l = LevelIndicator(bounds:Rect(100, 100, 100, 400)).front().value_(1).style_(\led); l.meterColor = Color.blue(0.9); l.warningColor = Color.blue(0.7); l.criticalColor = Color.blue(0.5); ) ( // inverse l.background = Color.blue; l.meterColor = Color.black.alpha_(1); l.warningColor = Color.black.alpha_(1); l.criticalColor = Color.black.alpha_(0.3); ) |
( // something to meter s.waitForBoot({ b = Buffer.read(s, Platform.resourceDir +/+ "sounds/a11wlk01.wav"); x = { var colum, noise, imp, delimp, mul = 1; imp = Impulse.kr(10); delimp = Delay1.kr(imp); colum = PlayBuf.ar(1, b, BufRateScale.kr(b), loop: 1) * mul; // measure rms and Peak SendReply.kr(imp, '/levels', [Amplitude.kr(colum), K2A.ar(Peak.ar(colum, delimp).lag(0, 3))]); colum; }.play; a = LevelIndicator(bounds:Rect(100, 100, 100, 400)).front; a.onClose_({ x.free; o.free; }); o = OSCFunc({arg msg; { a.value = msg[3].ampdb.linlin(-40, 0, 0, 1); a.peakLevel = msg[4].ampdb.linlin(-40, 0, 0, 1); }.defer; }, '/levels', s.addr); }) ) ( a.warning = -6.dbamp; a.critical = -3.dbamp; ) // optionally show peak level a.drawsPeak = true; ( a.style = \led; a.stepWidth = 3; ) // different colors ( a.meterColor = Color.blue(0.9); a.warningColor = Color.blue(0.8); a.criticalColor = Color.blue(0.6); ) // all styles can have ticks ( a.background = Color.clear; a.numTicks = 11; // includes 0; ) // Single blinking square level indicator ( a.style = \led; a.numTicks = 0; a.drawsPeak = false; a.bounds = a.bounds.resizeTo(90, 90); a.numSteps = 1; )
