[−][src]Struct iced_audio::param::LogDBParam
A Param
that defines a continuous logarithmic range of dB
values,
with an inflection/stationary point at 0 dB
Values around 0 dB (positive and negative) will increment slower per slider movement than values farther away from 0 dB.
Methods
impl LogDBParam
[src]
pub fn new(
id: u32,
min: f32,
max: f32,
value: f32,
default_value: f32,
zero_normal: Normal
) -> Self
[src]
id: u32,
min: f32,
max: f32,
value: f32,
default_value: f32,
zero_normal: Normal
) -> Self
Creates a new LogDBParam
Arguments
id
- an identifier for the parameter (must be unique!)min
- the minimum of the range in dB (inclusive), must be <= 0.0max
- the maximum of the range in dB (inclusive), must be >= 0.0value
- the initial value of the parameter in dB (ifvalue
falls outside the range given bymin
andmax
, thenmin
ormax
will be used instead)value
- the default value of the parameter in dB (ifdefault_value
falls outside the range given bymin
andmax
, thenmin
ormax
will be used instead)zero_normal
- a normal that defines where on the slider 0 decibels should be. For example,Normal::new(0.5)
will have 0 dB at the center of the slider. Normals of1.0
and0.0
can be used for only negative or only positive decibels respectively
Panics
This will panic if
max
<=min
min
>0.0
max
<0.0
pub fn set_from_value(&mut self, value: f32)
[src]
Sets the parameter's value to value
If value
falls outside the range given by min
and max
from
FloatParam::new()
, then
min
or max
will be used instead.
Value to Normal
calculactions will not be recalculated if the value
has not changed.
pub fn set_from_normal(&mut self, normal: Normal)
[src]
Sets the parameter's value from a Normal
Normal
to value calculactions will not be recalculated if the Normal
has not changed.
pub fn value(&self) -> f32
[src]
Returns the parameter's value
pub fn default_value(&self) -> f32
[src]
Returns the parameter's default value
