Struct Level 

pub struct Level {
    pub peak: f32,
    pub rms: f32,
    pub dc: f32,
}

Peak and RMS level of a block of samples, relative to full scale.

Fields

peak: f32

Largest absolute sample, 0.0..=1.0 of full scale.

rms: f32

Root-mean-square, 0.0..=1.0 of full scale.

dc: f32

Mean sample value (DC offset), -1.0..=1.0 of full scale.

Implementations

impl Level

pub fn measure(samples: &[i16], offset: usize, stride: usize) -> Self

Measures every stride-th sample starting at offset. Use (0, 2) for the left channel of interleaved stereo, (0, 1) for mono.

pub fn rms_dbfs(&self) -> f32

RMS in dBFS (0 dBFS = full scale); -inf for digital silence.

pub fn peak_dbfs(&self) -> f32

Peak in dBFS.

Trait Implementations

impl Clone for Level

fn clone(&self) -> Level

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Level

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Level

fn default() -> Level

Returns the “default value” for a type.

impl Format for Level

fn format(&self, f: Formatter<'_>)

Writes the defmt representation of self to fmt.

impl PartialEq for Level

fn eq(&self, other: &Level) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
