Struct AnalysisMetadata 

pub struct AnalysisMetadata { /* private fields */ }

Metadata needed to interpret one live Analysis snapshot.

Implementations

impl AnalysisMetadata

pub fn new( sample_rate: f32, fft_size: u32, min_decibels: f32, max_decibels: f32, smoothing: f64, ) -> Self

pub fn sample_rate(self) -> f32

Effective sample rate of the audio graph, in hertz.

pub fn fft_size(self) -> u32

Number of time-domain samples in each snapshot.

pub fn frequency_bin_count(self) -> u32

Number of frequency values in each snapshot.

pub fn frequency_bin_width(self) -> f32

Width of each frequency bin, in hertz.

pub fn frequency_for_bin(self, bin: u32) -> Option<f32>

Center frequency represented by bin, or None when it is out of range.

pub fn min_decibels(self) -> f32

pub fn max_decibels(self) -> f32

pub fn decibels_for_frequency_value(self, value: f32) -> f32

Convert a normalized byte-frequency value to its configured decibel value.

pub fn smoothing(self) -> f64

Frequency-domain smoothing time constant in the inclusive range 0.0..=1.0.
