Struct ssloc::mbss::Mbss

pub struct Mbss { /* private fields */ }

Holds intermediate calculations that can be preserved when locating sound sources using the same array geometry multiple times.

Implementations

impl Mbss

pub fn array_centroid(&self) -> Position

Returns the center of the microphone array.

pub fn analyze(&self, audio: &Audio) -> Array2<f64>

Analyzes input audio and produces [azimuth x elevation] matrix of intensities for each sound source location.

pub fn directional_intensities( &self, intensities: ArrayView2<'_, f64>, threshold: f64 ) -> Vec<(Direction, f64)>

Takes intensities returned by Self::analyze and returns, for those satisfying the threshold, the Direction along with the intensity.

pub fn find_sources( &self, intensities: ArrayView2<'_, f64>, nsrc: usize ) -> Vec<(Direction, f64)>

Findes sound sources in intensities returned by Self::analyze, i.e., Directions that are local maxima and at least MbssConfig::min_angle apart.

pub fn locate_spec(&self, audio: &Audio, nsrc: usize) -> Vec<(Direction, f64)>

Shorthand for mbss.find_sources(mbss.analyze(audio).view(), ...).
