Struct ShortSpectrum 

pub struct ShortSpectrum { /* private fields */ }

One channel’s short-window linear magnitudes, and nothing else.

The per-channel half of the stereo field (ADR-0215) reads its band energies through BandSplitter, which reads the short window’s magnitudes alone — so a per-channel pass needs neither the long window nor the log-band axis. A second SpectrumAnalyzer per channel would plan an 8192-point FFT and carry its ~120 kB of buffers for nothing.

Every buffer is heap-held, including the taper: Analyzer keeps two of these and is constructed and moved by value.

Implementations

impl ShortSpectrum

pub fn new() -> Self

Plan the short FFT and precompute its Hann taper.

pub fn analyze(&mut self, window: &[f32]) -> &[f32]

FFT window and return its linear magnitudes, on the same amplitude scale SpectrumAnalyzer::magnitudes publishes — so a band mean taken from these is comparable with the mono one bin for bin.

A window shorter than WINDOW_SIZE leaves the tail of the transform zeroed rather than panicking, exactly as the long window’s fill does.

Trait Implementations

impl Default for ShortSpectrum

fn default() -> Self

Returns the “default value” for a type.
