Magspec

magspec is a Short-Time Fourier Transform (STFT) library written in Rust, designed for speed, safety, and high-quality spectral analysis.

It provides fast STFT execution for f32 and f64, flexible window types, customizable hop sizes, and utilities for generating magnitude- or power-based spectrograms.

Example

let stft_plan = Magspec::make_forward_f32(StftOptions {
    len: 256,
    hop_size: 32,
    window: StftWindow::Blackman,
    normalize: true,
})
.unwrap();
let stft_result = stft_plan.execute(&signal)?;
// optionally draw spectrogram using spectrograph
use spectrograph::{Normalizer, SpectrographOptions, rgb_spectrograph_color_f32, SpectrographFrame};
let scalogram = rgb_spectrograph_color_f32(&SpectrographFrame {
    data: std::borrow::Cow::Borrowed(stft_result.data.borrow()),
    width: stft_result.width,
    height: stft_result.height,
    }, SpectrographOptions {
    out_width: 1920,
    out_height: 1080,
    normalizer: Normalizer::LogMagnitude,
    colormap: spectrograph::Colormap::Turbo,
})?;
