Spectrogram and other features for audio signals

audio-featrs

Audio feature calculation written in Rust.

Example

extern crate audio_featrs;
extern crate ndarray;
extern crate ndarray_rand;
extern crate rand;

use ndarray::prelude::*;
use ndarray_rand::RandomExt;
use rand::distributions::Range;
use audio_featrs::{StftBuilder, PadMode, get_window, Window};

fn main() {
    let size = 10;
    let x = Array1::<f32>::random(Dim(size), Range::new(-1., 1.));
    println!("Signal: {:?}", x);
    let stft = StftBuilder::new()
        .n_fft(size)
        .normalize(true)
        .pad_mode(PadMode::Truncate)
        .hop_length(441)
        .window(get_window(Window::Hann, size, true))
        .build();

    let spec = stft.process(x.as_slice().unwrap().to_vec());
    println!("Spectrogram: {:?}", spec);
}
