This library is focused in working with block of data not on real time processing.

If you are looking for a realtime processing library then there is already great library for it

The folder [examples](https://github.com/klangner/dsp/tree/master/examples) contains demo programs which shows how to use this library.


# Features
   
## Signal generators

Signals generators are nodes with the state. This allows to generate continuos signal across multiple buffers.
Implemented generators:
  
  * [x] Impulse
  * [x] Step
  * [x] Sinusoid
  * [x] Triangle
  * [x] Square
  * [x] Chirp
  * [x] Noise

## Filters

  * [x] Biquad
  * [x] Leaky Integrator (Exponential Smoothing)
  
## Window functions

  * [x] Rectangular
  * [x] Triangular
  * [x] Welch
  * [x] Sine
  * [x] Hann
  * [x] Hamming
  * [x] Blackman


## Frequency domain

  * [x] FFT forward and inverse using RustFFT crate.
  * [x] Find peak frequency
