# Sirena

Digital audio signal processing primitives.

Components of the project include:

* Signal abstraction used to abstract samples into infinite-iterator-like
  objects. It also includes basic signal generators and trait allowing
  implementation of custom signal processors.
* Ring buffer of arbitrary size, allowing to read discrete or interpolated
  samples.
* Spectral analyzer, using FFT to measure harmonic spectrum of given signal.
  Mostly meant for testing.
* State variable filter, can be used for low/high/band pass or band reject.

# Razor

* `#[no_std]`, targetted for embedded systems.
