# DAFX experiments

Reading the book [Digital Audio Effects(DAFX)](https://www.amazon.com/DAFX-Digital-Effects-Udo-Z%C3%B6lzer/dp/0470665998), and implementing the synthesizers, filters and effects.

# Goals

- *Correctly* implement all the effects in the book and other common effect that are not present in the book but a *reliable implementation* can be found, using its original implementation or other simpler and faster implementations.

- *Visualize* as much as possible to get a better understanding of the underlying algorithm. 

- *Simple and Easy to Understand*, we use Python to make the code simpler and easier to understand.

- We can *interactively* changing the parameters and see what happens. To achieve it, we use Jupyter as our UI.

# Non-goals

- This is not a project for production use, so performance is not our main goal, as long as it does not affect playability.

- Real time rendering is not our goal, either.

# Done

- Basic stuff

	- Channels and connections(like in any DAW)

	- Complex number intermediates

	- Impulse response plotting 

	- Spectrum plotting

- Synthesizers

	- Simple oscillators(Sine, Saw, Noise)

	- Sampler

- Filters and Delays

	- Comb filter(delay line), GrossBeat

	- IIR filter

	- Vibrato, Echo, Slapback, Flanger

- Modulators

	- Single Side Band

	- Ring Modulator

	- Amplitude Modulator

	- Phase Modulator

	- Frequence Modulator

- Non-linear Processing

	- Limiter

	- Compressor

	- Expander

# TODOs

	- Wah-Wah Filter, Bell

	- Time/Frequency Warping
