Guitar effects and amp modeling
For my guitar setup I’ve been using Guitarix on my laptop to simulate effects and amps. Recently I started seeing lots of references to ‘Neural’ in regards to guitar effects and amp modeling (Neuraldsp / Neural Amp Modeler) so I decided to see whats this all about. It turns out you can train a Neural network to simulate the behavior of a guitar amp and effects. The idea seems to be to create a clean tone with several variations, pass that clean tone through a real amp and effects setup and train a Neural network to learn the behavior of the real setup. In this way you can have different network networks that simulta different setups which you can later combine.

- NEURAL AMP MODELER - Neural Amp Modeler is an open-source project that uses deep learning to create models of guitar amplifiers and pedals with state-of-the-art accuracy.
- History of NAM
- NAM Source Code - The NAM has 3 components:
- NAM-Training - This repository holds the machine learning code used to make new models.
- Core DSP - This repository contains the low-level DSP code for playing NAM models in real time.
- Plugin - This repository integrates the core DSP with the iPlug2 framework to create plugins (VST3, AU) and a standalone desktop application.

- Tonehunt models - Share your models with other NAM users and find others’ models on ToneHunt, a community-organized online library.
- NAM for users - Here you’ll find everything you need to get into NAM, from making your own models to getting connected with tens of thousands of other musicians enjoying NAM.
- Neural Amp Modeler - Model Training Notebook - A Google Colab notebook to train a model via NAM.
- LV2 - LV2 is an extensible open standard for audio plugins. LV2 has a simple core interface, which is accompanied by extensions that add more advanced functionality.
- LV2 projects - This page is a partial list of LV2 projects. If you know of any that are not listed here, please let us know or send a patch.
- Ratatouille - Ratatouille is a Neural Model loader and mixer for Linux/Windows. It can load two models, which can be *.nam files with the Neural Amp Modeler module, or *.json or .aidax files with the RTNeural module.
What really look super interesting is the MOD Desktop tool. It is a webapp (that runs locally) that allows you to wire LV2 plugins together to create a custom guitar effects chain. Here’s a recent screentho and the link to the MOD Desktop in Github.
