# Neural Grey-Box Guitar Amplifier Modelling with Limited Data
This repository contains supplementary material for the DAFx23 paper [Neural Grey-Box Guitar Amplifier Modelling with Limited Data](https://www.dafx.de/paper-archive/2023/DAFx23_paper_52.pdf).

### Abstract
This paper combines recurrent neural networks (RNNs) with the discretised Kirchhoff nodal analysis (DK-method) to create a grey-box guitar amplifier model. Both the objective and subjective results suggest that the proposed model is able to outperform a baseline black-box RNN model in the task of modelling a guitar amplifier, including realistically recreating the behaviour of the amplifier equaliser circuit, whilst requiring significantly less training data. Furthermore, we adapt the linear part of the DK-method in a deep learning scenario to derive multiple state-space filters simultaneously. We frequency sample the filter transfer functions in parallel and perform frequency domain filtering to considerably reduce the required training times compared to recursive state-space filtering. This study shows that it is a powerful idea to separately model the linear and nonlinear parts of a guitar amplifier using supervised learning.

### Real-time version

The ```plugin``` directory contains the source code for the real-time version of the models presented in this work. The VST3 version compiled on Windows is located in the ```plugin/windows_build``` folder. The plugin enables switching between the proposed models (denoted as TS) trained on 4 and 12 minutes of data. The third model (RNN21) is a fully black-box conditioned LSTM model trained on 84 minutes of data.

#### Note that the plugin only works properly at a sampling rate of 44.1 kHz.
