This page includes of audio examples for the article Simionato R., Fasciani S., Comparative Study of Recurrent Neural Networks for Virtual Analog Audio Effects Modeling, submitted to EURASIP, 2024
Associated code, dataset, and trained models are available on GitHub.
Examples are available for the following datasets:
- OD300 Overdrive – Dataset – OD300 Overdrive Examples
- Neutron’s Overdrive – Dataset – Neutron’s Overdrive Examples
- Pultec Equalizer – Dataset – Pultec Equalizer Examples
- Neutron Low Pass Filter – Dataset – Neutron’s Filter Examples
- Helper Saturator – Dataset – Helper Saturator Examples
- BBD Saturation – Dataset – BBD Saturation Examples
- CL 1B – Dataset – CL1B Compressor Model Examples
- LA-2A – Dataset – LA-2A Compressor Model Examples
Each example includes the following:
- Input Audio Signal
- Target Output Audio Signal (true output recorded from the device)
- Predicted Output Audio Signal (generated by the inference of the trained model) for each recurrent model
- Spectrograms of Target and Predicted Output Audio Signals
The examples refer to four recurrent model, whose architectures are explained in the paper:
- LSTM
- LSTM-ED
- LRU
- S4D
The title of the waveform plot details the control parameters, that ranges between 0 (min) and 1 (max).
