The following audio samples are provided as supplementary material for our paper Adversarial Guitar Amplifier Modelling.
All models operate in an unpaired data scenario, where aligned pairs of input and target waveforms are not available.
GAN-based models all share the same time-domain convolutional Generator achitecture, but use various Discriminator architectures.
Target is an Ibanez 2820 guitar played through various guitar amplifier settings.
Plugin only (oracle) is a Career SG guitar played through the ground truth amplifier model.
The amplifier sound is correct, but mismatching guitars contribute to a mismatch in timbre.
EQ + Plugin (oracle) applies a linear matching EQ to the Career SG samples before passing them through the ground truth amp model.
In addition to the ground truth amp, this approach requires some knowledge of the reference guitar, which is generally not available.
Mel Critic (proposed) uses a multi-resolution mel-spectral discriminator
Spec Critic (proposed) uses a multi-resolution linearly spaced spectral discriminator.
