+# Musika Techno Model
+
+Pretrained Techno GAN model for the [Musika system](https://github.com/marcoppasini/musika) for fast infinite waveform music generation.
+Introduced in [this paper](https://arxiv.org/abs/2208.08706).
+
+## Model description
+
+This pretrained GAN system consists of a ResNet-style generator and discriminator. During training, stability is controlled by adapting the strength of gradient penalty regularization on-the-fly. The gradient penalty weighting term is contained in *switch.npy*. The generator is conditioned on a latent coordinate system to produce samples of arbitrary length. The latent representations produced by the generator are then passed to a decoder which converts them into waveform audio.
+The generator has a context window of about 12 seconds of audio.
+
+### How to use
+
+This pretrained Techno GAN system is automatically downloaded at the first execution of the system. Try Musika [here](https://github.com/marcoppasini/musika)!
+
+
+## Training data
+
+The Techno GAN system was trained on 1000 hours of music with the *techno* tag from *jamendo.com*.
