 Unconditional audio generation using diffusion models, in PyTorch. The goal of this repository is to explore different architectures and diffusion models to generate audio (speech and music) directly from/to the waveform.
-Progress will be documented in the [experiments](#experiments) section.
+Progress will be documented in the [experiments](#experiments) section. You can use the [`audio-diffusion-pytorch-trainer`](https://github.com/archinetai/audio-diffusion-pytorch-trainer) to run your own experiments – please share your findings in the [discussions](https://github.com/archinetai/audio-diffusion-pytorch/discussions) page!
