| # Aliasing-Free Neural Audio Synthesis | |
| This is the official Hugging Face model repository for the paper **"[Aliasing-Free Neural Audio Synthesis](https://arxiv.org/abs/2512.20211)"**, which is the first work to achieve simple and efficient aliasing-free upsampling-based neural audio generation in the entire field of neural vocoders and codecs. | |

| ## Model Checkpoints | |
| This repository contains the following checkpoints: | |
| | Model Name | Directory | Description | | |
| | ----------------- | ---------------------------- | ------------------------------------------------- | | |
| | **Pupu-Vocoder_Small** | `./pupuvocoder/*` | 14M parameter small version of Pupu-Vocoder. | | |
| | **Pupu-Vocoder_Large** | `./pupuvocoder_large/*` | 122M parameter large version of Pupu-Vocoder. | | |
| | **Pupu-Codec_Small** | `./pupucodec/*` | 32M parameter small version of Pupu-Codec. | | |
| | **Pupu-Codec_Large** | `./pupucodec_large/*` | 119M parameter large version of Pupu-Codec. | | |
| ## How to use | |
| You need to put the pretrained models in: | |
| ```bash | |
| AliasingFreeNeuralAudioSynthesis/experiments | |
| ``` | |
| of our official repository, and then follow the instructions written in the [GitHub repository](https://github.com/sizigi/AliasingFreeNeuralAudioSynthesis) to resume, finetune, and inference our pretrained checkpoints. | |
