[NVIDIA](https://savrn.com/model-publishers/nvidia)

For the commercially friendly model, please refer to NVIDIA-NemotronLabs-RE-USE and NVIDIA-NemotronLabs-RE-USE-laughter In universal speech enhancement, the goal is to restore the quality of diverse degraded speech while preserving fidelity, ensuring that all other factors remain unchanged, e.g., linguistic content, speaker identity, emotion, accent, and other paralinguistic attributes. Inspired by the distortion–perception trade-off theory, our proposed single model achieves a good balance between these two objectives and has the following desirable properties: - Robustness to diverse degradations, including additive noise, reverberation, clipping, bandwidth limitation, codec artifacts…

Model for the music source separation task, decomposes audio into four stems: bass, drums, other, and vocals. 针对音乐音频分离的 BS-RoFormer 模型，将音频分离为 bass、drums、other、vocals。 在 MUSDB18HQ 数据的 val 集上的性能（单位 SDR，越高越好）： 使用的 transformers 库版本为 5.18.0，PyTorch 版本为 2.14.1。为了正常运行模型还需要安装库 soundfile、einops 和 librosa。 GPU 推理： 以上代码会分离出 bass、drums、other 和 vocal 四个轨道。 Mini-BS-RoFormer-V2.5 相比于 V2 的主要改进： 2. 利用注意力池化达成各 stem 共享 mask 解码器 3. 去掉 MUSDB18HQ 数据集中的坏数据进行训练 使用 MUSDB18HQ 数据集的 train 和 test 集进行训练。 学习率 3e-4，以 batchsize=8 训练 246k 步。 对 transformer 层使用 Muon 优化器，其他网络层使用 AdamW 优化器。 - https://github.com/lucidrains/BS-RoFormer - https://arxiv.org/abs/2309.02612 (Music Source Separation with Band-Split RoPE Transformer)

Voice conversion for Asante Twi (twi). An audio-to-audio model that converts speech into the Zephyr voice while preserving the language. This checkpoint is dedicated to Asante Twi: it was fine-tuned only on Asante Twi (twi) clips from starting from the zero-shot seed-uvit-whisper-small-wavenet base. Use it to convert audio in Asante Twi. For other languages — or as a cross-lingual fallback — use ghanaopenai/ghana-vc. The library auto-selects this model when the dataset/config name matches.

A small causal Qwen3 model that predicts 32 MOSS v2 audio-codebook indices from the 12 indices of the current frame and up to ten previously generated HQ frames. It is trained from scratch on German, English, Spanish and French speech. This is an experimental enhancement model. Validation cross entropy measures token prediction under teacher forcing. It does not establish an improvement in perceived audio quality. Use the generated-history listening evaluation to judge speech content, speaker identity, artifacts and long-utterance stability. Root inference weights: step 64,699, selected by held-out extra-20-codebook cross entropy 5.818123. - Step 12,940: 100 originals / 200 input cases…
