The NeMo NanoCodec is a neural audio codec that leverages finite scalar quantization and adversarial training with large speech language models to achieve state-of-the-art audio compression across different bitrate and frame rate ranges.
Model variant details:
| Sample Rate | Frame Rate | Bit Rate | # Codebooks | Codebook Size | Embed Dim | FSQ Levels |
|:-----------:|:----------:|:----------:|:-----------:|:-------------:|:-----------:|:------------:|
| 22050 | 21.5 | 1.89kpbs | 8 | 2016 | 32 | [8, 7, 6, 6] |
This model is ready for commercial/non-commercial use.
