# WideCodec — 44.1 kHz decoder (scaled NeuCodec depth-20 finetune)

**A SOTA 0.8 kbps, 44.1 kHz audio tokenizer.**

**WideCodec** is a **44.1 kHz decoder finetune** of [`neuphonic/neucodec`](https://huggingface.co/neuphonic/neucodec).
Only the **decoder** (Vocos backbone + ISTFT head, transformer **depth 20**) is trained to
reconstruct **44.1 kHz** audio. The **16 kHz acoustic/semantic encoders and the ResidualFSQ
codebook are frozen and completely unchanged** — the discrete codes are identical to base
NeuCodec, so this model is a drop-in higher-fidelity decoder.

- **Sample rate:** 44 100 Hz · **hop:** 882 · **50 tokens/sec**
- **Trainable:** decoder only (GAN: multi-period + spec discriminators; losses: multi-res mel + STFT + feature-matching + adversarial)
- **Frozen:** w2v-BERT semantic encoder, acoustic `CodecEnc`, `fc_prior`/`fc_post_a`, FSQ codebook

## Inference (self-contained)

Everything needed to run inference is **in this repo** — the `neucodec/` package and
`infer_widecodec.py`. No other source code required.

```bash
pip install torch transformers huggingface_hub local-attention einops librosa soundfile
huggingface-cli login          # if this repo is private (or export HF_TOKEN=hf_...)

huggingface-cli download Scicom-intl/WideCodec --local-dir WideCodec
cd WideCodec
python infer_widecodec.py --input my.wav --out-dir out      # one file
python infer_widecodec.py --input folder/  --out-dir out    # a directory
```

Or load it directly in Python:

```python
import sys; sys.path.insert(0, "WideCodec")   # the downloaded repo dir
import torch, librosa
from neucodec import NeuCodec

model = NeuCodec._from_pretrained(model_id="Scicom-intl/WideCodec", decoder_depth=20).eval().cuda()
wav16, _ = librosa.load("my.wav", sr=16000, mono=True)   # encoder ingests 16 kHz mono
x = torch.from_numpy(wav16).float().view(1, 1, -1).cuda()
with torch.no_grad():
    codes  = model.encode_code(x)      # frozen FSQ codes — 0.8 kbps, 50 tok/s
    wav44  = model.decode_code(codes)  # 44.1 kHz reconstruction
```

## How WideCodec compares (44 kHz-class, by bitrate)

Offline benchmark on a **heavily multilingual 9,291-clip wideband set** (50 clips × 188 clean ≥44.1 kHz datasets, **400+ language/dialect tags**),
faster-UTMOSv2 + spectral vs ground truth. **Read this by bitrate, not raw MOS** — these
codecs span a ~30× bitrate range. DAC/NeMo/EnCodec are high-bitrate multi-codebook RVQ
*acoustic* codecs; WideCodec is a **single-codebook, 50-tokens/s** code at **~0.8 kbps** —
the only one here whose token stream an autoregressive LLM/TTS model can practically predict.

![bitrate vs UTMOSv2](bitrate_vs_utmosv2.png)

| codec | native SR | tokens/s | codebooks | ~bitrate | UTMOSv2 | mel-L1 ↓ | HF≥11k | rolloff |
|---|--:|--:|--:|--:|--:|--:|--:|--:|
| ground truth | — | — | — | — | 2.822 | — | 0.00244 | 8263 |
| nvidia nemo44k | 44.1k | ~86 | RVQ (many) | ~6–9 kbps | **2.903** | 0.379 | 0.00196 | 8372 |
| **WideCodec (ours, gs-2.0M)** | 44.1k | **50** | **1** | **~0.8 kbps** | **2.788** | 0.571 | 0.00223 | 9011 |
| dac | 44.1k | 86 | 9 | ~8 kbps | 2.672 | **0.341** | 0.00156 | 8185 |
| snac44k | 44.1k | multi-scale | 3–4 | ~2.6 kbps | 2.340 | 0.493 | 0.00158 | 8402 |
| encodec48k | 48k | 150 | RVQ | 24 kbps | 2.042 | 0.458 | 0.00169 | 8800 |

**Bitrate = frame-rate × Σ log₂(codebook size).** WideCodec's FSQ is `levels=[4]×8,
num_quantizers=1` → 8·log₂4 = **16 bits/frame** × 50 frames/s = **800 bps = 0.8 kbps**
(vs DAC's 9 codebooks × 10 bits × 86 fps ≈ 8 kbps).

The **WideCodec row is the final gs-2.0M checkpoint** (9,291-clip set). At ~0.8 kbps / 1 codebook it **beats DAC on naturalness** (UTMOSv2 2.79 vs 2.67) using ~10x fewer bits, and lands within ~0.12 of NeMo's ~6-9 kbps RVQ. It carries genuine high-band content (rolloff 9.0 kHz; HF energy ~91% of ground truth), and genuine high-band content (reference-based LSD-HF 0.96, on par with the 8-kbps RVQ codecs), trading in-band fidelity for a ~10x bitrate advantage. (PESQ/SI-SDR are excluded — they structurally penalize a low-bitrate generative decoder regardless of naturalness.) Full report:
evaluation/REPORT_44k_class_codecs.md.

## Training stages / which revision to pull

This model is trained in two stages. `main` always points at the **latest** stage.

| stage | data | how to load |
|---|---|---|
| **Stage 1 — noisy mix** (steps 0→1.58M, `epoch=9-step=1580000`) | 8 base corpora + `scale44k` (~6,500 h, mostly noisy crowdsourced/podcast) | pin revision **`d2c612f4319c1c1e0c65a9431a7d6db1b7955ce0`** |
| **Stage 2 — clean finetune** (from 1.58M, clean ≥44.1 kHz only; in progress) | TTS-Clean44k + Clean-Podcast + clean-teacher pool + EARS/Expresso | `main` (default) |

```python
# the `neucodec/` package is bundled in this repo (see 'Inference (self-contained)')
from neucodec import NeuCodec

# Stage 1 (first-stage noisy training) — pin the exact revision:
model = NeuCodec._from_pretrained(
    model_id="Scicom-intl/WideCodec",
    decoder_depth=20,
    revision="d2c612f4319c1c1e0c65a9431a7d6db1b7955ce0",
)
```

## Training data

Diverse, predominantly high-sample-rate human speech (no synthetic TTS). The **scale-up group is
SR-verified ≥ 44 kHz** (probed before inclusion); the base corpora are long-form conversational,
expressive and anechoic speech. Two groups:

### Base corpora (Malaysia-AI + expressive/anechoic speech)

| dataset | content |
|---|---|
| [`malaysia-ai/malaysian-podcast-youtube`](https://huggingface.co/datasets/malaysia-ai/malaysian-podcast-youtube) | Malay long-form conversational podcasts (~2,234 h) |
| [`malaysia-ai/singaporean-podcast-youtube`](https://huggingface.co/datasets/malaysia-ai/singaporean-podcast-youtube) | Singaporean English podcasts (~1,255 h) |
| [`malaysia-ai/Multilingual-TTS`](https://huggingface.co/datasets/malaysia-ai/Multilingual-TTS) | CommonVoice-sidon multilingual short clips |
| [`malaysia-ai/malaysian-cartoons-youtube`](https://huggingface.co/datasets/malaysia-ai/malaysian-cartoons-youtube) | 48 kHz cartoon dialogue (subset) |
| [`malaysia-ai/malaysian-movie-youtube`](https://huggingface.co/datasets/malaysia-ai/malaysian-movie-youtube) | 48 kHz Malay movie dialogue |
| [`ylacombe/expresso`](https://huggingface.co/datasets/ylacombe/expresso) | 48 kHz expressive read speech |
| [`nytopop/expresso-conversational`](https://huggingface.co/datasets/nytopop/expresso-conversational) | 48 kHz improvised dialogue |
| EARS | 48 kHz anechoic fullband (emotional / conversational / reading) |

### Scale-up: 336 verified ≥ 44 kHz datasets

To maximise acoustic diversity for the decoder (language-agnostic — the codebook is frozen),
training is scaled with **336 additional datasets** (162 at 48 kHz, 174 at 44.1 kHz), mirrored as
`<name>*audio.zip` in [`malaysia-ai/Multilingual-TTS`](https://huggingface.co/datasets/malaysia-ai/Multilingual-TTS)
and SR-verified ≥ 44 kHz. Original sources:

## Usage

See the canonical
**Load from Hugging Face**
section in the source repo. **`decoder_depth=20` is required** — the weights are a
depth-20 decoder, so loading with any other depth mismatches the architecture.

```python
import soundfile as sf

# the `neucodec/` package is bundled in this repo (see 'Inference (self-contained)')
from neucodec import NeuCodec

# decoder_depth=20 MUST match this repo; pass token=... (or hf login) for access
model = NeuCodec._from_pretrained(model_id="Scicom-intl/WideCodec", decoder_depth=20)
model = model.eval().cuda()

# encode (16 kHz path, frozen) -> codes -> decode (44.1 kHz, this finetune)
codes = model.encode_code("input.wav")                   # [1, 1, T], identical to base NeuCodec
recon_44k = model.decode_code(codes).squeeze().cpu().numpy()
sf.write("recon.wav", recon_44k, model.sample_rate)      # 44100
```

The discrete codes are **identical to base `neuphonic/neucodec`** — only the reconstruction
sample rate and fidelity differ.
