xcodec2-25TPS-24k

This repository contains the improved X-Codec-2.0 model as described in the paper Improving X-Codec-2.0 for Multi-Lingual Speech: 25 Hz Latent Rate and 24 kHz Sampling.

Improve https://huggingface.co/HKUSTAudio/xcodec2 from 50 TPS to become 25 TPS and upscale output to 24k sample rate.

WanDB at https://wandb.ai/huseinzol05/xcodec2-24k-25tps, we also pushed all checkpoints in checkpoint.

How to use

1. Git clone,

git clone https://github.com/Scicom-AI-Enterprise-Organization/X-Codec-2.0-25TPS-24k
cd X-Codec-2.0-25TPS-24k

2. Load the model,

from modeling_xcodec2 import XCodec2Model
model = XCodec2Model.from_pretrained("Scicom-intl/xcodec2-25TPS-24k")

3. Encode,

import librosa
import torch

y, sr = librosa.load('259041.mp3', sr = 16000)
wav_tensor = torch.from_numpy(y).float().unsqueeze(0)
codes = model.encode_code(wav_tensor)

4. Decode,

import IPython.display as ipd

ipd.Audio(model.decode_code(codes)[0, 0].cpu(), rate = 24000)
