Add pipeline_tag and paper link

This PR updates the model card by adding the `pipeline_tag: text-to-audio` to the metadata, which is crucial for categorizing the model correctly. It also includes the paper title and a direct link to the paper at the beginning of the content for better visibility.

 # EzAudio: Enhancing Text-to-Audio Generation with Efficient Diffusion Transformer
 
+[EzAudio: Enhancing Text-to-Audio Generation with Efficient Diffusion Transformer](https://huggingface.co/papers/2409.10819)
+
+**Abstract:** We introduce EzAudio, a text-to-audio (T2A) generation framework designed to produce high-quality, natural-sounding sound effects. Core designs include: (1) We propose EzAudio-DiT, an optimized Diffusion Transformer (DiT) designed for audio latent representations, improving convergence speed, as well as parameter and memory efficiency. (2) We apply a classifier-free guidance (CFG) rescaling technique to mitigate fidelity loss at higher CFG scores and enhancing prompt adherence without compromising audio quality. (3) We propose a synthetic caption generation strategy leveraging recent advances in audio understanding and LLMs to enhance T2A pretraining. We show that EzAudio, with its computationally efficient architecture and fast convergence, is a competitive open-source model that excels in both objective and subjective evaluations by delivering highly realistic listening experiences. Code, data, and pre-trained models are released at: this https URL .

 ## Usage
 
 You can use the model with the following code:
 
 ```python
-from api.ezaudio import load_models, generate_audio
-
-# model and config paths
-config_name = 'ckpts/ezaudio-xl.yml'
-ckpt_path = 'ckpts/s3/ezaudio_s3_xl.pt'
-vae_path = 'ckpts/vae/1m.pt'
-# save_path = 'output/'
-device = 'cuda' if torch.cuda.is_available() else 'cpu'
+from api.ezaudio import EzAudio
+import torch
+import soundfile as sf
 
 # load model
-(autoencoder, unet, tokenizer,
- text_encoder, noise_scheduler, params) = load_models(config_name, ckpt_path,
-                                                      vae_path, device)
+device = 'cuda' if torch.cuda.is_available() else 'cpu'
+ezaudio = EzAudio(model_name='s3_xl', device=device)
 
+# text to audio genertation
 prompt = "a dog barking in the distance"
-sr, audio = generate_audio(prompt, autoencoder, unet, tokenizer, text_encoder, noise_scheduler, params, device)
+sr, audio = ezaudio.generate_audio(prompt)
+sf.write(f'{prompt}.wav', audio, sr)
+
+# audio inpainting
+prompt = "A train passes by, blowing its horns"
+original_audio = 'ref.wav'
+sr, audio = ezaudio.editing_audio(prompt, boundary=2, gt_file=original_audio,
+                                  mask_start=1, mask_length=5)
+sf.write(f'{prompt}_edit.wav', audio, sr)
+```
+
+## Training
+
+#### Autoencoder
+Refer to the VAE training section in our work [SoloAudio](https://github.com/WangHelin1997/SoloAudio)
+
+#### T2A Diffusion Model
+Prepare your data (see example in `src/dataset/meta_example.csv`), then run:
 
+```bash
+cd src
+accelerate launch train.py
 ```
