Diffusers format for Meituan's LongCat-AudioDiT-1B.

Model Description

A DiT (Diffusion Transformer) based audio generation model for text-to-audio synthesis.

Usage

python

import soundfile as sf
from diffusers import LongCatAudioDiTPipeline
import torch

pipeline = LongCatAudioDiTPipeline.from_pretrained(
    "ruixiangma/LongCat-AudioDiT-1B-Diffusers",
    torch_dtype=torch.bfloat16
)

pipeline = pipeline.to("cuda")

prompt = "A calm ocean wave ambience with soft wind in the background."
audio = pipeline(prompt, audio_duration_s=5.0, num_inference_steps=20, guidance_scale=4.0, seed=42).audios[0, 0]

sf.write("output.wav", audio, pipeline.sample_rate)
