Summary

AudioX-Turbo is a unified and efficient framework for anything-to-audio generation, integrating diverse multimodal conditions like text, video, and audio signals. It employs a teacher-student paradigm, where the teacher, AudioX-Base, is a Multimodal Diffusion Transformer with a Multimodal Adaptive Fusion module designed for high-fidelity synthesis. This teacher model is then distilled into the few-step student, AudioX-Turbo, using Distribution Matching Distillation adapted to flow matching, enhanced by a diffusion-based discriminator for high-quality, few-step generation. To facilitate training, the framework utilizes IF-caps-Pro, a large-scale, high-quality dataset comprising approximately 9.2M samples. Benchmarking shows AudioX-Turbo achieves superior performance, particularly in text-to-audio and text-to-music generation, operating at only 4 sampling steps and requiring approximately 25x fewer function evaluations (NFE) than multi-step baselines.

Key takeaway

For Machine Learning Engineers developing multimodal audio generation systems, AudioX-Turbo offers a path to significantly reduce inference costs. You can achieve high-fidelity audio synthesis from text, video, or audio inputs with only 4 sampling steps, requiring 25x fewer function evaluations than traditional multi-step diffusion models. Consider adopting distillation techniques and large-scale curated datasets like IF-caps-Pro to enhance both efficiency and quality in your own models.
