Researchers have developed a method to improve the computational efficiency of diffusion-based text-to-audio models like AudioLDM 2. By applying a filter-pruning strategy to the U-Net backbone, they were able to reduce parameters by up to 83% and multiply-accumulate operations by 39%. While this pruning initially affected the generation of specific sounds such as gunshots, sirens, and mechanical noises, a lightweight fine-tuning process largely recovered these capabilities, sometimes even improving overall generation quality.
