Deep Analysis

Background

Multimodality-to-multiaudio generation aims to produce various audio types from multimodal inputs like video, text, and images. Recent advances in text-to-audio and video-to-audio generation have been significant, but the lack of large-scale paired datasets limits the development of a unified framework.

Core Problem

Multimodality-to-multiaudio generation faces three main challenges: inadequate fine-grained understanding of multimodal inputs, inability of single models to handle diverse audio events, and absence of self-correction mechanisms for reliable outputs.

Innovation

AudioGenie addresses these challenges with a training-free multi-agent system. The generation team uses task decomposition and adaptive expert model selection, while the supervisor team ensures output consistency through feedback loops.

Methodology

  • �� The generation team decomposes complex audio requirements into manageable sub-events.
  • �� Adaptive expert model selection chooses suitable generation models.
  • �� Trial-and-error iterative refinement module uses feedback loops for self-correction and output optimization.

Experiments

Experiments use the MA-Bench benchmark, comprising 198 annotated videos with multi-type audios. AudioGenie is evaluated across 9 metrics in 8 tasks, with user studies validating its effectiveness in quality, accuracy, alignment, and aesthetics.

Abstract

Multimodality-to-Multiaudio (MM2MA) generation faces significant challenges in synthesizing diverse and contextually aligned audio types (e.g., sound effects, speech, music, and songs) from multimodal inputs (e.g., video, text, images), owing to the scarcity of high-quality paired datasets and the lack of robust multi-task learning frameworks. Recently, multi-agent system shows great potential in tackling the above issues. However, directly applying it to MM2MA task presents three critical challenges: (1) inadequate fine-grained understanding of multimodal inputs (especially for video), (2) the inability of single models to handle diverse audio events, and (3) the absence of self-correction mechanisms for reliable outputs. To this end, we propose AudioGenie, a novel training-free multi-agent system featuring a dual-layer architecture with a generation team and a supervisor team. For the generation team, a fine-grained task decomposition and an adaptive Mixture-of-Experts (MoE) collaborative entity are designed for detailed comprehensive multimodal understanding and dynamic model selection, and a trial-and-error iterative refinement module is designed for self-correction. The supervisor team ensures temporal-spatial consistency and verifies outputs through feedback loops. Moreover, we build MA-Bench, the first benchmark for MM2MA tasks, comprising 198 annotated videos with multi-type audios. Experiments demonstrate that our AudioGenie achieves state-of-the-art (SOTA) or comparable performance across 9 metrics in 8 tasks. User study further validates the effectiveness of our method in terms of quality, accuracy, alignment, and aesthetic.
