Omni2Sound Evaluation Results

CVPR 2026 (Highlight)

Overview

This repository contains the evaluation results of Omni2Sound on three sub-tasks:

VT2A (Video + Text → Audio)
V2A (Video → Audio)
T2A (Text → Audio)

All results are evaluated on the VGGSound-Omni benchmark and stored as JSON files for reproducibility.

Evaluation Setup

Benchmark: Dalision/Omni2Sound_Benchmark (VGGSound-Omni)

Evaluation Toolkit: AV-Benchmark — the standardized evaluation toolkit from MMAudio, applied on 8-second clips following prior work.

Metrics cover four dimensions:

Dimension	Metrics
Distribution Matching	FAD, FD, FD_PaSST, KL, KL_PaSST
Audio Quality	IS, IS_PaSST, PQ (Production Quality)
Semantic Alignment	CLAP, MS-CLAP (text-audio), IB / ImageBind (video-audio)
Temporal Alignment	DS / Desynchronization Score (Synchformer)

All baseline models are re-evaluated using their official checkpoints with the same standardized toolkit and identical video/text conditions for fair comparison.
