  Audio-driven visual scene editing endeavors to manipulate the visual
background while leaving the foreground content unchanged, according to the
given audio signals. Unlike current efforts focusing primarily on image
editing, audio-driven video scene editing has not been extensively addressed.
In this paper, we introduce AudioScenic, an audio-driven framework designed for
video scene editing. AudioScenic integrates audio semantics into the visual
scene through a temporal-aware audio semantic injection process. As our focus
is on background editing, we further introduce a SceneMasker module, which
maintains the integrity of the foreground content during the editing process.
AudioScenic exploits the inherent properties of audio, namely, audio magnitude
and frequency, to guide the editing process, aiming to control the temporal
dynamics and enhance the temporal consistency. First, we present an audio
Magnitude Modulator module that adjusts the temporal dynamics of the scene in
response to changes in audio magnitude, enhancing the visual dynamics. Second,
the audio Frequency Fuser module is designed to ensure temporal consistency by
aligning the frequency of the audio with the dynamics of the video scenes, thus
improving the overall temporal coherence of the edited videos. These integrated
features enable AudioScenic to not only enhance visual diversity but also
maintain temporal consistency throughout the video. We present a new metric
named temporal score for more comprehensive validation of temporal consistency.
We demonstrate substantial advancements of AudioScenic over competing methods
on DAVIS and Audioset datasets.
