  Foley sound, audio content inserted synchronously with videos, plays a
critical role in the user experience of multimedia content. Recently, there has
been active research in Foley sound synthesis, leveraging the advancements in
deep generative models. However, such works mainly focus on replicating a
single sound class or a textual sound description, neglecting temporal
information, which is crucial in the practical applications of Foley sound. We
present T-Foley, a Temporal-event-guided waveform generation model for Foley
sound synthesis. T-Foley generates high-quality audio using two conditions: the
sound class and temporal event feature. For temporal conditioning, we devise a
temporal event feature and a novel conditioning technique named Block-FiLM.
T-Foley achieves superior performance in both objective and subjective
evaluation metrics and generates Foley sound well-synchronized with the
temporal events. Additionally, we showcase T-Foley's practical applications,
particularly in scenarios involving vocal mimicry for temporal event control.
We show the demo on our companion website.
