Audio ControlNet for Fine-Grained Audio Generation and Editing
This paper introduces Audio ControlNet, a framework for fine-grained text-to-audio (T2A) generation and editing. It augments pre-trained T2A models with lightweight control networks (T2A-ControlNet and T2A-Adapter) to enable precise control over loudness, pitch, and sound events without retraining the backbone. T2A-Adapter achieves strong performance with fewer parameters. The framework is extended to T2A-Editor for temporally localized audio event insertion and removal. The results demonstrate precise, extensible control and editing capabilities for T2A models.

Precise Loudness Control
The T2A-Adapter achieved an MAE of 1.40 for loudness, outperforming EzAudio-L-Energy (MAE 2.22), showcasing its ability to enforce precise signal-level attributes.
Conclusion: This highlights the effectiveness of using Savitzky-Golay filtering and broadcasting for stable loudness control.
Introduction of T2A-Editor for localized audio event insertion and removal.

FlexSED Score for Insertion (T2A-Editor w/ LoRA)
Temporally Localized Editing
T2A-Editor, especially with LoRA, achieved a FlexSED score of 0.1340 for insertion and 0.0429 for removal, significantly improving over input audio's 0.0257 (removal), demonstrating its capability for precise temporal manipulation.
Conclusion: This enables fine-grained modification of audio content, crucial for professional sound design and post-production.
