Silence Speedup is a desktop application built with Electron that analyzes videos or audio files to detect silent sections and either speed them up or remove them entirely. Powered by FFmpeg, it helps you reduce unnecessary pauses and make your content more concise.
Ideal for lectures, interviews, podcasts, or tutorials — especially when the speaker pauses frequently or speaks slowly.
Latest release: v2.0.0
- Launch the application
