How Browser-Based Audio Processing Works
VidStudio uses FFmpeg compiled to WebAssembly to process audio entirely in your browser. When you upload a video or audio file, it stays on your device - nothing is sent to a server. The same professional-grade FFmpeg engine used by video studios worldwide runs locally, giving you format conversion, effects processing, and multi-track mixing without any installs or signups. Processing speed depends on your device, but most operations on typical files complete in seconds.
