AudioSRT is a browser-native audio transcription and subtitle generation platform powered by OpenAI Whisper AI models executed via asynchronous Web Workers and WebGPU memory-chunking pipelines. Unlike server-dependent transcription APIs, all media processing occurs entirely on the client device — eliminating upload latency, enforcing zero-knowledge privacy guarantees, and enabling unlimited file duration processing without queue throttling. The platform generates frame-accurate, millisecond-precision SRT subtitle files, plain-text transcripts, VTT caption files, and native Adobe Premiere Pro JSON session files compatible with Premiere's Text-Based Editing workflow. Exported subtitle sequences are fully compatible with Adobe Premiere Pro, DaVinci Resolve, Final Cut Pro X, CapCut, and all SMPTE-compliant NLE systems. The Web Worker architecture completely separates the Whisper inference thread from the browser's primary UI rendering thread, guaranteeing zero UI freezes or tab crashes during multi-hour media file processing.
