I built Aurora Subtitles, a Windows application that generates real-time subtitles and translation from microphone or system audio.
Everything runs locally using Whisper for transcription and NLLB for translation. CUDA acceleration is supported to reduce latency, and subtitles appear as an overlay on screen.
The goal was to create something useful for: - voice chats and Discord - games - meetings - accessibility, including helping people with hearing impairments
No cloud APIs are required and everything runs locally.
Feedback is very welcome.
