Each QR code points to the current time in the audio. The idea is: if you upload the audio as a video to YouTube, anyone can pause, scan the on-screen QR code, and jump straight to that exact moment.

Use case: podcasts, lectures, music jam sessions, or any long-form audio where you want to bookmark/share precise moments without scrubbing.

How it works: - Generates QR codes like https://tinyurl.com/arp20130725?t=565 - Muxes them with the audio into an MP4 using ffmpeg - Optionally writes a `.srt` file with matching timestamps - You set up the short URL (e.g., with TinyURL) to redirect to your YouTube upload

Much of the code was generated with AI and adjusted for my needs.
