- A link to Jacques Mattheij’s blog post “MP3 to MIDI” (https://jacquesmattheij.com/mp3-to-midi/) was shared, discussing techniques for converting audio recordings into symbolic musical data.  
- Deezer’s open-source “Spleeter” library for AI-based music source separation was highlighted; it provides pre-trained models that can isolate vocals and instruments from mixed tracks.  
- Because the official Deezer model-hosting site (github.deezerdev.com) was unreachable, a participant uploaded the 2-stem pre-trained model to archive.org (https://archive.org/details/model.data-00000-of-00001) to keep the resource publicly available.  
- Discussion turned to speculative physics: while a claimed “catalyst metamaterial” that boosts solar-cell efficiency by tapping neutrinos or dark matter was judged likely a scam, it was noted that genuine breakthrough interaction with dark-sector particles would constitute Nobel-level physics and yield effectively free energy, not marginal solar improvements.
