Sign up for Diffio

The first 60 seconds of an archival David Gooding lecture, used with the owner’s permission. The Flash and Pro versions were rendered on November 3, 2026 from the released Diffio 4.7 weights on Diffio’s own GPU, with the same processing as the app around the model, not through the public API. All three play at matched loudness as 160 kbps MP3, with no other enhancement. Source and render record.
