What is 8Dfy?
8Dfy is a browser extension that wraps sound around your head. It takes any song, playlist, or video playing in YouTube, YouTube Music, or Apple Music and applies 8D rotation, multi-band surround, HRTF 3D positioning, or binaural beats so it feels like the audio is moving in space around you. It runs entirely in your browser — no audio data ever leaves your device.


The client-side Web Audio approach is the part that stands out. Keeping HRTF and 8D processing on-device means you can spatialize YouTube or Apple Music without shipping the stream anywhere, which is a rare privacy choice for this category. Curious how Auto DJ holds up on tracks without a clean kick—does beat detection fall back to a fixed crossfade when the transient is weak?

The privacy-first approach really sets this apart. Keeping all audio processing client-side via the Web Audio API removes a huge trust issue with most browser audio tools. The Auto DJ beat-matching is clever too - it turns playlist management into something that feels intentional rather than jarring.

The Auto DJ beat-matching and 8D rotation features are an interesting combination, especially the way the transitions are designed to preserve the flow between tracks. I’m curious how well the beat detection handles songs with less consistent rhythms or live recordings. The client-side processing is also a nice touch for privacy.
Really like that this runs entirely client-side via the Web Audio API, no audio ever leaves the device, which is a nice privacy angle most "enhance my music" extensions skip. Following up on Blogger sara's question about beat detection on less consistent rhythms: does the Auto DJ transition logic fall back to a simpler crossfade when it can't confidently lock onto a beat, or does it still force a hard cut? That edge case is what would make or break it for jazz or live recordings.
