# Bidirectional sound transport

## One-sentence takeaway

Bidirectional sound transport JASA 2017: journal write-up of acoustic BDPT (Cao/Ren/Schissler/Manocha/Zhou) — same team as SIGGRAPH Asia 2016.

## Why it matters here

Harvest ranked both 2016 TOG and 2017 JASA. Keep as the acoustics-journal sibling (ASA audience) without reminting the algorithm. Cite 1690 for the graphics paper, this for JASA DOI 10.1121/1.4987162.

## Key ideas

- **Acoustic BDPT.** Source and listener subpaths.
- **JASA 2017.** Harvest path-traced/MC; cite count 1 in harvest (abstract-ish?).
- **Same authors as 2016 TOG.**
- **Geometric MC auralization.**

## Caveats

Likely overlapping contribution with 1690 — kept because harvest listed both as keepers. Prefer 2016 for figures/system. Not differentiable 2025.
