Description

looks like this was proposed (https://github.com/libretro/RetroArch/pull/15173#issuecomment-1504885797) before as a smooth audio fast forwarded output solution but seemingly only the resampling bit of this was ever merged

TIME STRETCH REF (duckstation): https://github.com/stenzek/duckstation/commit/68b5dd869c31e6f78aa2d17d90958737b60b115a

Research direction

Start by reviewing the earlier proposal in PR #15173 and the DuckStation time-stretch reference commit linked in the issue. Trace which resampling work was merged and identify the remaining audio fast-forward path. Done means fast-forwarded audio avoids pitch bending, but the issue does not name files or tests to use.
