jak-project's 989snd (ISC)
host/src/rac1/snd989.c and host/src/rac1/snd989_tables.h (the host's
989snd IOP driver) follow the jak-project's reimplementation of 989snd
(https://github.com/open-goal/jak-project, game/sound/989snd and
game/sound/common, by Ziemas) for the sound-effect grain semantics, the LFOs,
the volume and pan rules (MakeVolume, AdjustVolToGroup), the note-to-pitch
conversion, and they take from it the note pitch table, the pan table and the
SPU's Gaussian interpolation table. Those files are under the ISC licence:

The SPU2 reverb in the same file is written from the hardware's formula as documented in nocash's psx-spx; its preset register values are the PlayStation sound library's effect modes.
