I’ve been involved with acoustics for a long time and may have some expertise, can’t tell. But sure not heavy in the audiophile world.
Started with underwater things and branched into DSP.
Wrote a paper on modeling ocean reverberation.
Wrote a program to design half-band filters.
Wrote a program that designs all-pass reverberation-generating FIR filters.
In 2019 was privileged to attend a 4-day recording session at Abbey Road Studios with chorus backed by the London Royal Philharmonic Orchestra.
