Rebuilding My Piezo Signal Path for Accurate Acoustic Analysis
After tracing brittle transients and missing bass to piezo impedance mismatch, I researched buffering solutions and mapped my signal path. This field note documents the investigation, measurements, and hardware choices behind pursuing accurate steel tongue drum analysis—before the new preamp even arrives. Read More

Hopwell Steel Tongue Drum (15 note, Key of D)
A deep dive into a 15-note D-major steel tongue drum used as a rain-activated idiophone. Measured tuning accuracy, harmonic behavior, sustain, lacquer acoustics, and psychoacoustics reveal a thoughtfully engineered instrument that bridges ambient sound sculpture, melodic percussion, and experimental recording.
