Solid-Gold Flute Solo (432 Hz)
Recorded with the X-86S (Mini XLR version) using a flute made entirely of pure gold.
Due to production constraints it was tuned to 432 Hz—and as expected of a professional flutist, they performed at 432 Hz with excellent control.
Please listen for the accuracy of transient attack in the high register.

Nature & Field Recording
Hokkaido Snowfield (Dec 2025)
Recorded using only plug-in power with the P-86S.
Someone who grew up in snowy regions commented, “It’s unbelievably real.”
Tiny details of snow within the silence.
The sound changes dramatically depending on moisture content and temperature.
This is a recent recording that also served as an operation test in extreme cold at -18°C.

Onomichi, Hiroshima: Engine Sound of the Fukumoto Ferry
Nostalgic Onomichi.
As systems become increasingly electronic in recent years, oil-powered boats are becoming rare.
Recorded using my personal favorite recorder, the TASCAM DR-100MKIII, and plug-in power with the P-86S only.
An immersive presence that feels like you can even sense the smell of the place.

Reflections inside the gondola, and the mechanical drive noise.
The cabin environment is reproduced in full detail.
Doesn’t it feel like a scene from a movie?
