I’d love to try that! A simple way is to use a handheld recorder with a decent mic, like an AKG or a small shotgun mic, and set it to a high‑bit depth, maybe 24‑bit at 96kHz, so you catch all the little whispers. Put the mic on a boom pole or a stand about a meter off the ground and aim it at the trees so the wind and leaves are front and centre. In my garden I’d set up a little station next to a rock by the old oak. Bring a small solar‑powered charger, a tiny speaker for playback, and a notebook to jot down the times of day when the wind is calm or the birds are singing. Stick a windscreen on the mic, tape a soft material to reduce wind noise, and you’ll get a clean, natural sound. Try recording at dawn and dusk when the light is gentle; those times also bring the best bird calls. Remember to keep the mic away from any vibrations on the ground, maybe put a cushion or a rubber mat underneath. That way you’ll capture the soft murmur of the brook and the rustle of leaves in all their subtlety.
