Bluetooth noise interference

Description

Trying out a omni-microphone, the Superlux ECM999. And recording a few serious things along the way. Recorded 2025 02 13. On a Tascam FR-AV2, and a single Superlux ECM 999 measurement microphone. I think it's fairly noisy, and sensitive to phone / Bluetooth frequencies. If I had more time, id write a better description ;_;
