Keep the microphone at a distance (avoid contact recording): Placing the microphone directly against the wooden casing amplifies motor noise. It is recommended to use an external microphone and maintain an appropriate distance to fully capture the room’s natural reverberation.

Lightweight equipment and simple post-processing: Lavalier microphone: Position a small microphone (e.g., Boya Lav) in front of the sound hole, and apply noise reduction plugins (e.g., Brufsi) during post-processing to reduce mechanical noise.

Handheld recorder: Use a portable recorder (e.g., Zoom H2) for audio capture, then apply noise reduction software and EQ adjustments during post-processing to minimize motor noise. Musician Christophe’s test: https://www.youtube.com/watch?v=kGFHOOBNx6k
