Re: Dehumming clavinet recording

Hello David and all,
thanks first for that tip. It has decreased the problem slightly.

Seeing is knowing, here is a short example:
https://www.dropbox.com/scl/fi/4clxqzetettjgbch8dja0/noise.flac?rlkey=t9e8x4ls4nfpya459wzd15h42
This is raw, just converted to 44.1kHz 16bit.

Best wishes,

Jeanette
