I’ve looked through several posts here and have seen many good solutions and learned a lot. However I still need to post here because I could not help myself any further in an unfortunate situation:
I need to transcribe this recording (see spectrogram view) which has some horrible interference on a broad frequency spectrum most of the time. So if I listen closely it’s barely to impossible to recognize what’s said - for the full length of this recording it’s ugly to impossible work for me/my ears.
So I isolated unaffected frequency bands but can’t understand enough (too small unaffected bands). Is it possible to isolate multiple unaffected frequency bands?
I also tried noise reduction by identifying a noise profile (where noise only). This reduces the ugly interference significantly but I just could not find parameters and/or noise profiles such that enough of the spoken words remain. Maybe I’m simply too noobish. Do you have any advice?
