Well, ok, here goes - some sharing as well as a question. I've been recording some solo instrumental minimalism. I know it's a bit odd, it's very soundscape, so if you're into composers like Steve Reich (one of the tracks is a very specific take on his style) or Philip Glass, you might appreciate this. If not, no worries, move on. Monophone - Instrumental minimalism from Seoul, Korea And the question - I'm recording direct out from a small Hartke combo into a Korg D4 digital 4-track, and then using Audacity to level the tracks and export them into FLAC to upload onto Bandcamp. There's lots of noise, but most of it is intentional, as I really am trying to go for a rough, irregular sound as well as structure - I love the chattery 60-cycle hum, and brittle static of the single coils (it's a Guild JS-II with Hagstroms, the one in my avatar), but there's one thing I can't get rid of: when there's a very bass-y signal (I use a Boss PQ-3B for the low end, and an Arion Parameric EQ for the dry high treble), there's this 'microphonic' whistle almost - only when it's a very bass-only kind of signal, pure low frequency. It's not at all present in the performance but emerges in the recording ONLY. I think it's the Korg, because when I listen to the playback on the D4 that's when I start to hear it. Any advice on removing that microphonic signal in Audacity, or better yet, preventing it from ever being on the recording? Even in videos online, even Ed Friedland's videos, you'll hear these microphonics I'm talking about when there's a real low-end signal. Anyway, enjoy!
