- JonnieCache 13y agoThere is plenty of real-time noise reduction software in VST plugin form. Here's an (expensive, but very effective) example: http://www.sonnoxplugins.com/pub/plugins/products/restore.htm http://www.sonnoxplugins.com/pub/plugins/products/restore.ht... Otherwise, you can get a long way with just traditional gating, EQing and maybe a multiband compressor.
- Joona 13y agoThanks, I should have mentioned that I don't know anything about audio, but I'll look in to it!
- JonnieCache 13y agoA gate only lets sound through when it goes above a certain level, so if you set the threshold just above the level of the noise, the parts of the audio that are just noise will be silenced. This obviously works best if you're treating something intermittent like speech or a single instrument, it wouldn't work on a whole piece of music. An EQ lets you attenuate certain frequencies, so if there are some parts of the spectrum in your recording which are just noise, you could remove them, eg. for speech you could remove all the information below 300hz and above 12-13000hz Multiband compression is a bit too complex to explain here :) The specialist plugins tend to use a combination of these techniques and then their own special secret algorithms, which is why they're so expensive.
- Joona 13y agoThanks for the explanation! I'm already using Noise Gate in OBS (livestreaming), but the noise is still an annoyance. I'll definitely look in to EQ. Thank you so much. :)
- JonnieCache 13y agoThe lowest hanging fruit for you will probably be improving the source. Get a better mic, make a pop shield out of an old pair of tights and a wire coathanger, fill the room with soft furnishings, make yourself a ghetto isolation booth by putting a duvet over your head and climbing into your wardrobe, etc. That last one might sound silly but many international-pop-career-launching albums have been recorded like that.
- Joona 13y agoI've been thinking about it, but I don't really want to use 100€ on a new mic. I'll try to "fix" this one first. :P Thanks for the advice!
