I would like to ask for help please. I don’t have an experience in sounds or recording or filtering. I have a voice record of two speaking with lots of background noise due to an instrument that was in the same room and due to a big freezer. I can’t hear the voices clearly. Anyone who have experience here who can help or can do a filtering for the voices ? It is just 6 minutes record. I don’t know how to do it or how much technology needed for it.

Thanks so much

Use a Limiter, "Filtering" in Particular is mostly connected to a EQ, which wont realy help you here (except u literally now which frequencies are hussling).

These are the Problems/ Thougts.

Voice Loud, Little Background Noise (Maybe a Chair or a Fan) : Use a Limiter, Its Threshold has to be around the middle of the Loudness of your Voice. So that there wont be ANY clipping of your Voice, basicly search for the spot where "only" the noise is in the treshhold. Gain to 0 basicly everything under the treshhold (u just set it to only noise) is muted i would set the Release to about 20-50 (so you have a bit of a fade and no hard clips)

Voices Loud, Realy Loud Noise : This will be the Problem. If your Noise is in the same Audiotrack as the Voice (which i presume) and the noise is as loud (50%/60% is a huge thing) you will have to use a EQ. Filter / Search for the frequencies where the voice is loud/present will be mostly in the mids/ highs (lowend mostly will be noise) and cut them out. If u have access to a strong MultibandCompressor as the FabFilter Pro-MB or an Dynamic EQ as FabFilter Pro-Q3 or TDR Nova. U could scan for where x frequencies are noisy and turn them down except for when it exceeds a certain treshhold (maybe voice) and turn it up.

TL:DR If u have a simple bad microphone and there is some noise (tolerable noise) inside the audio file. Try a Limiter an set the Threshhold to the low noise.

If u have extreme loud noise (in which case if u wanna use it re-record it, i take this here as a "safe the audio" case) try to filter it out. This scenario will only be interesting if its maybe some unrecreateable audio (oldschool samples/ etc.) to save it. If u have a bad audio and are able to fix stuff with recording, do it.

last quick tip. If u wanna do music with it, most of the time after basic processing (EQ/DS/MB) there wont be any noticable noise. some reeverbs could just make it unhearable or even get some ambiente going.

I hope i could help you ! come again for questions

  • The Particular "Limiter" can be found if u google "noise-gate", most limiters have it already build in (dfntly the audacity and fl studio one) just google "noise gate [LIMITEROFYOURCHOISE]" Mar 10 at 12:23
