Your best bet is to prevent noise from occurring in the first place. Either way, most noise removal tools will listen to the noise and try to identify what they can remove.
If it is random background noise, then it may be fairly difficult to remove unless it is pretty regular frequencies. Basically, it depends on the kind of noise you are getting though. You may find this answer from our sister site Sound Design to be useful. Something like Adobe Audition, Apple Logic Pro, or Avid Pro Tools. Something paid and marketed as a DAW (digital audio workstation), would do the job much better. That said, it's still probably the best free program available. A parametric eq also requires an external plugin. UPDATE: Audacity does have a compressor, but the GUI looks really ugly and unintuitive. Generally you can coat a fairly large room at 50-75% coverage for under $100. This won't solve existing noise problems, but it will limit reverb. Another slightly cheaper idea is to give your recording room an acoustic treatment, essentially coating the walls in acoustic foam. In terms of the recording environment, ideally you could build a sound proof room, but these are incredibly expensive. This works particularly well if there's a hissing sound that fills up only a small area on the frequency spectrum. You can use this to raise the level of your voice, but also soften background noise. Essentially the equalizer loudens or softens sound based on its frequency. Look specifically for a parametric eq these are the most intuitive. This technique will not work if your voice is not considerably above the level of the background noise.Īnother tool which can help refine your voice, but not entirely solve the noise problem is an eq (equalizer). This will also cut out breathing noises you make at the beginning and end of syllables particularly Hs and Ss. You can set a gate with the compressor at a sound level, cutting out faint background noise but keeping your voice. The compressor allows you to limit sound that is above a certain dB level, the expander limits sound under that level, called a gate. I'm not sure if Audacity has this, but what you need is a compressor (actually an expander, but they're opposite things built into a tool referred to as a compressor).
