Audio software compressors and audio output filtering

"Speaker problem: Use headphones. The cleaner the audio to begin with the better it is to work with later. Most audio professionals I know say to avoid any noise reduction as it can and does affect what you want to keep. If you still have noise you need to eliminate after listening via headphones, your best option is to use a noise gate (either hardware or software).

Microphone Compression: Most decent DAW applications (or audio editing) applications can work in a live environment and do similar to what you are talking about in software. However that can only do so much. Mic technique is critical for good sounding audio. If you need to move around the room invest in either a wireless mic/headphone combo or a very long cord for a wired headset.

To me, it sounds like based on what you are saying you need to invest in a headset of some sort."
