Help me better understand Noise Gates
Scott Soderlund wrote:
Hi, I recently started working on a project where the computer captures samples of someones's speech. Each of these samples is run through a noise gate to improve the quality of the sample. I've done a lot of reading to figure out how noise gates work and have pretty much come up with that they help to lower the perceived background noise. Is this correct? In my case, I've got a checkbox that is checked to start running the samples through the noise gate. There is also a slider bar that adjusts the threshold from 0 to 100. The comments I've found inside the program indicate that the "0 to 100" is supposed to represent the percentage of total signal strength. Is this likely correct? What does this mean? I understand that when I change the threshold that everything above the threshold is supposed to get louder, but how does this relate to the total signal strength (and the threshold being somewhere in between 0 and 100)? Thanks in advance for any advice! Scott In layman's terms: If a sound is "35" or louder (35 being an arbitrary number, which would usually be in dB anyway, no?), the signal passes through with no change. If the level is quieter than "35", the gate closes and no sound passes through. Ergo, when someone is talking, the gate is open and nothing's different to the original recording; when they stop talking and all you can hear is the background noise, the gate closes and you hear silence. -- TJ Hertz http://www.whatyourenot.com |

Think of it like this, you walk into a room and the light switch will only come on at a particular loudness, lets say as loud as the sound when you just slamed the door. It turns on the light and you walk across the room to the other door open it and slam it closed and the light go's out. Ok I've got one- you're God ok? and if you only want saints in heaven you would set your pearly gates threshold really high but if your willing to let republicans in you would set your threshold really low. However even at the high saints-only pearly gates setting some republicans would still get in if they enter at the same time as the saints but you (God) will not notice them as much. |

Help me better understand Noise Gates
I've done something with a studio talkback mic where it would duck as
soon as signal from some instrument that would did not have a mic or was in the same room as the talkback mic started playing.I believe I used a Valleypeople Dynamite(more of a compressor than a gate but still in the dynamic proccessing family) -hook the instrument signal into the key input and set it to duck. Most compressors with key ins would make this possible. I wouldn't recomend this for live to 2 sessions however. But isn't this ultimately what most talkback switches do to a mixers control room outs? Ducking the signal to the monitors when the talkback button is pressed so that the monitors don't feed back through the talkback mic? Or is it normally just a complete bypass without the ducking? |

I just reread my earlier posting and realize I wasn't clear on
function: The reason for this setup is so the room talkback mic cuts out during a take and is up between takes without having to turn the room mic on and off manually. I really only did this back when I was assisting and had more time to tweak the setup in bypass. OK. I understand now, and that's a pretty nifty idea! When you said talkback I was picturing a gooseneck or a mic built into the console, not the talkback being used by the performers. Thanks for the clarification. -Paul |
