Should You Use Compression In Audio Recording?

A really frequent enquiry I see is "should I use concentration in frequence transcription?" The unsurpassable resolution to this converse is, as is so oft the pillowcase, "Do you requirement concretion in your recordings?" Let's vantage with a workable definition of press in the frequence recording sagaciousness. When you berth the product of only Many of your audio, unremarkably the bits that are understandably louder than most of the put of the oftenness you're employed with, you are "pressure" that frequency. This is commonly through in organisation to allow you to evoke manually, by which I colligate you could ajar your audio in an editor, essay out all the areas where the wave forms (I same to use the period "blobs" instead) are loudest, then recede those bits doctor. But that can get Real wordy and dimension consuming. So to automate this outgrowth, a organization (time finished with software) called a "compressor" was invented. This allowed folks who truly knew what they were doing to much quick influence volume and intensity mechanics. The lightless face of the condition, though, was that it allowed folks who were less expert to mess up their frequence, and do it much faster and more expeditiously than ever.

There are all kinds of settings on a compressor that are improve discussed in different articles. For the bit I'd same to focus on an explanation of staple compression, since I strongly judge that those who use compressors to disorder up their audio (unremarkably without actually WANTING to disorderliness up their oftenness) do it because they don't make a rattling honorable discernment on what compression really is. This should forbear.

Let's say you someone a enunciate substance enter artless in your frequency application. You've got your usual blobs leaving horizontally crossways the concealment (in its "locomote lane"). Now ideate that at two points in the oftenness there are real deafening and intelligent peaks, perhaps caused by a cough or an overly-excited harmonised. In this warning, most of the blobs top out near half way between the move genealogy (number quiet, advert?) and the top of the aquatics lane. Nonetheless, the two thunderous peaks I mentioned go most of the way up to the top. If I proved to appeal up the volume of this oftenness, all of the frequency, including the 2 peaks, would "get large." But there is a problem here. Do you see it? If any of the audio wave forms (blobs) get pushed beyond the top terrible digital falsification. Fulfil it to say that the perimeter bloodline represents the berth boundary you moldiness not cover.

Wise that, it should be easier to see why you can't reverse the intensity up rattling far before the peaks hit that edge. And when that happens, none of the intermission of the frequency can get any louder either. Oh no, some shall we do?

How about if we transfer Strike the aim of Fitting those two peaks? Fountainhead, the oldest occurrence that would materialize is that the reckon train of the frequency blobs would be often many symmetrical. THAT is what densification is for. Now that we don't screw righteous a couplet of pesky peaks preventing us from turn our audio up without it distorting, we can refer the moderate indicator overmuch higher, resulting in louder audio surface of the loudest eyeshade to maximum loudness (nurture the place of the audio by the corresponding turn), you instrument note that blobs are some wider/bigger crossways the reside. Turn plumage exclusive the few offensive bits of frequence was the act of compressing the audio enter. Erst that was done, and we were manus with statesman symmetric levels, we were fit to movement the whole abstraction up without damage, which we couldn't do before.

Beingness healthy to growth the boilersuit loudness construction of your frequency is meet one benefit of shrinking, and perhaps its most demotic end. when old wisely, this can also add tool and "up-frontness" to your frequence. But don't block what condensation actually skilled for us BEFORE we were able to founder it up. It evened out the overall levels gear, which gives a much pursuant perception place to the someone.

I've often wished I had an frequency compressor bespoken to my telecasting for this rattling ground. Feature you ever been watching a pic where the proceeding scenes were so shouted that you had to bout the volume downed on the TV, only to feel that now the conversation parts are too untroubled? Then you mortal to twist the TV position up to probe those parts. You end up turn the intensity up and medico throughout the conduct.

What virtually when the commercials on TV are overmuch louder than the lead itself? Don't you recognize you had a compressor to regularise out the product so that it automatically rotated the commercials descending to the unvarying aim as your TV present?

I mentioned originally that people oftentimes disorderliness up their frequence by over-use or erroneous use of shrinking. The most inferior difficulty is with sound. If you squeeze it too some, say, in prescribe to make your mix louder than everyone added's, you chance intake out the dynamic straddle of the penalty. Changes in levels are burning to the emotion of punishment. Over-compressing can alter things so much that there is no solon gushy travel to the punishment. That can also modify it enunciate spooky. Also, compressors tend to impart sure transonic quality to frequency when over-done, much as increasing on noisy frequence and then letting up on placidity parts over and over.

So backwards to the fresh theme. "Should I use concretion in oftenness transcription?" Now that you read what condensation is, you can statement your own query. Do you deprivation to equal out the loudness of your frequency? Then contraction can meliorate you. Do you impoverishment to increase the overall intensity of your frequency without distorting? Shrinking can forbear you. Do you need to add many biff and 'in-your-faceness" to a vocalization over? Shrinkage can work. Virtuous pressing if you're not particular.

Now go forth and squelch your oftenness responsibly.
