How much money have you got to spend & would you consider replacing the floor entirely with a new one made of solid concrete, not connected to the current walls or floor? That is not as frivolous a question as it may seem. Audio separation, especially at low frequencies, can only be achieved by mass & air-gapping. You could generate a bit of an ...

They missed out one vital piece of information - at what frequencies? They'd need to be made of lead to stop anything below 100Hz… I wonder whether their mosquito-repellant curtains work when they're open too ;-)

I would imagine the remixer was provided with a vocal stem.

Audacity has a Truncate Silence effect (Effect > Truncate Silence...) which should be able to do what you want: There are many other alternatives in other applications - but these are for Windows or OSX. I'll list them here for other users with same question but different host/OS needs: Pro Tools - Strip Silence Reaper - Dynamic Split Cubase - Cut head ...

If you want it to be really quiet and wont be accessing the amps after they are installed, your best bet might be to just put them in a seperate room so that it will be acoustically isolated completely. If they are in the same room, you might want a case with a door to reduce the sound the amps produce.

In the case where your two audio signals S1[n] and S2[n] are of same length, and we are speaking of discrete time, discrete value signals, the DFT being a linear transform : DFT (S1[n] - S2[n]) = DFT(S1[n]) - DFT(S2[n]) It means that subtracting the spectrum of S2[n] from the spectrum of S1[n] and transform back into time domain signal will produce the ...

My short answer would be that it is virtually impossible but depends on how good results you expect. The solution your intuition draws you to, and which would work in certain cases, is phase cancellation. Basically, if you have two sound sources, exactly the same, and reverse the polarity of one they will cancel each other out. The simplest example of this ...

Evan if there is, it would be most likely based on stereo cancellation and eq-ing so it might be a better idea do them the proper way instead of relying on software

Honestly, I think you'd have a much simpler task if you tried some de-clicker software on the best of the pair than attempt to keep two independently-recorded analogue tracks in prefect phase-sync for three minutes whilst cross-cutting by eye. I know of no software that could automate your chosen task. My de-clicker of choice is Waves X-Click Two others I'...

Many handheld recorders have a feature that automatically starts a recording when a certain dB threshold is reached. That might save some time and file space. You'll have individual files of hopefully just whatever alien language your girlfriend is speaking! I know the Zoom H4n has this feature. I'm sure cheaper ones do as well. Zoom calls the feature Auto-...

Use a gate! The following process will let you isolate what you need. First of all find the frequency of the voice, i suspect for a female voice an area between 250-800 should capture the main body of the voice. Roll overs and sorting should be in a different spectrum. Ater finding that area cut everything else and just bandpass that area. (you can ...

I would approach this from the perspective of having a rigid coupling between the seat, the drummer and the entire kit. Consequently, I think you would need a "floating" floor setup that can be isolated from the building using some sort of spring/dampening structure. I have not seen the 'tennis-ball' platform other than in this video ...

Well I'm not a consultant but what you are probably looking for is a dB meter and I would guess there's not really any reason to measure frequencies other than curiosity. If you are considering measuring frequency because you know that human ears are less sensitive to certain frequencies then consider using a meter with an A-weighted option. A Weighting ...

What microphone and what working distance are you using? The ultimate goal is maximizing the "Signal to Noise Ratio" (SNR) There are TWO ways of doing that, and typicaly you can use a combination of BOTH methods: MINIMIZE the external NOISE. That means blocking noise from coming into your recording space. The ONLY thing that blocks noise is MASS. Not foam, ...

i don't think you are in a bad situation at all. first of all a very usefull forum by mr John Sayers. http://johnlsayers.com/phpBB2/index.php <- read a lot here! Blocking the sound needs mass as stated but there are solutions that don't require 1meter o cement just to block some noise. What you'll need is neoprene blocks , gypsum boards , and ...

Sound is blocked only by mass. Either solid mass, or air mass (over a distance). Of the two alternatives you have shown, certainly you have more chance of success with the solid option vs the hollow option. If you were dealing with nearby (physically conducted) higher-frequency sound, then the air-gap might be of some benefit. But you are dealing with large-...

Many professional sound recording crew on big-budget productions use their earbuds with hearing-protectors over the top for critical monitoring in high noise situations. The COMFORT factor will be more a factor of the earbuds vs. the hearing protectors. Of course there are cheap, uncomfortable hearing protectors just as there are cheap, uncomfortable ...

While having tried those stuff only once - I'm not sure they are really that comfortable. An usual place one might find them is on construction sites where drilling is required or on a shooting range - perhaps a hardware store might have some on display for testing

There is no way to do what you want. Human voice, no matter what voice timbre people have, is pretty much in the same frequency range. That said, you can at least filter out some of background noise by equalizing out frequencies that do not occur in human voice. There is a good article on voice frequency on Wikipedia: https://en.m.wikipedia.org/wiki/...

Adobe Audition has a built in Noise Reduction effect that works really well. Effects>Noise Reduction/Restoration. You can use this to capture the noise profile of the background music or other sounds you want to remove. Just find the longest section where only the unwanted sound is playing in isolation, and grab this. The longer the selection, the more ...

On very few occasions you may be able to extract the center track from a song cleanly, which is usually the vocals and basic instruments like drums which can be somewhat EQ-ed out. In this case, however, you may do what the remixing artist most likely did and find the stem on www.acapellas4u.co.uk where it is currently listed as an available acapella track. ...

Summary: Use a noise removal plugin that can learn noise to produce a track with one person "noisereduced" and use this track as sidechain source for a noise gate. Here is how to achieve it with a noise removal plugin that can learn a sample, some EQ and a sidechainable noise gate: Make two empty tracks and four copies of the track and name them like so: ...

You probably already thought of this, but if there is a common sound/signal frequency wise, simply taking the average of all the FFTs will attenuate the uncommon parts, while the common part remains roughly the same level. The spectrum plot below illustrates that - in the center section you see an average of that period. The lines (the common signal) ...


1

Use a noise gate with a fast attack and medium release. So long as the threshhold is above the floor noise/background noise, it will cut off any sound during the silent parts of the track. There are other ways such as noted below, in Cubase its called a "DeNoiser". However, it comes at a slight sacrifice of certain frequencies within the audio, so I would ...

Don't put equipment that makes noise in the room that you are sampling audio from. There shouldn't be anything at all in the room. Preferably even the ventilation should be independent so you can shut it down during recording. (I've often seen where they just put an A/C unit in a window and block off all the other vents.) That's always going to get you ...

I say you give your ears a break so that they're well rested for a more suitable critical listening environment. If you're taking the time to work on the train, I'd personally work on non-audio aspects of work. Get back to emails, catch up on SSD or blogs, manage your backup database. There's all manner of things that need to happen in what we do that don't ...

If you are familiar with the industry-standard Sony MDR7506, in terms of sound, then you should look into the Remote Audio HN-7506 High Noise Environment Headset Monitor. These are commonly used in recording loud sources in the field, and they may color the sound less than actual noise-canceling headphones (which I can never bring myself to use).


1

I can't remember the name of the model, but Beyer has headphones dedicated for drummers and other people needing high isolation as well! It was a long time since I tried them out, but what I remember they sounded pretty much like the 250's, which happens to be my weapon of choice as well.

It is pretty difficult to isolate sounds in a crowded soundscape once they have been recorded without making them sound unnatural. The best solution really is to get the sounds isolated when you are recording them. Using shotgun mics,getting close etc where possible. Otherwise, record your basic sound track and then add in sound effects later, blending them ...
