Record one long shot. Split it from the half. Put one half to the right channel and the other to left channel. Export a stereo file. This way you will get a very wide stereo image that is hard to get from a stereo field recording and your sounds in the front will be clearly distinct from ambience. Do not just transform to stereo. If you do that, you will ...

Record 2 mono claps/pulses/shots, however you're generating it. Move the mic from one side of the room to the other for each, keeping each at the same distance from the source. Match up the initial claps later, save as stereo. It won't be perfect, but no-one except you will ever know ;-)

If you mean just the dialog, you'd do better starting from the 5.1 audio as a source. The centre channel should be dialog only. If you want to include the music, or if you only have the audio as stereo, then it's not possible. You cannot unbake a cake. Late Edit: There is now the very good yet very expensive Izotope RX which has a "Music Rebalance" plugin ...

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 ...

This is not my forte by any means, but a few thoughts come to mind... Air traffic. Planes, helicopters? You did mention planes though... Water fountain? Music? playing in passing cars, out a window Conversations? Utilities? steam vents, transformer buzz? Street vendors? calling out wares etc. Not sure how many of these would fall under the 'anxiety ...

Ding dong! Metro/subway/train doors opening, is one of my favorite city sounds. But I'm assuming you're dealing with exterior shots based on the ideas you've thrown out already. How about that muffled bassy thump that you can hear in a passing car or outside a club? That's the "pulse" of the city, and it's never far away even in the middle of the day. ...

If the two characters' dialog is panned centre in the mix then it should be possible. Separate the song into left and right channels, then phase reverse one channel. When you sum the audio back together, you'll cancel any material that previously appeared in both the left and right channels equally (i.e. hopefully the centre panned dialog). Now hopefully ...

Each of those numbers is the main frequency that you can change the volume of. You need practice (with your ear) to figure out what freq does what in your case, you just need to know that you only change frequency levels and nothing more (for start, Ι assume that if you don't know what those numbers are, you probably don't try nothing more complicated). You ...

I think what you're looking for is only to be found in CSI [city of your choice] not in real life. Izotope is about as good as it gets, but it needs a reasonably constant noise-floor to suppress. You could try a multi-band compressor to lift everything to the same level, but you'd be unlikely to be able to push the foreground conversation back far enough ...

What you are proposing cannot be done. Your only option is to use something like the 'dialogue isolate' feature of Izotope RX to isolate the dialogue in each of the files, then compare one result with the other to pick the best outcome. It is not possible to 'extract a pure version' of the dialogue because although the dialogue is 'similar', there is no ...

Not sure if I got your question correctly. But if what you're trying to achive is the sole background music without the vocals why don't you just extract the vocals by cancellation as already described by you and afterwards cancel out the vocal from the original track with the vocal that you extracted? Due to the left over backgound noises and degradation ...

Without going into too much detail, the result you seek cannot be achieved in this way. The technique you are referring to is often used to recover "uncommon" information - you are seeking the reverse.

What you are describing sounds like an graphic equalizer, similar to this: [1]: https://commons.wikimedia.org/wiki/File:Graphic_equalizer.jpg These are used to adjust the signal strength of specific frequencies to limits of +/- 6 or 12 dB per frequency. If you move the bar labeled 910 to the bottom it means that you have reduced an area focused on the ...

I suspect that the 1kHz tone might be a DC-DC converter and/or insufficiently filtered noise from the +5V USB rail. The specs talk about "14mm condenser capsules". The price tag would suggest electret condensers (which could be operated at a nominal voltage of +5V, requiring very good decoupling from the digital ground and supply rail). If they use true ...

I don't think you'll find a method that completely removes the backing, but you may be able to reduce the volume enough for an acceptable result: You simply put all the all the different versions on a track each in a multitrack program like Reaper, Cubase or Pro Tools. Make sure you precisely align the songs so the wave curves follow each other at sample ...

I don't fully understand the question. I think you could be confused about what a DJ does. Also, mixing songs as a DJ is a form of art, so basically anything can be done, as long as it sounds good to you. But you seem like you want an explanation of traditional, smooth song crossover mixing. So firstly, to make this answer a full one I'll try to explain it ...

Todd is right about the frequency overlap in his first OP reply comment, meaning simple EQing may not get you the results you require. However, something else to note is that the main vocals are commonly centered, spacially. So extracting this 'centre channel' will remove the unwanted side channels from the stereo file. The bass is also commonly centred, so ...

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 ...

Additionally to JoshP's suggestions, general energetic crowd noises and street musicians can add character.

It could very well be related to windows audio settings. Windows can artificially boost the gain of an audio input device within software. This setting is located in Control Panel>Sound Click the "Recording" tab, then click on your desired audio device to highlight it, then click the "Properties" button Under the "Levels" tab you may have settings for ...

I've personally cut quite a few of these. They cropped up on Nikita often as well. My opinion is to break it down into it's main food groups: normal BG (the BG without the press conference - the roomtones or airs, birds traffic if outside, etc) walla bed walla callouts camz bed camz onscreen movement/knockabout The walla will have to be shaped for the ...

Wow that is a crazy post production/forensic/restauration job. The problem is that the signal is very little. What you can do is you can use volume envelopes to increase the directors voice. So that you push the level in-between the hosts words. Then there will be an extreme amount of background noise. Sou you can use a restoration plug in like stylus rx or ...
