In Audacity, you can approach this in at least two ways, depending on the nature of the bit you want to silence and the surrounding material. The simple way is to highlight the section of the track / channel and select "Generate... Silence" from the menu. The suggested duration will be the length of your selection. This is a harsh edit, and very likely ...

Audacity is a great tool for this kind of work. You might be able to make a slightly better sound using a sampler that can crossfade across different sounds for different pitches, but I'm not sure if the result would be worth the extra effort. It sounds to me like the problem with your "current best" is that you either aren't looking for zero crossings when ...

I can see two reasons why you'd use a gate while recording instead of in editing : 1. You're broadcasting live. 2. You're using outboard equipment. A gate should, generally, be first in your audio chain but in your case you might want to put it after your noise reduction. You never want to put it after the compressor! If you do it in editing you have ...

The separation of instruments from a mix is something that seems easy to us. Humans can concentrate, for example, on a specific instrument being played in an orchestra. We can do this because we are very good at grouping harmonics into a 'tone', and associating characteristic timbre with an instrument. We are also good at filling in what isn't there with ...

Quick answer - No I haven't heard of any but I've heard about research being done on the field. The greatest theoretical problem with de-mixing is knowing what to subtract. When we mix, we add A and B which are both known signals. But when we try to do the opposite, we need to know in advance what B is. This would render the process useless in most cases ...

It kinda matters what order you put them in but everyone has a different order that they like and then sometimes you adjust for issues. Most Channel strips let you change the order of at least some of the modules. I tend to default to EQ/DYN/De-es/multiband but everyone is different. Sometimes you might need 2 of certain processes, 1 to fix an issue, ...

MountainX, I don't know if you ever got the answer you needed but I just found out how to do it. If you have a stereo recording in Audacity you click on "Audio Track" at the left of the stereo channel you're looking for. You'll see Split Stereo Track in the drop down menu and then you can edit a specific segment of the audio in that channel alone

I think the leaders in this field are without a doubt iZotope and Zynaptiq. iZotope RX is just the most incredible tool for separating sounds using FFT and spectrographic analysis: https://www.izotope.com/en/products/repair-and-edit/rx.html To see what it's really capable of you should check out the work that Michael Wabro did separating the soundtrack and ...

Recording it yourself is definitely the best and easiest way. You will just have to see if your equipment is up to it, though it's not a difficult sound to record so you may be ok. Portable recorders are so cheap now it's worth investing in one if you do this kind of work regularly. One technique you could try with your sound is to make a copy, reverse it ...

I would apply them in order of de-esser, EQ and compressor. The first two could be done in either order, but the compressor should generally be last. You could EQ with or without the De-esser applied, but the De-esser will offer you less control over the sound than a good EQ. The compression should be last because it deals with overall signal power, which ...

There are enough patches in the recording with the hum and without the voice to use a noise removal tool -- Audacity has one built in and the LADSPA plugins provide this kind of thing. I'd be shocked if the likes of Protools, Logic etc didn't have such a thing. As the comment mentions below, the noise is sampled and then its audio spectrum removed from the ...

"i'm afraid i could confuse a low amplitude region with an empty one" Hiya, if you delete the "Audio Files" folder after spotting all offline clips will be greyed out. The recordings have a colour, so you will easily be able to tell what's a spot clip and what's a recording.

A show usually has a leader reference tone and also has pops, known as sync pops or head pops (versus tail pops) or casually just called "2 pop". The reference tone is in regard to calibration level, the 2 pop is (secondarily for calibration) but primarily for ensuring sync - especially when we';re talking about ProTools sessions containing the ...

If the vocals are in different languages then no, there is nothing that can be done to cancel them out automatically. If the different lyrics have gaps in different places then you could manually select these gaps using a DAW and drop them into a "master" version.

My website, monotoSTEREO.info, and its companion Facebook page may be of interest. It is dedicated to providing a collection of resources on audio upmixing using processes such as source separation and spectral editing, with links to over 1,000 research papers, presentations, etc. in the field as well as media samples.

I'm afraid what you are asking for could be the equivalent of taking a Victoria sponge cake & asking for the flour, sugar, butter & eggs back in separate bowls. If there are clear spaces between each person speaking, you have a chance; any audio editor such as Audacity [freeware] can be used to [manually] split the audio at each gap, then move each ...

What you are asking for is pretty much like trying to take the sugar of a baked cake. There are tools that could help but I have no personal experience with them. From what I was told, iZotope RX can work some magic. I think they have a trial version, but I don't know how limited it is. Using a software like audacity or reaper you can also put a hi-pass ...

This is a really general answer and you may get better ideas by chatting with someone in person but: I think this is a really classical example of balancing time, effort and economics (how much are you asking for, how much are the others asking for). It's really just something that you need to balance, so that it feels good for you and others that are ...

My son used MultiPlay for a show last year. He is a teacher. He had his students run the program for cueing through the show. It worked really well. It's Windows only. http://www.da-share.com/software/multiplay/ MultiPlay is a Windows based program designed to play audio cues for theatre or corporate use. It is free to use in both amateur and commercial ...

If you can get access to mac just use Qlab! It works great and for stereo playback, which I'm guessing is what you're looking for, it's totally free...

I realize this comes a bit late, but what the heck.... I've run into this same phenomenon. What's happening is a natural result of using the Denoiser audio plug-in in Adobe Premiere. Unfortunately, it takes about 4 seconds for Premiere to "learn" the noise print of a clip. That is why you're hearing about 4 seconds of static and unwanted background noise ...

for normalization in todays crowded market - where we are experiencing "loudness wars" you do not want to be normalizing to peak levels. You normalise to a loudness standard. There is an open-source project that will achieve this for you - bs1770gain which is the updated version of r128gain. This will normalize to a loudness level and will thus consider ...

DAWs are not intrinsically harder to use than NLEs. The thing is that most people really don't know their NLE either. Most consumers and beginners don't use many advanced features of their NLE. Since video is visual, people are inherently better at separating out and visualizing what is happening with multiple layers and accomplish what they want without ...

You choose when to stop, Original file (as downloaded from Vocaroo) First, a cut at 8 kHz... Audio after 8 kHz cut Next, a 70 Hz high-pass... Audio after 8 kHz cut and 70 Hz high-pass And just for fun a pass of iZotope's "Dialogue Denoiser" (auto setting)... Audio after 8 kHz cut, 70 Hz high-pass, and Dialogue Denoiser

As others have said, this is the expected behavior. Your computer mic input is a stereo mic jack that takes signal from the mono mic on both channels by nature of the connector design. (On a mono 1/8" connector, the ring contact will touch the sleeve of a mono connector.) Your Focusrite on the other hand has two distinct inputs, not a L/R configuration. ...

I'd be more inclined to remove the white noise from the speech than try add it back in the silence. There are some very good paid plugins that can do it - personally I use a lot of the Waves plugs, X-Noise etc - but there are freeware alternatives. Noise Reduction is one that Google turned up. Untested but for free you can try it & see if it's any good ...

What is best to do if you record something specific is also record the room 'silent', so than you get the environment sound of the subject your recording. Add these layers together and you'll get your 'white noise' in a less artificial way.

Welcome, good question! If your recording atmospheres why are you recording only 1-3 minutes? An atmosphere develops over time and has interesting changes in it's sound, I'd advice to at least record 5 minutes. 10 minutes is even better. And chopping on in PT11 is fine, as long as you haven't change perspective in the recordings. You could use 'strip silence'...

Mess around with EQ. Try lowering the treble a bit to muffle the sound. Normally, you would put a low pass filter on to make it sound a bit muffled. As for talking to him\herself, Increase the bass a bit, and do not apply reverb to it. In film, we typically have room tone, reverb and shave off most of the low frequencies to give it the sound of being in a ...
