So if you find yourself guilty of.
May 12, 2018 Clipping in dialogue recordings is often a consequence of a lack of headroom in the recording equipment. The De-clip module in iZotope’s RX audio repair software is designed to help repair analog and digital distortion by redrawing squared off waveforms.

Getting familiar with Spectral Repair can have you up and running quickly, solving problems like squeaky guitar tracks, which means you can go from a squeaky guitar track like this…

Spectral Repair intelligently removes undesired sounds from a file with natural sounding results.

This tool treats selections from within the spectrogram waveform display as corrupted audio that will be repaired using information from outside of the selection.

For example, in this file, noisy guitar squeaks can be heard as the player changes chords.

To reduce the severity of those squeaks, I’m going to use the attenuate feature in the Spectral Repair module, which reduces spectrogram magnitudes in the selected area to match magnitudes in the surrounding areas, resulting in the removal of the sound without leaving an audible gap behind.

I’m going to click R to switch to the time frequency selection tool, and make a selection where the first string squeak is occurring.

Once I’ve made my selection, I can preview only the frequency content that I’ve selected by pressing this play button down here.

Now, I’m going to make some choices about where to set the parameters of the attenuation tab. Surrounding region length determines how far around the selection Spectral Repair will look for a good signal.

Watch what happens to the handles, or the wings outside of my selected region as I move the slider of the surrounding region length. First of all, they’re moving vertically. That’s because the direction of interpolation is set to look for information to interpolate north and south of my selection.

If I had direction interpolation set to horizontal, it would extend those handles left and right, or east and west of my selection. Now, because there’s loud signal material left and right of my selection, it makes sense to keep the direction of interpolation vertical. I should add that 2D will create handles north, south, east, and west of the selected area.

Before and after weighting gives more weight to the surrounding audio before or after the selection. In this case, I’m going to move the slider to a value of 8, because it looks as though frequency content far south of my selection is occupied by low end rumble, or hum from the instrument.

Finally, strength adjusts the intensity of the attenuation. In my case, I don’t want to over attenuate the squeaks, so I’m going to leave it where it is at its default setting of one.

Now, I’ll press process.

Now let’s play back that sample after I’ve attenuated the guitar squeak using the attenuate feature in spectral repair.

So for context, here is before.

And here’s after.

As you can hear, that squeak has been attenuated. Spectral repair can also be useful for attenuating noises that interfere with a performance. Like in this example, where a beeping truck is competing with the sound of an acoustic guitar.

By switching to the time and frequency selection tool by pressing R, we can identify exactly where the unwanted sound is occurring in the spectrogram and select it.

If I use the other playback button, we’ll hear what is inside of my selection and outside of it, too.

I’m not hearing anything but the sound of the beeping truck, so now I’ll open Spectral Repair, and use it in attenuate mode, which removes sounds by comparing what’s inside a selection to what’s outside of it. In other words, I’m going to use attenuate to bring the truck beeping down to a level where it’s inaudible, and blends in with the background noise.

I’ve chosen a number of parameters here, but maybe most important is to go with vertical mode, so the information above and below my selection is used to repair the audio. Now let’s hit process.

Now, this is a very noisy truck sound, so I’m going to press process once more and do another pass to really make sure that the truck beeping is properly attenuated.

Now, let’s listen back to our results after using a few passes of attenuate.

From tire screeches to dog barks and public transit beeps, noise is a consistent fixture of the city soundscape. While these sounds tend to blend into the background of daily life, they are hard to ignore when captured by a microphone.

For this reason, noise reduction is a necessary part of making music. In a given session, we clean up hiss and rumble from home recordings, pull out clicks and pops from vocal performances, and dull pinging frequencies that poke out too far in the mix.

But we don’t always need to be so critical of noise. Since the beginning of recording history, it has been used to enhance instruments and even create new categories of music. Furthermore, too much noise reduction can strip a sound of its natural character.

To reflect this, we’ll look at the different types of noise common in audio and how to make the call to keep or remove them. While the tips will be from the perspective of music production, they are also applicable to post for film and TV.

Types of noise

There are many different kinds of noise that can disrupt music. If you can identify the type of noise it is, you will have an easier time picking an appropriate removal tool. Here are five noise categories and the RX 7 modules to remedy them.

Impulse noises are short clicks and pops that vary in frequency and loudness throughout a recording. Mouth noises fall into this category and they are almost always removed due to their distracting quality. Some artists, however, deliberately include intermittent crackle and scratches in their music for a vintage effect or as part of a glitch sequence. RX Repair Assistant makes it easy to detect and eliminate clicks (as well as clipping, noise, and more).
