For more convenient use, Adobe Audition offers 2 audio editing modes, such as Waveform and Multitrack. In the Waveform view, you can easily record audio and adjust its volume. The spectral frequency editing enables you to edit recorded wave in various ways. Audition is a comprehensive toolset that includes multitrack, waveform, and spectral display for creating, mixing, editing, and restoring audio content This powerful audio workstation is designed to aelerate video production workflows and audio finishing — and deliver a polished mix with pristine sound. In this episode of Audio 101, I cover all of the tools and techniques necessary to edit, denoise, effect and process different types of audio in the Spectral.

There are always going to be imperfections in your production audio. Instead of scrapping it, use these tips to clean it up in Adobe Audition.

No matter how experienced your audio crew, there are always issues that will find their way into your recording. It happens. But resist the urge to scrap your audio and go straight to ADR, because you might be able to salvage that audio. There are several options you can utilize in order to save this audio, but one option that’s gaining steam within the industry is Adobe Audition.

With that said, here are five tipsfor cleaning up your audio in Adobe Audition. For each tip, we’ll run through how you can fix the issue and then post a helpful professional tutorial to guide you step by step. Let’s get started.

1. Fix Distorted Audio

There may be moments in post when you discover that your field recorder settings were simply too hot. This is a problem that frequently rears its ugly head in documentary film work, especially for those working as a one-person crew. When your audio is too hot, it’s going to distort — but fear not. It can be fixed.

1. Access the Waveform of your audio by double-clicking on the track.
2. Head over to Window > Amplitude Statistics.
3. A new window will open. Click on the Scan option in the lower left-hand corner.
4. Once it scans, find the section that says Possibly Clipped Samples.
5. Click on the small Diamond Shaped Node next the number. This will take you to where your audio is clipping.

For an in-depth look at how to use the technique above, check out the great tutorial below from Mike Russell. He’ll run through the Amplitude Statistics process, then show you how to fix distortion in two different ways.

2. Use the Spectral Frequency Display

Have you ever been out on location filming and some secondary interference messed with your audio? Maybe someone on set sneezed or had their cell phone ring. Maybe an airplane flew overhead. Noises like these can be taken out of your audio with the Spectral Frequency Display.

1. Open your audio Waveform by double-clicking it in the Files Panel.
2. As the Waveform opens in the Editor Panel, look toward the bottom of the panel.
3. There is a small divider. Click and Hold to pull that divider up, revealing the Spectral Frequency Display.
4. Now you have a visual reference to find the noises you need to take out.

Check out the tutorial below where Maxim Jago from Lynda.com takes us through the step-by-step process of using the Spectral Frequency Display to clean up your audio.

3. Use Adaptive Noise Reduction

Another way to reduce unwanted noise from your audio is through the use of the Adaptive Noise Reduction effect. This effect works really well at removing ambient background noise and wind noise. This effect can be applied in real-time through the Multitrack Editor, which is really handy. Here’s how to get started using the Adaptive Noise Reduction effect.

1. Activate your Waveform by double-clicking your audio source in the Files panel.
2. With your Waveform selected, head over to either the Effects Rack or the Effects Top Menu.
3. Then go to Noise Reduction/Restoration > Adaptive Noise Reduction.

Now that you know how to access the Adaptive Noise Reduction effect, let’s find out how to precisely use the effect to clean up audio. Here’s another video from Lynda.com that runs through the process.

4. Remove Echo

Echo is another issue that you may hear in your audio from time to time. It happens, especially when you’re filming at a location with a lot of reflective surfaces. Surfaces like concrete, tile, brick, and metal will reflect sound and bounce it all over the space, which in turn can give you some unwanted reverb.

Unfortunately, Audition doesn’t include any really polished effects that can handle this issue. However, there are several plugins you can purchase that won’t break the bank. Two great plugins you can use: Acon Digital’s DeVerberate and the SPL De-Verb plugin from Plugin Alliance.

In the tutorial below, Curtis Judd gives us an in-depth tutorial on how to utilize both of the above plugins to reduce and remove echo issues from your audio. Now, you should be completing your audio mix in something other than your NLE, but if it’s a quick video project and you have echo issues, know that you can use these plugins with Adobe Premiere Pro CC.

5. Use Frequency Analysis

Another way to locate noises in your audio is by using the FrequencyAnalysis option. By activating this window, you’ll be able to see the frequencies in your audio file, which then allows you to find where random issues of clipping, excessive bass, and other noises are located. Here’s how to access this menu option.

1. Go to the Window top menu, and click the Frequency Analysis tab.
2. Choose Logarithmic from the Scale drop-down menu.
3. Start your playback. To Freeze, click one of the eight Hold buttons.

Now that you know how to access Frequency Analysis (as well as how to apply frequency holds), let’s turn to a full tutorial (once again from Mike Russell) on how to effectively use this feature for audio clean up.
