This is known as clipping and is extremely undesirable. Oftentimes, a portion of our audio will extend far enough north that it crosses into the red.

You'll want the volume at about -6 decibels with peaks approaching, but not hitting, zero. When you think you've got it, stop looping and play your clip through on the time line as you watch the audio meters. Use the MakeUp control to restore gain lost due to compression. After making adjustments you may find that the volume has been reduced. Avoid over compression as this can result in a dulling effect due to the reduction of the higher frequencies. This should put you in the ballpark and you can fine tune from there. Start by setting Ratio to around 2-1/2 to 3 and Threshold between -8 and -14. Make sure Compressor is checked at the top. The Compressor controls make up the middle section of the graphic interface. Listen carefully through a set of quality headphones while making adjustments so you can hear exactly the effect your adjustments are making. Click the Toggle looping audio playback followed by the Play only the audio for this clip buttons located in the lower right portion of the Effect Controls window to loop your audio clip. Attack determines how quickly the effect will kick in after the Threshold has been breached and Release refers to how quickly the effect will stop working. For example, if Ratio is set to 3, or a ratio of 3 to 1, then as the input level increases by 3 decibels the output increases by only 1 decibel. Threshold sets the level at which processing begins and Ratio controls the degree of processing that will take place. The Dynamics effect consists of several different, yet similar, audio processing effects having similarly labeled controls. Twirl it open and you'll see a graphic interface reminiscent of a hardware based compressor/ limiter. The rest of us, however, will do just fine with Custom Setup. Twirl open Individual Parameters for an array of fine tuning options that an audio engineer's dreams are made of. Below Bypass are Custom Setup and Individual Parameters.

Twirl the effect open and you'll see a checkbox labeled Bypass, which allows you to toggle your adjustments on and off so you can hear the effect they are having. Drag Dynamics onto your audio clip, then find it in the Effect Controls window. Choose Dynamics from the folder that matches the type of audio track your mix is located on: 5.1 surround sound, stereo or mono. The Audio Effects folder opens, as well as three sub-folders, each displaying the Dynamics effect. With your project open in Premiere go to the search textbox in the Effects window and type Dynamics.

Most editing software will have similar capabilities and dedicated audio editors will have an even more extensive tool set available.

In this tutorial we'll be using Adobe's Premiere Pro CS5 to demonstrate these tools. It softens the loud parts and boosts the soft ones to create a more even sound. A compressor is used to even out the audio waveform by compressing it so it conforms to values specified by you. This uneven audio mix can cause your audience to ride the volume controls in order to hear the softer portions without being blown out of the room by the louder ones - an annoying requirement at best. Sometimes these encompass both extremes from the highest highs to the lowest lows. Let's take a look at some of the tools commonly used to do this.ДЄ typical audio waveform is filled with peaks and valleys. In reality, a lot of work goes into achieving a finely tuned audio mix worthy of an audience's time. Wouldn't it be wonderful if we could simply record our various audio assets, drop them onto our time line, export to our preferred distribution medium and call it a day? Of course, we could do exactly that, but then our work wouldn't have that high degree of professionalism we constantly strive for.

Now for that final, professional touch,we'll show you how to ensure that your audio is well balanced and free of both low end noise and high end distortion by using compressors, limiters and noise gates to sound its very best. At last, you've finished recording all the various components of your audio track and have them carefully assembled in your time line.
