Equalization using barcode generating for none control to generate, create none image in none applications. Visual Studio 2010 Just like wit none none h your home stereo, you can change the Bass, Treble and Balance information captured in your voice track recording all considered frequency types in audio. Equalization is the process of manipulating these frequencies by increasing some and decreasing others, in order to get the desired sound that you want, and for the best audio from a wide range of speaker options. To access the Equalization settings, go to the main menu and select Effect and then Equalization.

. [ 170 ]. 9 . A graph is displayed, showing all of the detailed equalization factors. The previous none for none graph is the "Curve" view of Equalization. You can also view this information in a Graphic or Bar view, or a Linear View. Let"s discuss the Curve view first.

Because this is a graph it has a vertical axis along the left-most side and a horizontal axis along the bottom. The Vertical focuses on the amplification gain in the audio, and is in decibels. The Horizontal axis or scale is in Hertz, and shows the frequencies where volume adjustments will be made.

Bass (low) frequencies are on the left-hand side, midrange frequencies in the middle, and the treble (high) frequencies are on the right-hand side. The two lines within the graph are blue and green curves. The blue line has a number of white circles, or control points that are moveable.

Click-and-drag any control point up to increase the volume of that frequency, or down to decrease the volume (or drag a control point off the graph completely to remove it).. [ 171 ]. Giving Your Audio Some Depth: Applying Effects So, if you wa nt to increase the bass, you can move a control point on the left-hand side of the graph upward to make the change. Decreasing treble, or high frequencies would mean taking control points on the right-hand side of the graph and moving them downward. You"ll see the changes happen on the thick blue curve immediately.

The thin green curve is actually what Audacity uses to process the equalization effect. It attempts to keep the thin green curve as close to the thick blue curve as possible, but will adjust if there are sudden changes in amplitude or frequencies. You can also use the Graphic EQ (Equalization) mode to make adjustments to the thick blue line a bit more easily.

You just move sliders up and down much like a home stereo equalizer and switch back to the Curve mode, and you will see that the thick blue line has changed to reflect the changes you made. Here"s some general guidelines to look at to get started with equalization: For more rich and full sound, increase or amplify bass frequencies. Increase the volume of treble frequencies to create a more clear sound.

Change frequencies in small steps until you like the sound of what you hear. Try adding treble for each frequency. If you don"t hear improvements, then switch to bass and try the same.

Adjusting frequencies for voice will require some testing. If frequencies are set too low, the voices will sound "boomy", too high, they can sound too hollow. Try to decrease the low frequencies and increasing in the 1 to 5 kilohertz range for a bit more clarity.

. Using Equaliz none none ation is really a matter of trail and error. It takes a practiced ear and practical experience for finding out what best works for your recording environment. Listen carefully, test and manipulate to find the best sound.

. Fading In and Out As we explain none for none ed in 8, Importing and Adding Background Music, you can use Fade In and Out for background music. Here"s the basics about how you"d use either feature (but feel free to refer to 8, Importing and Adding Background Music, for all the little details). 1.

From an audio track, use the Select Tool, and select a small portion of the audio track. 2. Next, from the Audacity main menu, select Effect and then Fade Out or Fade In.

The sound waves in the selected portion will go from large to small (loud to soft) and eventually to silence, or vice versa, if you chose to Fade In.. [ 172 ].
