Double-click the Mixcraft desktop icon to launch the program. It may take a few seconds to fully load.
Click "File," "Open." Select the project containing the vocal audio you want to edit.
Hit "Play." Click the "S" icon on each channel in turn. The "S" icon stands for "Solo." This enables you to hear each track in isolation so you can determine which vocal tracks you want to edit.
Click on the vocal audio to highlight it. The vocal audio file is represented by a series of peaks and dips. These represent the volume pattern of the audio. Use the volume peaks as a guide for locating the start and end of vocal phrases. For example, it's quite likely that the largest peak after a flat line represents the start of a new phrase.
Hover the mouse over the audio file where you want the trimmed section to start. This brings up a horizontal arrow icon.
Click and drag the arrow to the right. This pulls the audio file in from the edge, silencing the audio.
Hover the mouse over the audio where you want the trimmed section to end and drag from that side.
Select a vocal audio file to be stretched. Stretching a slow vocal audio can make it fit to a slower tempo.
Press and hold the "Ctrl" key on your keyboard.
Hover the mouse over the right edge of the audio file you want to stretch.
Drag the edge of the clip to the right. A small box appears telling you the original length of the clip and the length of the stretched clip.
Click on the vocal audio to be shifted. Pitch shifting lets you alter the vocal so it fits into a different key. This is convenient if you have a vocal recording and want to use it with a different backing track.
Click on the "Sound Details" tab. Select "Adjust Pitch By." Select "Semitones."
Click on the up or down arrow to select the amount of semitones and in what pitch direction you want to edit the vocal. For example, to change a vocal from C sharp to C, click the down arrow once.
