Double-click the Pro Tools desktop icon. Pro Tools may take a few seconds to fully launch. Depending on how you have Pro Tools configured, either a new session or the last used session will automatically open. To open a new session from a work in progress, click "File" and select "Open New." To open a work in progress from a brand new session, click "File" and select "Open Recent."
Click "File" and select "New Audio." This opens a blank audio channel. Do this once for each audio track to be edited.
Double click where it says "Audio 1" to name the new channel. Do the same for subsequent audio channels.
Click on the first channel. This assigns subsequent actions to that channel until you click on another one. Import the audio to be synced. Click "File," "Import Audio" and select the files from the browser which opens up. This automatically opens the audio in the selected audio channel. Click on the next channel and repeat.
Click "Effects" and select "VocALign." A separate VocALign interface will open with two windows. Drag the first audio into the first space and the second audio into the second window.
Click on "Waveform" graphic on the top left of the interface. This tells VocALign to align the audio. VocALign works by matching the energy patterns of the audio wave form. Click "Save" and select a save destination, for example "Desktop." This renders the pair of audio files as one file.
Click "File" and select "New Audio." Click "Import" and select the aligned audio file you saved to your desktop.
