Open the software, and select the "File" tab from the top. Click the "Open" option, and select the location of the file. Import the files one at a time so the program does not freeze.
Right-click the file on "Track 1" and then hold the "Shift" key, and click "Track 2" below it. Both of the files are then highlighted. Click the "Transform" tab at the top of the screen, and select "Filters." Select the " Vocoder" filter from the list of options.
Click the drop-down arrow in the "Control Wave" field, and select the vocal track from the list. Click the "Process Wave" field, which is to the right of "Control Wave," and select the instrument track.
Set the "Output To" field to "4" or the next empty available track. Set the "FFT Size" between "4093-4096" and the "Overlays" field between "5-12."
Set the "Interval Size" between "11ms-30ms" and the "Window Width" with a value of "80-90%." Adjust the "Vocal Crossover" and "Affect Level" as desired by playing the recording preview.
Save the sample by clicking "File" from the top, and then click "Save."
