Hi
First load your voice changing software plug in your microphone and check the levels are OK and the effect you want is suitable. Although you can record a wav file directly to your PC and then add it as a sound file to your video, you can also add narration directly to your film using MorphVOX.
Set MorphVOX running and plug in your microphone. Open VP and add your project to the timeline. Place the cursor to where you want to narrate from and click the small down arrow next to the "Record" tab on the toolbar. Select "Narrate" from the drop down menu.
This will open the "Narration" video pane containing the Red start button, the Stop button and the recording level line.
At the top right are boxes showing the sound devices available etc.. The defaults (on my system) are Default sound in ...(the Realtek microphone), and Windows Record Mixer.
Click the down arrow for the top window and you now see that Microphone (Screaming Bee Audio) has been added to the choices.
Select this option
You can check the levels and effect again before you start
When you are ready, run the film and narrate.
Now when you record, VP will take the output from MorphVOX and produce a sound file that appears in the media window and also placed on the audio track, that has the characteristics you have set with MorphVOX.
Note however that the voice change is not immediate as the program has to create the changes you have set up. This means that precise matching of your narration to the film may be slightly out of synch due to the delay. This is not big deal though as if you narrate against the video accurately the sound clip produced can be moved slightly to match the visuals.
