When assigning a character to lip sync a voice recording, the lip movement and the mouth width of the character are determined by the loudness of the recording. The character's lips and mouth will dynamically narrow and widen based on the loudness of the audio playback.
The size of the audio file's wavelengths typically indicate whether or not an audio file will provide expected results.
Low wavelengths:
Normal wavelengths:
If the volume levels of a voice recording are too low, the character's lips may barely open, or open less than the dialog is intended to display. Below are two methods that can be used to adjust the audio file for better lip syncing results.
- Using an audio editing application (Audacity)
- Using speech enhancement (Professional, Agency, and Enterprise users)
Using an audio editing application (Audacity)
Using Audacity, the wavelengths on imported audio files file can be boosted:
1) Open the file in Audacity:
2) Select the entire track:
3) Click Effect, then Amplify:
4) Set the New Peak Amplitude to -3.0:
5) Ensure the recording channel is set to 2 (Stereo):
6) Export the file:
7) Import the file into Vyond.
Note: Adjusting the volume of an audio file in Vyond Studio will not affect lip movements. The adjustment must be completed prior to importing.
Using speech enhancement (Professional, Agency, and Enterprise users)
Within the Audio Settings panel is a toggle for the Speech Enhancer. Activating this toggle will enhance the selected audio file by removing background noise and adjusting audio volume levels to produce a more consistent result. This can drastically improve audio with inconsistent levels, or it can help to amplify lower volume recordings.
1) Right-click on an audio file in the timeline to open a contextual menu.
2) Open Settings.
3) In the Audio Settings panel, toggle on the Speech Enhancer.
4) It will take some time to process the enhancements. When complete, the audio file will display a Powered By Dolby.io tag.
