Snapchat is well-known for releasing features to help creators with content creation. It has announced a couple of new features named Sounds Recommendations for Lenses and Sounds Sync for Camera Roll. Both these features are meant to help creators add the best-suited sounds for their content.
The feature Sound Recommendations for Lenses is all about suggesting relevant sounds for Lens filters. A user needs to choose their preferred Lens for photo/video and then tap on the Sounds icon. It will give users a list of sounds that are relevant to the chosen Lens. These suggested soundtracks will be from the top ones selected by other users.
Sound Sync for Camera Roll is a feature that can automatically sync sound with your photos and videos. It is useful for montage videos where users can add 4 to 20 photos/video clips from the camera roll in a single video. The feature will sync these photos and videos with every beat of the selected audio track.
Both these features are already available in the United States. Snapchat has begun rolling them out globally for Android and iOS users. You should check for the update and download as and when it becomes available for your device.
