How to Add Audio
The current version of Letters in Motion supports MP3 audio files. Any other audio file will result in a loading failure. We hope to get an update out soon that will allow for more flexibility. Until then, there are a few free tools on the web that can quickly convert other audio files to MP3 versions.
Next, store the MP3 in the Letters in Motion folder. The Letters in Motion file is located on your device and is also where your rendered video will be stored along with all of your additional media like images and audio. On Android devices, it is easy to locate the file using a file management app then simply copying media into it (learn more). For iOS devices, the process is a little more involved. Follow the same steps suggested for finding your rendered video.
Once the audio file is in the Letters in Motion folder, you're ready to assign the audio to the project. Open your desired project in Letters in Motion and tap Menu.
Within the Menu, open Project and select Audio. From here you can Browse the Letters in Motion file for your desired audio. Once a file has been selected, it will be listed at the top of the Audio Settings screen.
Your audio is now attached to your project although it does not appear as a separate track. You can test this by scrubbing through the project (make sure the Audio option is On).
Once your audio has been added, you can easily match your animations to sound to create a fun and impactful video.
