I created a project, and imported audio, MIDI, and video. The audio I imported was a WAV file. Is there an ideal format of audio that I should be using, like mp3? I'm asking because when the WAV was playing within the app, it sounded perfectly fine, but when I exported the project into an mp4, there was strange sound distortion scattered throughout. If there isn't an ideal audio file format that should be used, I'll post again with a more detailed description of the issue. TIA.
