Typically, this kind of thing points at issues with the source asset, usually with the format they’re in. MP3 being the source format is a common culprit, for reasons you can read here: [MP3 loops with an audible gap, the equivalent WAV doesn't - #3 by Leah\_FMOD](https://qa.fmod.com/t/mp3-loops-with-an-audible-gap-the-equivalent-wav-doesnt/21931/3)

If your source assets are MP3s, I’d recommend re-rendering or re-encoding to another format like WAV or OGG. If they aren’t, what format are you using?
