Sounds like it has been converted to low quality.
-First of all, make sure you are importing a wave file that is 16 bits/44.1KHZ or 24bits/48KHZ (you might already be doing that). I could imagine if you import some other format that wav, that things can get screwed in the import.
-Then check the quality settings on the imported wave file (not audio cue). Set it to the best quality and listen again.
Ya, that’s definitely not intended behavior. Is it doing this with all sounds you import?
If the Sound Class / Base Submix / Attenuation on your asset isn’t blank, I’d check if those have any effects or modified filter cutoffs on them. (Though those are normally all blank by default, so its unusual for things like that to cause a problem on import).
Otherwise, sometimes things like this can happen if there’s a large discrepancy between the original wave file’s sample rate and the platform’s sample rate. Might be worth looking at your platform-specific audio settings to verify if anything odd with sample rate/compression/resampling is happening there.
