I have imported audio-files (.wav) into Sounds, added an Audio object to my layout, and created an event that plays a sound when the player character is jumping.
However... the playback of the sample/sound sounds really lowpitched and with some kind of delay/reverb effect applied. The original sound sounds nothing like it (it's the jump sample from Super Mario, intended to use as a placeholder only, just trying to learn using Construct 3, it's my 2nd day in).
I thought perhaps the playback rate was weird (for this sample) by default, so I added an action (set playback rate) that is performed before the play sound. Changed the rate to 2 instead of 1. Still sounds weird, sounds like the sound is stretched, followed by a tail of the correct sound.
Not sure if there is a decoding/conversion problem here?
Here's a video demonstrating the differences in sound:
