Sound sounds weird


I have a problem with the sounds in game maker. I've recorded sounds in wav and mp3 format, and try to use them in game maker like this.

if !audio_is_playing(sound1)
audio_play_sound(sound1, 10, false)

But it just sounds weird, and not at all like how it sounds when i play from game maker outside of the runner. It's a noticeable difference from most sounds i play in game maker, while other sounds do not sound much differently when in runner. Is it because of how sounds are compressed in game maker, or could I have done something wrong?
