Hello I made it so that when the player shoots the audio loops but i have noticed that unity autmatically makes the audio fade in and out i dont want this for seamless looping what to do ?

What unity version?
On what object do you have the audio source?
Can you send your code?
Very sure the audio isn’t faded to begin with?

Unity version 2021.3.5f1
my code is

 gunsound.clip = shot;
        if (gunsound.isPlaying == false)
        {
            gunsound.loop = true;
            gunsound.time = .5f;
            gunsound.Play();
        }

this is isnt the entire one but the one related to the question i tried trim but barely makes a difference and yes i opened it many audio softwares no fade in or out except after importing to unity also i tried time its kinda works but i wanted to know how to remove the fade without using time
