So I am now trying to find sounds for my guns but when I grab a gun sound effect and play it in my game a lot of the sounds are either terrible sounding or have this horrible echoing effect because as a gun shoots sometimes the previous sound is playing still.

public void shoot(float x, float y, float direction){

    if(empty){
        PlayHUD.message = "No more bullets!";
        return;
    }

    if(reloading){
        return;
    }

    if(System.currentTimeMillis() - lastShot < fireRate){
        //AssetsLoader.lmgSound.stop();
        return;
    }

    float dx = (float) (-13 * Math.cos(direction) + 75 * Math.sin(direction));
    float dy = (float) (-14 * -Math.sin(direction) + 75 * Math.cos(direction));

    float dx1 = (float) (-13 * Math.cos(direction) + 75 * Math.sin(direction));
    float dy1 = (float) (-14 * -Math.sin(direction) + 75 * Math.cos(direction));

    PlayState.effects.add(new MuzzleFlashEffect(x + dx1, y + dy1, (float) Math.toDegrees(-direction)));

    PlayState.projectiles.add(new Bullet(this, x + dx, y + dy, (float) (direction + (Math.toRadians(MathUtils.random(-accuracy, accuracy))))));

    if(OptionState.soundOn){
        AssetsLoader.lmgSound.play(OptionState.volume);
    }

    bulletsInClip--;
    lastShot = System.currentTimeMillis();

}

Here is the code for where the sound plays. Every time this method is called the sound is called but it happens so often in this case that there is this terrible echoing. Any idea on how to fix this?
