I can't get my audio to be lagless. Tried everything I could

Hi,

I tried everything, and I can't seem to figure out the problem with why is my audio lagging.

The audio needs to be played in the same moment when the player destroys a particular object.
Here is the code that does this:

Code (CSharp):

1. void OnTriggerEnter2D(Collider2D col)
2.         {
3.            string tag = col.gameObject.tag;
4.            //this plays the audio, will get into it as well
5.            AudioManager.Instance.SoundFx(tag);
6.            //This destroys the gameObject, so SoundFX() is called before it
7.            OnHitResponse(col.gameObject);
8.          }

Now, lets take a look inside AudioManager.SoundFx method:

Code (CSharp):

1. public void SoundFx(string tag)
2.         {
3.             switch(tag)
4.             {
5.                 case "Normal":
6.                 case "Hard":
7.                 case "Transparent":
8.                     LadderPlay(hitsQTY, tag);
9.                     //I am recording hits Quantity to know which note to play
10.                     hitsQTY++;
11.                     break;
12.                 case "NotDisappear":
13.                     PlayOneShot(notDisappear);
14.                     break;
15.                 case "PortalA":
16.                 case "PortalB":
17.                     PlayOneShot(portal);
18.                     break;
19.                 case "Death":
20.                     PlayOneShot(death);
21.                     break;
22.             }
23.         }

And here is the LadderPlay method, part of AudioManager class:

Code (CSharp):

1. public void LadderPlay(int k, string tag)
2.         {
3.             // Both triangle and harp sounds will be played with ladder effect
4.             string type = (tag.Equals("Transparent")) ? "Triangle" : "Harp";
5.             // Directory that holds the Triangle and Harp sound effects
6.             AudioClip[] currentDict = audioDict[type];
7.             if (PlayerPrefsX.GetBool(Constants.PrefsIsSoundOn))
8.             {
9.                 if (k > currentDict.Length - 1)
10.                     k = currentDict.Length - 1;
11.                 audioSource.PlayOneShot(currentDict[k], sfxVolume);
12.             }
13.         }

That's the whole code that is called when the audio needs to be played.

Now please, let me tell you all I've tried so far:

1. I used profiler to determine that 'OnHitResponse' (called after the AudioManager.SoundFX() method), is making my game fall to 30 FPS. I fixed that, without fixing the audio lag (but hey, my game now runs smoothly on 100fps, no matter when).
2. I noticed I have .mp3 files, so I changed that immediately, re-creating the sounds in .wav format.
3. I changed the AudioSettings lag settings to - Best Latency (this made my sound FX to have some white noises while playing them, and it seemed that the lag has gone. But when I tried the game on my Android, the lag returned, and the white noise DISAPPEARED.
4. I triple checked that the sound waves in the FX files start from t0 (first second).

Any ideas guys and gals?

I am stuck on this for a week, and I fear that the solution will be something really simple.
Thanks a lot for your time, it will save mine significantly.

 

I did it!!!!

AudioSource.PlayOneShot was causing the problem, it's a less efficient way to play audio.
So instead of:

Code (CSharp):

1. audioSource.PlayOneShot(wantedClip);

I did this:

Code (CSharp):

1. audioSource.clip = wantedClip;
2. audioSource.Play();
