Hot-loading WAV files

[balmy vale]

I started asking around on the BepInEx discord and they directed me here because this is a core unity concept - i'm trying to hotload wav files to replace audio assets as they play in game - it successfully swaps the soundclip with something else but no audio actually plays.

            var www = UnityWebRequestMultimedia.GetAudioClip(wav, AudioType.WAV);
            www.SendWebRequest();
            var clip = DownloadHandlerAudioClip.GetContent(www);
            
            if (www.result != UnityWebRequest.Result.Success)
            {
                Debug.Log(www.error);
                return true;
            }```

Does the resulting audio clip have the content you expect? The appropriate length for example

The first thing that jumps out is that you're not exactly waiting for the web request to finish, you're just immediately going to grab the data from it

try putting it in a coroutine and doing yield return www.SendWebRequest

[balmy vale]

async might do it

[balmy vale]

the client i'm working with is not for the faint hearted, and i am the faintest of hearts but you raise a good point with a coroutine

alright i'm giving it a test

the original clip is no longer playing but the new audioclip is also not playing

[balmy vale]

okay, did some digging

right side is replacement file, left side is original

this also occurs when using the game's original audio files

Did you correct the loading logic to wait for the request to complete? Async/coroutine?

[balmy vale]

yes

[vapid shore]

It is possible that you must wait for processing of the data after waiting for the request to be done. Then dispose www.

{
    var www = UnityWebRequestMultimedia.GetAudioClip(wav, AudioType.WAV);
    //wait for request
    yield return www.SendWebRequest();

    if (www.result != UnityWebRequest.Result.Success)
    {
        Debug.Log(www.error);
    }
    else
    {
        //wait for post processing content
        while (!www.downloadHandler.isDone)
            yield return null;
        //retrieve result
        var clip = DownloadHandlerAudioClip.GetContent(www);
        //...
    }
    www.Dispose();
}```

10-4

[balmy vale]

oh, disposing is handled if you use a using block

[vapid shore]

Yes, did it help?

[balmy vale]

no, it didn
