NAudio - DirectSoundOut in memory even after disposal [Answered]

Hello my friends,

This is my code :

            Stream str = String.IsNullOrEmpty(fromUri) ? getStreamFromKey(e, state) : System.Reflection.Assembly.GetEntryAssembly().GetManifestResourceStream(fromUri)!;

            WaveFileReader wfr = new WaveFileReader(str);
            WaveChannel32 wc = new WaveChannel32(wfr);
            DirectSoundOut wfo = new DirectSoundOut();
            wfo.Init(wc);
            wfo.Play();

            wfo.PlaybackStopped += (sender, e) =>
            {
                wfo.Dispose();
                wc.Dispose();
                wfr.Dispose();
            };

This is the code that make my program laggy after 40-50 seconds (note that this code is repeated 3-4 times each second)
+ After this time the sound become laggy, like saturated for no reason.

Can someone help me fix this code ? I don't know what to do more than "Dispose()"
PS: you can see in the image the object on NAudio that had been created

Thanks 🙂

please 🥺

you didnt dispose the stream?

Are you re-reading the file 3-4 times per second?

I've just done it, it still laggy after a minute

yes because I am doing a keyboard game and everything you press a key it make a short sound

First off, that would hinder performance.
Second, add a method that you can execute when it get's laggy, in that method call Gc.Collect() and see if it makes a difference

Still laggy :/

Maybe there's just a better library to plat audio?

I don't think there's a memory leak in NAudio, can you send a screenshot of the objects after calling Gc.Collect?

I just putted it here

so when it's become laggy I press on escape but nothing change

Oh, I meant a SS of the profiler 😅

a what of the what? 🤠

Oh

I see what you meant sorry

it's just all new

wait i'm doing it

Np

this is before and...

looks like it removed some obejct yes

so the problem isn't here o_o

Okay, where are you disposing the DirectSoundOut?

here, just after the audio finish

PlaybackStopped won't be called because you're using WaveChannel32

oh yeah?

Try using Wave16ToFloatProvider

there is no .Dispose() for this one, is this normal?

Yes, that's okay

it works!!!

no more laggy audio

!!

thanks a lot 😁 😁 😁

The problem with WaveChannel32 is it never stops providing data even after the file's been fully read 😄

I did just copy past the code from the internet because I sucks with NAudio ^^' xD

thanks again I'm happy now c:

Np, make sure to remove Gc.Collect as well 👍

yeah thank you c:
