Shunyuan's HLE audio plugin v1.0

Edit: Disregard, Killer instinct must have "fixed audio timing" otherwise the audio will be to fast.

Bomberman 64 still has some serious audio issues, hopefully FatCat can look into it.

You actually may not be able to do that, I don't know

Yes, I want to change the thread title for each update and I can't.

But it is fine.

Have you ever had a chance to look at Bomberman 64? No plugin so far has been able to get rid of the sporadic audio skipping. I mean, it if isn't too much trouble to take a gander that is.

Other than that game, the plugin is awesome. Keep it up

Two questions:

(1) I can't get this game boot for both v1.6 and v2.0 even with NoVideo plugin. What are your settings and the plugins that you use?

(2) Did you uncheck both "Fixed Audio Timeing" and "Sync using Audio" game settings if you think the audio timing is too fast?

if you have both setting unchecked, then you will have fixed 60 fps.

If you unchechked the "Fixed Audio Timing" and Keep "Sync using Audio" then my audio plugin will cache audio data as much as possible and return to main CPU immediately. So the frame rate may be higher than 60, just like overclocked.

If the game frame rate drops below 20 or the frame rate is very unstable, no matter what causes it, the audio data will severely underrun. Under this situation, very little can do for audio plugin.

If the slow down caused by graphics rendering is fixed, I guess the audio problem will also disappear at the same time.

There's no slowdown, the framerate is indeed 60 fps, there's just audio skipping every two seconds. This happens on PJ64 1.6 as well.

Here's a wav sample I recorded.

Again, the framerate is full, so no slowdown. If you opened it up in a program like Audacity, you can see the gaps in the spectrogram if you zoom in.

Summary

Full speed
No slowdown
Audio skipping every ~2 seconds

Thanks, your information is very helpful. I am looking my code to figure the bug.

Let me know if you need any more info. If I came across as being demanding or overbearing in that post, I apologize

HLE audio crackles on the sound played when opening a savegame and LLE audio crackles on the sound when opening the menu by pressing the start button. All in all LLE audio crackes less than HLE audio using your plug-in.

To sum it up, Azimers plugin still provides much better quality because it does not crackle in any of these situations.

Also while using your plugin in Banjo Kazooie, the music volume gets turned down when fighting or collecting an item, I never experienced this on a real console. This also happens with Azimers plugin but it is not as obvious there.

I have modified my functions to handle audio data overrun and underrun situation, now Zelda OOT sound crackles should fixed.

I rewrite the code to handle audio data underrun and overrun. Please help me to verify if the new build fixed the audio skipping problem of Bomberman 64.

Thanks.
