Sound crackling

[rayabusa]

Sound is crackling on a lot of games, maybe a sync issue

[askotx]

Check your settings and give more info.

[rayabusa]

my settings are:

original resolution 240p via component
4:3 default
video mode automatic (NTSC)
super FX default
classic pro controller

the crackling are more frequent when playing rom hacks or translated roms but happens with normal games too.

It is the same problem I am having, actually my issue is just below yours :P and this is also using 4.3.7 version of the emu, and your exact same settings.

One thing to note is that this does NOT happen in let's say Snes9x on RetroarchWii. The problem is that Snes9x Retroarch Wii is very slow! Super FX games dont work fullspeed at all in there.

This emulator is so good and fast, that is honestly a shame that this problem keeps ocurring.

Here's a beta, maybe it's better?
Snes9xGX-4.3.8-Beta2.zip

[Nashismo]

Thank you dborth, I will try this beta version right away. The version bladeoner uploaded had the same issues (actually it was less stable than 4.3.7) so I will try yours and will update on how it worked!

Thanks dborth!

[Nashismo]

Tested it. Mostly on Chrono Trigger (the game were the issue is more easy to recreate).

And yes, it is better, much less of that garble crackling sound, but instead we have the audio skipping forward, is like it goes fast forward in order to stay in sync, it is a different issue, but I believe it is better than the audio noise.

It is a step in the right direction I think. Thanks dborth.

Snes9xGX-4.3.8-Beta4.zip

Thanks for testing. Here's another beta. Hopefully this is at least as good as the last if not better. Let me know.

[Nashismo]

I tested Beta3, many roms hang. Tested Beta4, it works correctly. In beta4 the music instead of going forward it seems to stop every now and then and there is a bit of crackling.

Beta2 was good in the sense that it had the smoother sound, with its own specific issues though. Sorry I took longer to test it, I just sold my PC, this from a tablet.

Thank you for you time dborth!

[dborth]

What game did you hear the crackling on? Can you post a snapshot here I can resume from so I can look at it?

[Nashismo]

Like always, Chrono Trigger (US) beginning of the game and when entering in and out of menus (anywhere in the game). That's when the music always tends to stutter or when any given audio issue occur.

I always use that game to test audio on snes emulators :)

The same game on Retroarch Wii snes9x runs flaelessly. It is a shame really, because like I said before this port is really fast! (Maybe thats the problem?)

Cheers and thanks againg dborth

Snes9xGX-4.3.8-Beta5-156-core.zip
Snes9xGX-4.3.8-Beta6-hybrid-core.zip

Here's two more betas.

[Nashismo]

Beta6 Hybrid, that did it! Cant believe it! No more stuttering music or sounds!

I played the game over and over because I couldnt believe it at first. But yes, it is working pretty nice :)

Only thing I notice is a higher pitched sound (bad lows mostly). But that could probably be fixed with an equalizer option in the future! ;)

Or maybe the real Snes had bad lows and the emu is just being accurate? Maybe.

Again. Dborth you are the man! You made me feel really happy with this and I am sure many people will be super glad too!

Cheers from Chile friend!

[Nashismo]

Celebrated too soon. I compared to snes9x on Retroarch and when comparing, Snes9x Beta6 had clear sound distortion and higher pitch sound. You can notice this when the bells ring (sound distortion) at the beginning of Chrono Trigger or high pitch sound (fireworks at the beginning of Chrono Trigger too) the Retroarch version sounds a lot more punchy, with lower sound and no distortions.

Still those issues could be fixed in the future with a sound menu, but they are definetely there. But sound stuttering is gone! 100% sure of that! :)

[dborth]

Was this sound distortion present on 4.3.7 too? I adjusted the playback rate so perhaps that's the cause.

[Nashismo]

Tested 4.3.7 to have a clear memory. And no, no sound distortion in 4.3.7 still the lows arent great but there is no sound distortion at all in 4.3.7. But the audio crackle is back :) in 4.3.7 obviously.

Tested Beta5 (hadnt test it before) and it seems the same as beta6 at least for me. I prefer Beta5 though seems to have a lower pitched sound, but that may just be placebo :p

Im still happy to have music and sound without the stutters/crackling though. Thanks again dborth.

[dborth]

snes9xgx-beta-156-sound-core.zip

Just curious, is the sound on this beta the same, different, better, worse?

[Nashismo]

Dborth sound is better, no distortion! (Chrono Trigger bells, etc) Better lows, not as punchy as Retroarch snes9x but better than before!

The only problem is that the games hang (black screen) after 5 minutes of playing or so.

I couldnt check for sound crackling because of the hangs, but it was good the minutes I could play. A stable version of this one would be something nice.

Thanks for your time dborth! You are almost there in building the ultimate Snes emulator out there (240p, fx games, good speed, good sound).

Againg thanks for using your time to do this.
