Whenever I open an MMF 1.5 game in MMF2, there are some sounds corrupted, because MMF2 adds a disturbing crackling noise at the end of some wavs. Sometimes it even happens when adding a sample to a native MMF2 game. It's definitely not related to my sound hardware/driver.
Any chance this will be fixed?
Is it random?
Does it matter if the compress sounds property is checked or unchecked?
Does it make a difference if all the sounds in the game are the same resolution and format?
Feel free to upload some of the sounds that are causing trouble. I can examine if there's something about the samples themselves that can be misinterpreted by MMF2 (I'm pretty good with audio).
Try deleting the sound actions and re-doing them. For some reason I sometimes get this for no apparent reason (I don't even have MMF 1.5). If I delete the sound action and re-do it that sometimes works.
Thanks for your suggestions!
Game_Master, re-doing doesn't help, because the corrupted sample is stored in MMFs data elements. So it's not a runtime problem, but a general one.
Nifflas, the samples worked for years in the original MMF1.5 app, so MMF2 should accept them, too. Just for info, this one causes the worst problems with 2 cracklings at the end:

But probably you won't notice any problems when opening it in MMF2, see below.
Jeff, only some samples have this problem. When I restart from scratch and open the 1.5 CCA file in MMF2, always the same ones cause trouble again. Samples have different resolutions. Sound compression was deactivated.
Just edited the data elements and replaced the ROAR sound with the original wav - now it seems to work! If I start a new app in MMF2, this sample works fine, too.
Also tried to recreate the problem and made a small test app in MMF 1.5 which played some critical samples in various resolutions. But after opening in MMF2 no problems showed up. Strange...
When I downloaded the sound and tested it in MMF2 Dev, it seemed to work fine. No crackling.
Yes, that's the strange thing, it doesn't seem to be a problem specific to this sample. Seems the conversion from 1.5 to MMF2 has something to do with it.
Wierd...
I think there was a bug with the sound size in old versions of MMF 1.5 (or was it 1.0 / 1.2?), fixed in a patch. Maybe this bug was not revealed in MMF 1.5 but caused a conversion problem with MMF2. That would also explain why you can't reproduce it with the latest build of MMF 1.5.
Ok, thanks for the info, I'll keep this in mind when converting older games. Fortunately I kept the samples of each game separately, not only within the CCA.
Now, after years, I know it made sense ;)
