Any chance of supporting software-controlled sound volume changes?

Postby Foebane » Sun Jul 24, 2016 4:16 pm

I've used Steem SSE 3.8.1 for a while and I've noticed that there seems to be no means for programs that are running to control the volume of the PCM audio of the Atari STE, so every time a program fades in or out a sample's volume, it just doesn't happen. Older versions of Steem used to be able to do this, but I wonder why this support was removed in SSE?

Also, will there be an opportunity to fix the little clicking noises that happen when PCM samples start and stop playing? I find I cannot fix the problem, and yet, again, it didn't exist in old versions of Steem. Any chance of fixing it yourself?

To report bugs, please use the "support" section, not "development", and be specific so that issues can be reproduced.
Question: did you check option Sound/Microwire?
Remark: current version is 3.8.2.

I didn't have it checked, but tried it just now (running 3.8.2 now, forgot to mention) and it sort of helped a bit, but I wasn't actually sure what the option did.

What about the clicking? It was absent in Steem 3.2 but I don't know what's causing it here. I've tried tinkering with every setting, to no avail. Any advice?

EDIT: Sorry, I'll ask about that properly tomorrow, in Support.

It's in the manual:

-Microwire

STEem being an STE emulator, it was high time we added support for this
rarely used feature of the STE, the ultra-cheap Microwire tone controller.
We use simple 3rd party DSP code by Maverick (Fabio Bizzetti) to add
control over volume, balance, bass & treble in those rare cases.
I'm sure it doesn't exactly sound like on an STE, but I doubt they sounded
that great anyway.
Note: due to some bugs, treble control has been disabled for now.


It's on my TODO list...

Oh, I do beg your pardon, I guess I should RTFM. I have to admit, I never had an STE myself (just STFM) and I wasn't clear on how the enhanced graphics and sound worked with the stock ST hardware, but lately I've been impressed by STE Demoscene productions, and it is these that I'm running mostly on Steem. I didn't even know there were differences between this emulation and real hardware until I saw YouTube videos of real hardware running the demos, and whilst Steem 3.2 plays the sounds more like real hardware, there are too many graphics glitches, especially with overscan stuff, whilst Steem SSE has no graphical glitches that I can see, but audio problems.

I will post some bug reports tomorrow, to see if it's just my config that is at fault or not.

Thanks for the replies!
