Hi all,
Sorry to disturb again, but I have a question about DSPMod.
In racer, the sound part is now eating a lot of cycles.
According to hatari, the 68030 -> DSP transfers for the sounds are taking nearly one VBL that I'd like to reduce (the game would run more swoothy).
All my samples are taking 51 Ko in memory.
I'd like to have them in the DSP memory instead of the 68030 memory.
I'd like to start or stop one sound by just sending 1 order to the DSP.
Something like:
move.b #sound_index,(a5)+ ; the sound to start/stop (from 0 to 16)
move.b #start_stop,(a5)+ ; the start (1) or stop (0) command
move.b #loop_mode,(a5)+ ; the loop (1) or don't loop (0) command
move.w #sound_frequency,(a5)+ ;the frequency
move.w #volume,(a5)+ ; the volume
Maybe there's a need for more variables, but this would avoid to send all the sounds data to the DSP all the time, but only the module datas.
Do you think it would be easy to implement ?
Of course, this would be useful to other Falcon game developers ;)
Is there a repository with the source code of the latest DSPMod 3.4 that could be used to implement this ?
I've got older sources, but not the official 3.4 version.
Does anybody here would like to add this feature to the player (if not, I can have a look at it, but I'm not an expert in mod players).
Regards
Laurent

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
