Sonia performance
Dec 6th, 2005, 8:00pm  
Hi

A couple of questions about the Sonia library.

Does the total number of existing Sample objects, which are NOT playing, affect system performace (I mean do they consume CPU time)?

Apart from lowering the sampling rate (which I already did), is there some other way to increase performance at the expense of sound quality or reliability? For example, I dunnow, some sort of lowering the sound engine priority so that if cpu power is not sufficient for everything sound will be the first thing to be affected?

Maybe I am speaking nonsense... I'm trying to add a very minimal sound to a project which is already quite CPU-intensive; it doesn't have to sound great, just to sound something Wink

Thanks
Teo

Hi Teo,

you can unload samples from jsyn by adding a timer parameter to the stop() command: mySample.stop(10) will unload the sample 10 'ticks' after it is stopped. This helps with optimizing cpu power.

Other than that, the jsyn engine is operating on its own thread, but it is not prioritized. I'll look into this option for future releases. Still, heavy cpu programs will probably degrade both graphics and sound playback.
