scheduling accuracy for audio

[andrea valle]

Dear all,

I have created a large Python-based GUI project and I'd like to use it 
as a GUI interface for real time audio sequencing (using the 
SuperCollider -SC- synthesis server).
Python (the client) and SC (the server) can communicate via OSC 
protocol (there are available implementations). SC will generate events 
responding to Python messages.

In order to have sequencing I have to send at precise timing messages 
from Python to SC. Obviously, being a musical application, I need 
millisecond time accuracy, with less latency as possible or at least a 
fixed (short) latency. More, I need to have multithreading, with many 
processes sending messages from Python to SC.

I know that I can create a similar architecture in Python with sched 
and time modules, using scheduler class and .sleep method. But I was 
wondering: how precise will be timing?
Is .sleep suitable for audio/music.


Any hints?

Thanks a lot

Best
