The purpose of my future app is to be able to receive data and to render 
it, both in the same app, so I would prefer not to use interprocess 
communication. Indeed, as far as I know, pipes are used to share data 
between two separated apps.(I'm not really aware of these matters, so I 
might be wrong). Moreover, I've read somewhere that this solution would 
be less efficient (for some reason that I'm not aware of).

I'm trying to do this, by modifying the FileSink class (to create an 
BuffSink) and the DeviceSource class (to create my BuffSource). I'll let 
you know if I encounter some problems :)
Thank you for your help and your time,
