there are the streamin~/out~ objects in both the zexy and
ggee(xt) xtrnls ...
i had to use them at this last performance because i couldnt get the
soundcards on two compaq pc's to work, so i had to stream their output to my
laptop, mix and dac~-output it there.
the streamin~ from zexy was disabled thou .. in version 0.5 (+?) ..
anyhow, it basically worked although the streamin~ has got a few bugs, mainly
that it gets confsued what its actually receiving ..
i was streaming 4 channels (2 from each pc) to the main receiver, but all which
would arrive there were 3 channels max in whatever order i made the 'connect's
also, streamin~ likes to receive 'any' local signal ..
i.e. you put an 'osc~ 220' somewhere, DONT connect it to dac~, then place
a streamin~, connect it to dac~ and the sinewave should be there ..
i can see if/how its reproducible, but i ve had it a few times ..
so as soon as you manage to set up a tcp network over usb/firewire/ethernetz
this should work ..
| i'm aiming to connect two pcs via medium/wide-band ports (like SCSI,
| USB, FireWire or Ethernet) to transmit real-time streaming audio from one pc to
| another, maybe from a sythesis-dedicated (running commercial and
| experimental software) to a hdr one (running typical hdr software). This could
| be easily achieved with common digital I/O soundcards, but *i
| think* there are many reason not for use them: they're too
| expensive , there may occur degradation (esp. if somebody tends to
| save money... ;), and it sounds me a kind of nonsense encoding a digital
| stream into a digital audio signal to encode it back again.
| i think of a "virtual device" that could be seen as a
| normal audio in/out from every application running under Windows,
| better if direct-x based.
| Is it possible to achieve that with pd objects?
| have you got any suggestion, or references?
