prelim results from streaming

Yes - its an excellent facility to have "out there" and' in here", complementing the diegesis (or virtual diegesis).

The commercially available technology is not yet reliable to allow a three way relationship but by means of delaying live output to speakers we can get close with opnly 2 of the stratas:
over there and in here. I used nicecast as my server

Results from streaming tests
Software : delay (secs) : reliability of sync
itunes radio : 0.2 : 0-0.01
fstream : 0.23 : -1 – +1.5 secs
Flycast : x
Shoutcast Radio : x
Streamitall : 8 : +-5 secs
iPhone Safari (LAN) : 0.56 : +-0.1 secs [but not pause the stream but the playback]
iPhone Safari (Internet) : 0.62 : +-0.1 secs [but not pause the stream but the playback]

REFLECTION
- For ease of participant engagement I will use the Safari LAN option as this avoids download app issues and might work with blueberry devices or other smart phones too. TO BE TESTED
- The Safari option delay is huge compared to fstream but the reliability and ease of use is better
- The delay is compensated for by delaying the output to speakers in MAX - have to test using many devices and distances TO BE TESTED
- Have not found a reliable way of syncing the 2 audio streams (live and iphone) making the 2nd strata - "out there and in here" - difficult to achieve... shame because it works really well.
