Since the different phasing between the two locations cannot be clearly heard I have tried the following approach in order to make it clearer. For location A I have recorded a marimba note C4 playing in every beat at tempo 120 bpm. For location B I have recorded the same marimba sound but with the note C5 playing in every beat at tempo 120. This way suggests a better approach in showing, and understanding that latency can be added. The ipods were triggered the same time and therefore they were in unison. If changes in latency occur between the two locations then latency would allow the dislocation of beats. During the procedure of documenting this there were many problems like the sound is feeding back from the sound card output to the input, low sound quality and noticable noice. In order to remove all this I use the two accounts of eJamming with the MacBook(White) as location A and MacBook G4( a third laptop) as location B. The output from each location was feed into the sound card of the MacBook Pro that both were recorded using Logic Pro. Moreover, to distinguish the two locations, location A is rooted to the left speaker and location B to the right.
The test above showed that different amount of latency between the two locations could have the phasing effect in the final audible outcome. However using the eJamming software was indeed hard to produce this since the software is built in such a way in order to eliminate latency. The next thing is to test with the same setup is the Ninjam software (http://ninjam.com/) which is an open source/free software doing similar thing with eJamming. However a major difference is that latency is huge in relation with eJamming.
Two things that were not included in this experiment but mentioned in the suggested performance.
1. There are four laptops used, two in each location.
2. Using real pianos there will be microphones that will capture any sound. Thus a feedback effect will be present.
What is next?
1. Try the same setup with Ninjam
2. Use four laptops (two accounts in ejamming and two in Ninjam)
3. Use microphones if possible.
