On August 20 2020, from our homes, the auxiliary advisor Federico López presented an idea of research about low latency streaming for musical ensembles and other sound related live performance, with or without a PA operator. Previously, we found three applications for start the test: reading the respective factors of each one of them previously. The software selected were Sagora, JamKazam and JamTaba.
These are the particularities, one by one:
1. Sagora: is a free software created by a group conformed by researchers and educators of EUDA-UNQ here in Argentina. Its main objective is to offer a possibility of live performances for the musicians playing in virtual rooms from his houses. The 48 kHz function is the highlight here, sacrificing the audio quality in order to obtain time compensation, with a result more approximate to real time. We deduce from this that a more elevated sample rate starts to benefice the latency problem.
2. JamKazam: is also free software to play live music in sync with others from different locations. The app sacrifice the audio quality for benefice the latency problem, but the delay is too long to considerate the system like in real time, being unable of using a metronome to sync with other participants.
3. JamTaba: Uses ninjam servers to provide permanent jam sessions whit people all around the world. The software prioritizes the audio quality by generating a latency of up to 30 seconds being compensated with a metronome to sync, with 7 participants in the virtual room. It isn't for live streaming music.
Preliminary conclusion: we deduce that the best platform of transmission of data on line is Sagora in comparison with the others. Perhaps it's for having local servers that allow a more fluid point-to-point connections and the support of 48 KHz buffering.
