Streaming with IQOYA – Fixing the common problem

Usually, a software streaming solution, like Zoom conferences, Skype or Messenger calls produce unreliable audio signals with distortions, ringing or even dropouts.
An unsatisfying solution for high-quality online education.

By replacing the software connection with a Broadcast-approved Digigram IQOYA hardware, with built-in FLUID IP streaming technology, the streaming quality over unreliable networks, like the internet, is simply amazing.
Finally: A perfect audio signal, no issues at all!

Empty. Not vacant.
