web radio for Online Lectures.
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.
Just plug your microphones or your recording device in an IQOYA X/Link.
Tell your students via eMail or Social Media to tune in the web radio stream.
Start or Play your lectures!
