What is the best video call platform to exchange heartbeat live

The other day, I was listening to someone heart over Google Meet. I found that the live sounds was very weak, compared to a local recording my patient sent me. It happens that Meet is touting a voice enhancement feature which eliminates noise.

What is your experience with different video call platforms (Meet, Skype, Team, Zoom...??) to get the best HB sound quality?

Sorry! I had never heard that a heartbeat could be heard through a video calling platform. Could you teach us how to hear these heartbeats through video calling? The Skype platform here in my country has been banned and no longer exists.

I have had good results during Telegram steth sessions

I found that Google Meet has a builtin noise cancellation system which suppressed very effectively any heart and lung sound.

On the other hand, I had very good results listening to someone over Microsoft Teams.
