Application to stream the microphone

Postby parmi » Thu Apr 16, 2020 12:19 pm

I am looking an application for a piano teacher. He has to give piano lessons to one student at a time. Currently he does video lessons using the Zoom application, but the Zoom application transmits audio only at 32 kHz (sometimes it drops to 24 kHz), moreover Zoom was created to transmit mainly the human voice not a piano, in fact it has different audio filters to suppress background noise, echo cancellation etc. which cannot be deactivated.

After much research I found the VoiceMeeter application, VoiceMeeter allows to transmit at up to 96 kHz (but more than enough 44.1 kHz), PCM 16/24 bits (16 bits is enough) and with stereo mode (must transmit two microphones) without any audio filter.

The only problem with VoiceMeeter is that it is too complicated to do the connection between student and teacher, both must open UDP ports in their routers/firewalls. If only the teacher does configure the router/firewall it would be perfect, but students often don't have access to these settings.

So is there an application that allows two people to transmit (1 or 2) microphones?

I would use a small mixer and route the output of that into Voicemeeter.

Just a minor point, these can be disabled in the advanced audio options. Unless you're saying that these are DFA switches and the filters are still in place?

I have already disabled all the filters in the advanced audio options, but the audio transmission always remains at 32 kHz (sometimes it drops to 24 kHz), but the main problem is that some filters still remain in place.
I made a Zoom recording (with two Rode NT5 microphones connected to the Scarlett 2i2 sound card):

the sound is completely different from the original, also at 0:15 seconds the volume goes down

Recorded with Ableton (44100 kHz 16 bits):

I have not read it yet but surely the May issue is all over this?

I've started using listento. It is a standard plug in that goes on most daws. Sounds very good. In my case, my friend has it on the master bus of cubase. He sends me a link and I stream it. Works really well
