Sound Comparison: Phone Calls via Audinate Dante AVIO USB-C vs Bluetooth Adapter

I just did a quick test to see if there is any difference in sound or quality between using an Audindate Dante AVIO USB-C Adapter vs an Audinate Dante AVIO Bluetooth Adapter when recording a phone call.

In the test you can hear that both version do not offer great sound. This might stem from the fact that the headset used is rather mediocre. In my opinion, the Bluetooth adapter has a more metallic sound and is less preferable. See below for more details on both spectra.

The video has a rather long black tail. This was not intended did slip through my quality ensurance programme. Sorry for that.

When looking at the spectrum of both samples, it seems that the USB-C adapter has a *sharper* cut at the upper end. But maybe I am misinterpreting that:

The following two videos show the spectroscope of both recordings (USB-C and Bluetooth):

This is it for today’s post. What are your thoughts about these adapters?

ps By the way, I just tried my first instagram video in “portrait mode” by using this video (still with black on top and bottom). Tell me if this is better viewable than a standard 16:9.

Layout of Portable Audio and Video Setup

A couple of weeks ago I posted a video of our portable audio and video setup:

Building a portable web conferencing audio and video setup with a Sound Devices 833 and Dante

In the video I did not show you the actual diagram of all the wiring. So here it is:

Setup with analogue adapters running out of 833

This is actually a modified version as I since replaced the Audinate AVIO Dante AES adapter with an Audinate AVIO Dante Analogue Input adapter. If you are interested in the difference of quality and latency between these adapters, check the following image (taken from RX8) or see this video:

AES adapter on top, Analogue adapter on the bottom (slightly higher noise floor and 10 samples behind)

The original layout with the AES adapter is this one:

And in case you are interested, here is the Dante configuration as seen in the Dante Controller:

Dante Configuration in Dante Controller (with AES)

Replace the AES adapter with an Analogue Input adapter and set the L/R outputs 833 to *Line*. With the analogue adapter we have to use both cables/physical outputs (instead of just using the L output in AES mode). And a side note: there is no output delay possible on the 8-series mixer with AES as the output.

This is it for today. See you next time.

audio and video and everything else

Beginning with the COVID-19 pandemic, at my daytime job I suddenly had to switch from face-to-face meetings to *virtual events*. Therefore I reactivated my analogue radio station knowledge from the nineties and invested in some audio and video gear. As it became apparent very quickly, technology had advanced in these 25+ years with things being possible I would not have imagined.

In the last 12 months I spent some time trying out mixers, software and ways to connect stuff. In that time, I learned quite a lot from others and hopefully I can pass along some things I came across on my way. So from time to time I will post a video on YouTube, Facebook, Instagram or Twitter and write about my findings. And with that being said, the contents of the Twitter channel (being dormant now for a couple of years) will definitely change.

See you around. Ronald
