Indiegogo referral program

Refer friends and win aëdle gifts

 

Hello everyone,

 

We decided to offer a special referral program to our backers during the pre-order campaign on Indiegogo. Now, you can refer friends and people within your network to win aëdle gifts for each contribution you bring.

Please find a quick guide below. We are available if you have any question!

All the best,
Baptiste

 

 

What happens once one of your referred friends purchase a VK-X?

You win 1 point, and your friend wins 1 point too.

 

What can I win with 1 point?

With 1 point, you can claim one of the four aëdle gifts valued 1 point (see list below!). You can also save that point and try to refer other friends to claim bigger aëdle gifts.

 

How to participate?

Take part in the referral program is easy:

1) Log in / Sign up Indiegogo

2) Copy  your personal invitation link (to do this, click on this icon located top right on the campaign page)

3) Send the link to your friends

4) If one of your friends purchase the VK-X, it counts like a referral. You both won 1 point!

You can then track your results this way.

 

What are the aëdle gifts?

You can find below all the gifts that could be claimed with the referral program, along with the required points. More info about our products is also available on our website!

 


 

BLUETOOTH AUDIO STREAMING

Part 1 – Why Bluetooth 4.2 over 5.0?

Hi everyone,

We have received an overwhelming number of responses concerning the VK-X and I would like to personally thank you for your support and commitment to our project.

Today I am going to the take the time to respond to a question that has come in a number of emails.

 

Will the VK-X have Bluetooth 5.0?

 

The answer is NO for several reasons. It will, in fact, be 4.2 and it will indeed have the same efficiency of that of 5.0 Bluetooth (that is to say compatible with Bluetooth 5 devices for audio streaming), but I am going to take the time now to explain why we made this choice.

When the Bluetooth Special Interest Group (SIG) announced the creation of Bluetooth 5.0 in 2016, there was a lot of buzz generated for this seemingly major advance in wireless technology. What is interesting, however, is to see at what point certain parties including media outlets and invested companies have questionably manipulated this information for their benefit.

Here are the ‘ameliorations’ proposed by Bluetooth 5 technology that you see everywhere:

  • Range x4
  • Throughput x2

 

What we don’t see or what is not often stated is that, firstly, one must choose between the two ameliorations. It is one or the other in relation to the radio chosen by the system integrator (“PHY”). On the other hand, these ameliorations are exclusively for BT LE (Low energy products), which is technology dedicated to the internet of things with a very low energy consumption. The Bluetooth low energy sends small packets of information and isn’t really adapted to continuous music streaming.

Bluetooth Classic is the technology used for audio applications, via a superieur bandwidth (3 Mbps in theoretically 2.1 Mbps actually) and a profile dedicated to audio applications “A2DP” (Advanced Audio Distribution Profile)

 

In all fairness, to do justice to the BT 5.0, Bluetooth 5 nevertheless sets a very solid foundation for the arrival of a new standard of audio streaming, with reduced energy consumption, to achieve a theoretical bit rate of 2 Mbps, effective around 1.4 Mbps.

Nevertheless, there are several problems to be resolved, via the creation of a new profile (like the profile A2DP used for audio streaming):

  • Recomposition of segmented data packets
  • Management of asynchronous data packets

 

 

To resume,

 

  • Audio streaming via Bluetooth is done via the A2DP profile, managed uniquely by Bluetooth Classic
  • The bandwidth of Classic Bluetooth is higher than the bandwidth of Bluetooth LE (5.0).
  • BT LE 5.0 is a preparation for the future of audio streaming that consumes less energy and yet uses enough bandwidth for high-quality audio streaming

 

 

In my next article about this topic, I will develop more. I will explain more about Audio Formats, Codecs and Bits. Please do not hesitate to post your questions: I will be happy to answer!
