After resolving the problems encountered with OPPO, the company that represented everything in mobile telephony announced that it had achieved the first video and audio call using three-dimensional spatial audio. The result is to allow the caller to hear spatial audio in real time for a unique audio experience.
This year Nokia has resolved very serious clashes, in addition to the one mentioned with OPPO, since it has also reached a final agreement with vivo to resolve the conflict it had with the Chinese company over the licenses it still holds of yesteryear. Now is the time to show the results of technology that will improve the calling experience on mobile phones.
Nokia is now able to make an audio call over the mobile network using the 3GPP Immersive Video and Audio Services (IVAS) Codec. It generated an unprecedented audio experience during the call in what is called spatial or three-dimensional surround sound.

The edge
The IVAS codec It is part of the 5G Advanced network, an imminent upgrade to 5G mobile networks that could finally deliver faster speeds, power efficiency improvements, more precise network positioning, and much more. In fact, all calls currently made are done on a monophonic mobile network: the audio is compressed on a single channel.
Spatial audio in voice call manages to generate a single sensation so that sound seems to come from different directions by being supplied through different channels. Better yet, the vast majority of mobile phones, provided they have at least two microphones, could enable spatial audio during calls with the IVAS codec.

In this way, the same sound experience could be imitated from applications such as Apple Music or Netflix which already offer spatial sound, although only supported by certain listening devices. The only thing left to make it the norm, Nokia President Jenni Lukander told Reuters via The edgeit’s that operators, chip and mobile phone manufacturers will start implementing it in your products and devices.
It’s not the only one working on the introduction of the IVAS codec in the renewed 5G Advanced mobile network, but it seems that we will have to wait a few more years until mobile phones are capable of generating this type of audio when a user uses it for a voice call.
