the messaging service WhatsApp is currently testing a new type of interface for audio messages, which applies wavelengths and allows the recipient to know more about what he is about to hear, according to what was revealed by BetaInfo.
As revealed, the new interface is available in beta 2.21.240.18 of the iOS version of WhatsApp, so it is only available to a very limited number of users. It should also be noted that, at the moment, in order to see this interface, both the sender and the recipient must have access to this beta.

From what was also revealed, coming from several insiders, this new interface was already being tested by WhatsApp for some time, so it is highly likely that it will be available globally for users of the application.
