WhatsApp brings a novelty that can save us from many errors or confusion when we send voice messages. With update 2.21.170.15 (which WhatsApp is partially enabling for certain beta testers), before sending an audio, you will be able to listen to them.
As the video published by WABetaInfo on its Instagram profile shows, when you have just recorded the audio, in blocking mode (that is, on the microphone, when you are recording, if you upload you can continue recording without pressing any button), you have a button with a square inside a circle, which translates as pause in recording programs.
Therefore, you can click on this button and listen to your audio. You can even listen to the audio from the point you select (just like when you hear a voice message already sent). If you like the result, you can simply send it and, if not, you can click on the trash icon and re-record another message.
WHATSAPP Tips and Tricks to HIDE YOURSELF TO THE MAXIMUM AND MAINTAIN YOUR PRIVACY
There are already tricks to listen to audios that are not from WhatsApp
It should be remembered that there is a trick to listening to voice messages before sending them, but it has some complexity. There is no native way to listen to voice memos before sending them, but that seems to be close to changing.
Considering that this now native feature is already available to beta users on iOS and Android, it is expected that it can reach the stable release soon. This same new functions have been known that could soon come to WhatsApp: On the one hand, the company is working on adding reactions to messages, similar to those we have on Facebook, Messenger, Instagram, iMessage, or even on Twitter direct messages.
In addition, it has been known that the firm is testing the option that you send money within the same app how can it be done with Bizum. On the other hand, for almost a year there has been talk that WhatsApp wants to offer multi-device support.
A few weeks ago, the multi-device feature appeared in the beta version. But it was incompatible with Android-based and iOS-based tablets (iPad). The new version of WhattsApp, still in beta mode, it can already work with Apple iPads.
