Voice messages are the popular means of communication for scenarios that are lengthy or unable to describe via text messages. Now, the voice message box will not be the same as it used to be for a very long period of time.
WhatsApp is altering the way your voice message looks. When you get a voice message from a contact (or if you send one), you are accustomed to seeing a progress bar during playback. Other popular communication apps, such as Instagram and Telegram, have been doing this for a long time.
Basically, it’s a handy visual aid that helps let you know how long a message is and how much more there is to listen to. But now the feature is getting a bit of an upgrade to make it more visually appealing thanks to voice waveforms.
We’ve already seen WhatsApp experimenting with waveforms, with Android users who have joined up for the beta program getting a sneak peek at the functionality. But it was only a tiny glance, since voice waves were quickly deactivated without explanation.
The fact that the new visual accompanying to voice messages is now accessible for iOS and Android beta testers (but only for beta testers) might indicate that the functionality is nearly finished and ready for a broader distribution.

But there isn’t any big deal as it’s just a visual update that can help you in the least possible way is that they are useful visual aids that may be reassuring when there is a period of quiet in a message; if there is no activity in the waveform, you can fairly believe that there is no sound to hear, rather than that your speakers or hearing are malfunctioning.
This new visual feature is being made available to beta testers, it may not be available to all beta testers right away.
According to WABetaInfo, the function is compatible with WhatsApp beta for Android 184.108.40.206 and WhatsApp beta for iOS 220.127.116.11, so make sure you have one of these loaded for the best chance of getting to try out the new feature.
