Cannot send Audio files on WhatsApp I just recorded an audio using an app on my phone, The audio file has an extension .WAV, but when I try sending it via WhatsApp, I get this error




  Failed to process audio, please try again later, If you keep seeing this message, please restart your phone


Things I tried so far:

1) I restarted 4 times 

2) Updated Google Play Music and WhatsApp as given in this site 

3) Cleared Data, Cache and restarted WhatsApp

But nothing seems to solve the problem

I have enough memory on the phone, I can successfully send instant voice messages, PDFs, pictures and videos and contacts, I have read that WhatsApp supports .WAV so I dont think its a problem with the audio format, the audio plays well in my phone, so the audio file isnt corrupt or anything,
I have a strong Internet connection too.

Surprisingly I did not find any info on this particular error on the internet, It would be great If someone could tell me what the problem is.

Phone Details: 

Phone: Xperia L

Android version: 4.2.2 (JellyBean)

WhatsApp version: 2.16.207
WhatsApp (at-least the version 2.16.207 on Android version: 4.2.2 - JellyBean) doesn't seem to support audio files with WAV extension, I tried sending an mp3 and it seems to  work fine

However I found that WhatsApp with a same version on Andriod 6.0.1 (Marshmallow) has no problems in sending WAV files

In any case you can always use a WhatsApp File Sender as mentioned in this answer.
