Cannot send Audio files on WhatsApp

Question

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



enter image description here




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

Answer

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.
