Last week, the WhatsApp API has started returning an error message for the voice notes, Unsupported Audio mime type audio/opus. Please use one of audio/ogg; codecs=opus, audio/mpeg, audio/amr, audio/mp4, audio/aac. This error began appearing on May 1. Even though there was no change in the files and content type, FB API started rejecting the file.
In this PR, we are converting the audio recordings from Wav to Mp3 from frontend itself.
