Node.js - Can't play .wav audio file converted from base64
0
By referring the following link here, I have converted base64 to .wav audio file. But it's not playing in any application except VLC media player.
Can anyone provide me the solution for this.
Client side code:
const audioBlob = new Blob(this.audioChunks, { 'type': 'audio/wav' });
var reader = new FileReader();
reader.readAsDataURL(audioBlob);
reader.onloadend = function() {
var base64data = reader.result;
resolve(base64data);
}
Server side code:
var fs=require('fs')
//Here base[1] is my base64 data
fs.writeFileSync(filename, Buffer.from(base[1].replace('data:audio/ogg; codecs=opus;base64,', ''), 'base64'));
Thanks in advance!

You say you're writing a WAV file, but the metadata suggests it's an OGG file.

Even I tried with the following statement, fs.writeFileSync(filename, Buffer.from(base[1].replace('data:audio/wav; codecs=pcm;base64,', ''), 'base64'));

You should check whatbase[1]actually starts with.

"data:audio/wav; codecs=pcm;base64,GkXfo59ChoEBQveBAULygQRC84EIQoKEd2VibUKHgQRChYECGFOA......" . This is how base[1] value starts with, if I use data:audio/wav
