How to convert base64 string into an audio mp3 file?

Question

I'm getting a base64 string from android side. I have to convert it into an audio file and have to save it into a folder. I thought I have to convert it first into byte array. Then after it, I have to convert it into a mp3 file. But don't know how. I have done work in base64 to image. If anyone know answer then please explain with an example. Thank You.

What data is in the base64 string? Voice or random garbage? If there is a ready-made mp3, say encoded on client side, then process as if it would be a byte sequence, aka base64decode and save to disk. If there's something else, I say make client work instead of doing all this on the server. — Vesper, Jun 01 '15 at 11:32

If the base64 encoded data already represents an MP3 file, it should be as easy as decoding the base64 data and storing it in a file:

file_put_contents('audio.mp3', base64_decode($data));

And the reverse is as easy as `echo base64_encode( file_get_contents( 'audio.mp3' ) );` – Fabien Snauwaert Feb 25 '17 at 10:40
