How to create an audio file from a mp3 base64 string

"Convert a base64" from an "audio" to a file with "Javascript" and Cordova is more easier than you think. However, you can't directly use the cordova-plugin-file to write your string into a file because it is not supported. However, the filewriter accepts binary data, so taking advantage of this principle that's the way in which we are going to save our string as an audio file on the device. To create a mp3 file from a base64 string, we'll convert it into a Blob using a non-conventional method.

As we are handling files, you need to have the cordova-file-plugin in your project. To install this plugin execute the following command on your command prompt

How to "Base64" and save a "binary audio file" to

First we need an audio file

I don't want to point to any specific audio example since I'd feel bad if some poor soul's hosted mp3 file gets hammered (not likely) because of this example. But you just need a link to a simple, short mp3 (or whatever audio type you're trying to test). If you look at the sample below replace <> with the link to your test audio file.

Won't fit in localStorage?

If you're trying to save an audio file that's too large as a Base64 encoded audio file will be larger than it's original size and we don't get very much space in localStorage then, ya you're using a file that's too large Get something smaller or don't to this. Just sayin :P

How does it work?

Use fetch api we can easily get at the blob()

Run the Blob through the FileReader

Which also handily turned it into a data url for us

The data url is just a base64 encoded string which is easy to save to localStorage

Read the string back out of localStorage

Set the audio's src attribute to the audio data url


While I was prototyping this I was borrowing someone else short mp3 file and to work around CORS (cross origin http request) I used the handy<> service. This may be ok to do for a prototype, but you should't typically run your requests through this service. It's insecure and against pretty much all the different web religions.
