Base64 to Audio

Convert Base64 to Audio online using a free decoder tool which allows you to decode Base64 as sound file and play it directly in the browser. In addition, you will receive some basic information about this audio file (duration, MIME type, extension, size). And, of course, you will have a special link to download the audio file to your device. If you are looking for the reverse process, check Audio to Base64.

  • Vinay,
    HI I want it to be converted
  • Riley,
    How are you decoding base64 into ogg? I thought it wasn't possible to decode ogg files from base64 , especially on Google Chrome.
    • Administrator,
      The Base64 algorithm has no restrictions on what kind of data it can encode or decode. If you need to decode OGG files on client-side, you need to use the atob function.

In the meatdata, it says audio/vnd.shazam.sig. On the page, it says audio/octet-stream.
    • Administrator,
      I'm not sure, but I don't think your data is an audio file. Perhaps it is a spectrogram (acoustic fingerprint) and this is why you cannot get the original audio input.

      By the way, your string contains a \u003d which seems to be a Unicode escape sequence and it cannot be part of a Base64 string. So, make sure you are trying to decode the right string.
  • Syberam,
    Hello, I would like to know wich language you used for this tools and if the project is repositoried somewhere.
    I try to decode a base64 string from mp3 with a python (2.7 can't use an other version :( ) piece of code but my file is unreadable after generated with my code, (but with yu tool it is working very well)
