Since Google revoked CDMs for older browsers on October 31, 2024, we observe an elevated level of Widevine DRM license rejected errors. We recommend our customers to observe the client error messages, and if "revoked" errors are encountered, to update users' browsers. With the latest revocation, it requires a Chrome version 117+ to deliver a Widevine license successfully.

Encoding audio

Did you know that with Axinom DRM you can also protect pure audio files?

People usually think, DRM (like Widevine/PlayReady/FairPlay) is about video protection. It is correct, but it is NOT ONLY about video. If you have an audio file (say, MP3), you can feed it to Axinom Encoding, which will convert it to MPEG DASH format and encrypt the audio track according to DRM standards. If you provide no video input, there will be no video track in the output DASH manifest.

You can now use all regular video players to play this asset. In UI it makes sense not to display the video area, as there is no video. But the audio track will play. All the same approaches for an entitlement message ("token") acquisition and sending it to a DRM License Service apply.

Try it out yourself.
