Voice Obfuscation #616

Open KeeJef opened 4 years ago

KeeJef commented 4 years ago

When sending a voice message the senders voice is directly captured and sent to the recipient, there are cases in which a sender would want to send a message where the voice content of that message was obfuscated before it arrived at the sender.

This transformation will need to happen client side before the sending of a voice message, and the specific transformation applied should be modified by a randomly generated seed. This way when the voice message is retrieved the recipient cannot reverse the transformation because they lack the random seed to do so.

What means of obfuscation are you suggesting?

KeeJef commented 4 years ago

I haven't found a suitable library yet, but i assume it would be a combination of pitch shifting, treble bass, and tone modifications that were seeded by the RNG

I wonder if audio algorithms from Audacity could be used to process the audio.
