TLV320AIC3254: Encryption of audio stream

Part Number: TLV320AIC3254

Hello,
customer want to use the mini DSP to do some encryption like calculation to make is less straight forward to retrieve the original audio data. To do so, they downloaded the PurePath studio and check the available blocks, unfortunately there wasn’t anything that allow us to manipulate the audio by ourselves. Do you know if they can define such blocks? They tried to ‘reverse’ engineer it by looking into the source code of these blocks. But they are all encrypted to that’s a dead end to.

Regards, Holger

  • Hi, HS,

    The blocks from PurePath Studio cannot be modified by end-user and there is no way to create a new block. Unfortunately, only the blocks available in the tool can be used.

    Best Regards,
