MSP430FR5994: The way to place the audio file in internal FRAM with even less memory consumption

Hi

Customer would like to place the audio file (.wav)  in internal FRAM.

Currently, they convert to c code by using the application on Host machine fist, and place the converted c code in internal FRAM.

Then, they would like to know whether there is any other better way to place the audio file in internal FRAM with even less memory consumption.

Any advice is welcome, so could you please provide the information?

Thanks and Best regards,

HaTa.
