Is it possible to store a file in STM32F446's internal flash?

Greetings,

I need to upload an audio file containing an ECG signal to my stm32f446 nucleo-64 board, this file will be a .wav file or a simplified version of the .wav file containing interleaved audio samples from two channels. Since the .wav file or the samples file is too large, it is possible to upload it to the internal fash memory, using mbed? Or I need another software tool?

Tell the ST-LINK Utilities it is a binary file and write it directly into memory at the address you want to store it.

Too large for what?

The file is too large to store in RAM. It has about 256 kB.

I don't know how to use the ST-Link utilities, I can do that using mbed? How? 

Sorry, I don't know much about this platform.

you could try converting it to a .h header file and just ♯ include it.  declare it const and let the linker do what linkers do.
