Increasing window size

I’m currently coding a real-time audio effects library using the LPC4088 with the experiment base board to use the audio codec. I’m using the I2s protocol and I’ve noticed that the maximum window size is 32 samples in this case(max_fifo_points()).

Does anybody know if is it possible to increase this limit since I’m going to be needing a larger amount of audio samples to work on (let’s say 256)?

Thank you!
