(thought I had more questions, cant edit the title)

Hello

Code:
		copy_to_fft_buffer(buffer, prevblocks[2]->data);
		copy_to_fft_buffer(buffer+128, prevblocks[1]->data);
		copy_to_fft_buffer(buffer+256, prevblocks[1]->data);
line 109, should'nt it be ?

Code:
	
	        copy_to_fft_buffer(buffer, prevblocks[2]->data);
		copy_to_fft_buffer(buffer+128, prevblocks[1]->data);
		copy_to_fft_buffer(buffer+256, prevblocks[0]->data); <<----------------
