Testing Freshly Baked SSE FFT / MDCT Modifications
He wrote for his offspring an SSE implementation of integrated FFT and MDCT. The results even amazed me:
Two million 128-point complex FFTs and one million 512-point MDCTs were calculated. Intel® Core (TM) 2 Duo Processor E8400 @ 3.00GHz
I wonder if this can be sold or licensed to anyone. :)
