It is not unusual that professional music artists run into performance barriers even with the most powerful computers today. Multi-track recording still is a challenging and sometimes frustrating task. James Cann from BionicFX in Massachusetts however noticed that audio processing task does not have to happen just in the CPU. His Audio Video Exchange technology (AVEX) converts digital audio in graphics data and then performs effect calculations using the 3D architecture of Nvidia GPUs. Compared to the capability of just six GFlops of a typical CPU, Nvidia's chips can reach more than 40 GFlops, according to Cann.
