Does anyone know how to get fastest visual setup for Realtime audio analysis.That is so the audio coincides withh FFT etc.
Do graphics card have visual latency,like audio has?
Which driver is best used for graphics to achieve this.Open GL is meant to be realtime.
Thanks

Astroman has just advised a hardware unit in Wishlist forum, it must be the fastest and apparently not expensive.
