Processor in a Card

Sound4 takes the processor out of the box

French company Sound4 has done something unusual – it has taken radio processing out of the standard rackmounted box and put it onto a PCI Express card. The idea is that a PC-based processor is more open source and more flexible in deployment options.

Called Sound4 Voice AD, the card offers one to six channels, three bands of processing, four bands of parametric EQ, a three-band noise gate and a brick wall limiter.

The digital processing chain runs at 192 kHz. And, using a term not heard in awhile, the SHARC processors provide eight GFLOPs of processing power.

Analog and digital outputs are available. Presets can be saved. A Livewire version is also available.
