Hello everyone.
So far I have used an old laptop combined with REW and LIMP, E-mu USB sound card, power amplifier and microphone. I do measurements and audio analysis, to study the boxes that contain the speakers I need impedance and SPL response graphs including THD and harmonics. Slowly I have transformed a small unused room into a simple unpretentious laboratory to do my experiments.
The time has come to retire my old laptop and replace it with something else. unlike what I have done so far, the new hardware will always remain in the room without ever leaving it and therefore I am not forced to buy another laptop. I will use two sound cards, one to measure the impedance and the other to measure the frequency response. this way I do not have to continuously assemble and disassemble the connection circuit every time I want to change the type of measurement. I ask you what could be the characteristics and specifications to take into account before proceeding with the purchase.
The following are some of the specifications that could become useful or even indispensable:
- at least 2 native legacy PCI slots in case I need to use internal sound cards like the RME 9632 HDSP. apparently, the best choice is a socket chip with native 32-bit/33 MHz support.
- external PCIe card with dedicated controllers for each individual USB port (to reduce latency and improve communication with the processor).
- WIN7 support
I need hardware that can run the audio software and the driver of the old sound cards without problems. I could orient myself towards a computer already assembled and ready to use or buy a motherboard, CPU and accessories, power supply, RAM, video card and screen but there is a problem, I have no idea which product to orient myself towards.
Can you recommend me?
bye and thanks
