As long-term SOS readers will know, since 2010 Technical Editor Hugh Robjohns has been making regular use of an industry-standard Audio Precision (AP) audio analyser to perform spec tests and measurements during reviews. Hugh‘s APx515 is a pretty formidable piece of industrial test and measurement (T&M) kit, with a price tag to match — but anyone who would like a cheaper way to test audio gear themselves and already has an ASIO-capable audio interface now has a more affordable way to buy into the AP world. APx Flex (above) is a software‑only test solution that uses an existing interface for test signal I/O. The only hardware required is a dongle, the APx500 Flex Key, which is supplied with the software and connects via any spare USB 2.0 socket. APx500 Flex systems start at £2834.40$3000 for two-channel test software, and systems with a higher channel count for simultaneous testing of multi-channel kit are also available — contact AP UK for further pricing details.
