NWin is a loudspeaker production test system using a standard soundboard. The user creates the tests they need and then combines them to create a test sequence. NWin can make sophisticated pass or fail decisions on frequency response (there are multiple measured frequency responses), polarity and other functions, and report on production performance.

You will need a PC fitted with a sound card, a microphone (possibly with a pre-amp), a power amp if your doing this seriously, and a loudspeaker to test.
