Cheap audio spectrum analyzer Hi list, Do you know of a cheap audio 
spectrum analyzer I could buy to check 20-20khz frequency response on 
audio stuff ? That would includes sinus generator + analyzer in the same 
box. I checked on eBay and most analyzers are RF band based and are so 
$$$$$ expensives. But 2 things: - I don't want to use analysis software 
on a separate PC - Any DIY projects with micro/graphic LCD would do.. I 
want a standalone analyzer. Thanks
