Great application to adjust phono azimuth

I used this application to adjust azimuth with the HiFi News test record. It worked beautifully. Also useful to monitor recordings on my laptop or check phase while mastering. Very simple useful application.

this is a great little meter

Coming from windows I was looking for an audio meter just like the "Pinguin" audio meter program. The only thing I noticed it a has a little tiny delay to it. but not to bad. that is the only issue I noticed. I have an M-Audio USB pluged in to my mac book pro 2011. all in all worth the money. the pinguin program for mac is around 300 bucks and have to have a usb dongle.. so this might be your best bet.
