Now if only I could hardwire it into my cerebal cortex
A soundman friend I used to tour with made a neat little gadget for us while traveling (I did monitors touring with him for a while, he did FOH). It was a little blue box that had a small speaker, one button, and one LED display. You pressed the button, it output 5 seconds of a random frequency (one of the middle 18 or so frequencies in a 31 band EQ, think it's range was around 160hz-12k or so). You pressed the button the second time and it showed the freq it played on the display. Was the best sound geek toy ever. Not sure whatever happened to it
We got pretty good at guessing frequencies quite quickly! Besides while you're driving for 5 hours at a time it gave us something fun and geeky to do!
