RPM Measurement App
Was searching for platter speed measurement tips online, but came across information about using cell phone apps to calculate RPM.
Downloaded a free app from app store, then paid $5 to enable some "advanced" settings. After 1 minute, I own a very good tool Tested my 3 turntables, and got 32.8, 33.5 and 33.4. They all confirm to what I hear. Pretty amazed about what a cell phone can do on turntables, except for bubble level. |
