Is there a point to use the free True RTA software? For one the web site mentions that sound card calibration is not available in free version. Second, the RTA resolution is 1 octave. I assume this means I can take a reading at say 4, 8, and 16KHz, but nothing in between which seems like very coarse. Is this enough to do some basic tuning, or should I buy version with 1/3 or 1/6 octave resolution?
