A set of LFO rate measurements have been taken, and compared to Godric Wilkie’s measurements, which can be found at this site. Again an fft based pitch detector [fiddle~] was used with a PD patch, although, this time, a successively smaller window size was used as the LFO rate was increased (512 - 128). This was to give the required time resolution. The smallest window size gave a time resolution of +/-3ms, and since the highest recorded LFO rate was 50Hz (wavelength of 20ms), this was considered sufficient.
There is some minor discrepancy between the results, and this should be investigated. A number of graphs have been attached showing the relationships between the two sets of results.
