2 wishes for old school engineers

Hi,
Love the software, use it everyday for the last few years

1/ I would love to be able to measure wow&flutter of tape machines .basically a known frequency is recorded to the machine, and when played back there is a measure of this frequency, which shows up slow (wow) and fast (flutter) deviations in the speed of the tape transport

2/ a simple multi-meter display of the phase difference between input A and B, useful when aligning the heads on a tape machine.

Yoddom

Thank you for the suggestions.

1. It will be considered in future version.

2. There are two methods to measure the phase difference between the two channels.
(1) Use the phase spectrum together with the cursor reader to read the phase difference at a particular frequency.
Example:

(2) Use the "Harmonics" option in the Spectrum Analyzer to measure the phase of the fundamental frequency (refer to Section 3.3.2.8.3.5 of the software manual)
