[time-nuts] EFC tracking

[Raj]

Steve,

Large amplitude signals on the input ports tend to leak into the inputs on
sound cards. Isolation testing required!

>> Soundcards have inputs and outputs.  You can feed the output with a
>> series of samples that represent your control waveform.  The PC becomes
>> the oscillator and you know it's frequency and relative phase track.
