Thinking of tapes as simple sample recorder/players or even as some kind of adc/dac combination, they must follow the same rules as other samle players, that is: the max frequency they can record or play is Nyquist frequency, that is half sample rate. The shortest possible delay time then in theory is 1/nyquist[Hz] seconds.
Is it? Using a fractional interpolating all pass filter, you can't acheive delays less than one sample? Or does the allpass filter let you get fractional delays, but still the minimum delay is one sample?
