The problem with the swept-sine method is that you now need
a perfectly omnidirectional and perfectly flat response sine wave
source. The problem with the impulse excitation method is that
you need a perfectly omnidirectional and perfectly shaped impulse.

Actually, the real problem is that the impulse response is necessarily
different from each instrument or performer. What arrives at the mic
is a summation of these different responses. This means that the
deconvolution will necessarily be an approximation.

That's a different problem and it's the same no matter WHAT
method you use to record it.

My point is that it's more-significant than the technique you use to
measure/compute the impulse response.
