inserting maybe 1 sample per 30000. I submit that nobody will notice
if you just insert a copy of an adjacent sample, and if you
want better than that, interpolation between two adjacent
samples would be even smoother.
I tried a more elaborate scheme some time ago (for Aeolus): instead
of just inserting on sample, replace N by N+1 samples using higher
order interpolation, with N up to 64. It could still be heard on some
sounds.
One way to resample accurately with ratios near to unity is to use
FFT based convolution to find the samples at fractional position
a/b and (a+1)/b, then interpolate linearly between those.
