Re: No thats not an issue with Synchronous Rate Conversion

The "320/147" ratio was brought up by the late Julian Dunn of Prism Sound, which would indeed make this a "synchronous" conversion. The problem is I've yet to see the a 16/44 to 24/96 conversion actually implemented this way.....

I don't know where the term "zero stuffing" came from.... The upsampled signal is not "zero stuffed", but calculated using a mathematical process called "convolution," where a set of coefficients representing the "Fourier transform" (within a truncated time period or "window") of the brickwall filter function is first multiplied with the a set of corresponding values from the raw signal at a specific time, and then added together, to provide the "interpolated" sample value.
