The output rate of a 3072 Interpolation, 1000 Decimation resampler is,
per definition, 3.072 of the input rate, because from every single input
sample, it generates 3072 intermediate samples, correctly
anti-image-filtering that , and from every 1000 intermediate samples,
correctly anti-alias-filtering that, it generates one output sample¹.

Do you understand what the resampler does, now?

Best regards,

¹ That's not what internally really happens, but it's mathematically
equivalent to that.
