I've run the standard Remex exchange program from Rabiner and Gold, and computed the coefficients required for a 48->44.1 filter (all 13001 of them). (I increased the program limits, and changed a few more things to double precision to help convergence.) This particular filter is +- 0.09 db to 20 KHz, and >100 db down at 22.05 KHz and higher. I'll try for a still better filter later. If you want the coefficents, send me mail and I'll mail them back.
