Claim:
1. A method for processing an audio signal to influence the reproduction of the audio signal, comprising: sending a request to a server computer for a virtualization profile, wherein the request specifies a requested sample rate for the virtualization profile, and wherein the virtualization profile has a design sample rate and defines a digital audio filter; receiving from the server computer the virtualization profile with the requested sample rate; resampling a continuous-time bandlimited impulse response (CBIR) associated with the virtualization profile at the requested sample rate, wherein resampling the CBIR at a lower sample rate than the design sample rate results in fewer filter coefficients and wherein resampling the CBIR at a higher sample rate than the design sample rate results in more filter coefficients; and filtering the audio signal based on at least the virtualization profile by performing a convolution of the audio signal with the virtualization profile with the requested sample rate.
