RX's Resample module allows you to convert an audio file from one sample rate to another. With iZotope SRC's steep low-pass filter, users can completely avoid the common aliasing artifacts while maintaining the maximum frequency content.

New Sampling Rate - This setting chooses the sampling rate you want to convert to. Choose a sample rate from the drop down list, or click on the field to type in another sample rate
Filter steepness - This allows you to control the steepness of the SRC filter cutoff. The white line is representative of an "Ideal filter".
Cutoff shift - SRC filter cutoff frequency shift (scaling multiplier)
Pre-ringing - SRC filter pre-ringing amount in time domain (0 for minimum phase, 1 for linear phase)
