Cheating? Yes and no. First, remember we are dealing with numbers here, not an analog signal. As I understand it the same mathematical theoums that 16/44 CDs are based on allow these upsamplers to place more data points between the original points. Whether this helps the digital filtering or something else, I can't say. Instead of colorizing a movie, which is purely subjective, the analogy is maybe closer to using Photoshop to sharpen up a digitized photo. Nothing is added, but clearer distintions are made between black and white in areas that used to be grey. Is it as good as true 24/96-no. Is it better than 16/44-sometimes.Others have said it is really little more than an extension of oversampling, with which we have all lived with since about the year 1 CD. In that case, it would appear that the benefit is being able to use a filter with a flatter slope, which yields a more accurate analog reproduction.
Bottom line: does it work for you?
One inmate's opinion.
