And I don't think this is the first time it was brought forth. Yours seems to be a little more refined, compared to what I recall...."I was getting pretty disappointed about how low the interest about this program seemed to be, and am glad to hear you got a chance to work with it."
Anything new is a tough sell.... Take for example HDCD encoded digital playback. It's the best sonic performance of any media I've heard, but it's been rendered as insignificant on the stage of audio.
"A few magazine reviewers have shown some interest, but not many DIYers or non-pro hifi people."
I think half the problem is the device may show differences.... But what do you do with the resultant difference after that? It's even difficult to correlate the specific differences heard by the listener to unique characteristics in the difference waveform. The difference is relative, so it's difficult to determine what is doing what.
Spectrum analyzer software should be included in the package to maybe make such differences easier to resolve, in regard to correlation to design changes and correlation to specific subjective sonic characteristics.
"Rather surprising, given all the verbage that goes around about audibility, cables and DBTs, I thought more people would be interested in hearing more than just opinions."
While I agree, the question becomes what does one do with the difference waveform? The only purpose, to my knowldedge, is to maybe establish a data bank of these plots with corresponding "passed" and "failed" DBTs, to maybe establish thresholds of difference audibility. Useful later-on to predict expected DBT results. And maybe save time if the differences are small enough where a given DBT is an absolute certainty to fail.
I think it is also useful in determining how much the output signal is altered relative to the input signal. (Level matched and time-aligned.)
One person who might be interested in a product like this is an audio designer in Phoenix named Don Allen, who combines listener evaluation and objective testing in his designs. And a device like this may save time in regard to maybe predicting less-than-favorable evaluations. And since he is busy with a ever-growing customer base, saved time would be like gold to him.
