I have never been able to get Diffmaker to work correctly/not crash.
I am using Cool Edit just now, and I am not able to get a complete null with two copies of the same file.
I am getting differences between the filtered and nonfiltered files, but that is a moot point if I can't get a full null on the same file loaded twice ???.

Dan.

Forget cool edit, just do a binary file compare.
 
Now we are on to boats and rabbits are we? '-) I admit that hi end audio can be very expensive, certainly more than I can afford to purchase as well, but designing in that world is still exciting, and there are people who can easily afford to buy it, just like with boats and expensive automobiles.

Developer tip about using Diffmaker: keep the track sections under about 15 seconds. (It's in the manual, I believe).

The program uses a stupid amount of memory and stacks, which grow exponentially with track length, so gets in trouble easily with longer audio sections.

At some point of cost you hit 'good enough', then the law of diminishing returns kicks in.

There is that, but there is also marketing of "perceived value". I found out by experience that if you don't price something HIGH enough, it won't sell. Or if you give something away it gets ignored; charge a bunch for it and you can't keep it in stock. The point of diminishing returns can easily also be the point of diminishing actual value as well!

A real problem here is people who fear that they are going to be taken advantage of if they buy an audio product at the price stated. There have been and still probably are examples where a manufacturer purposely marks up a product's cost and gets away with it. But quality audio does cost real money to produce, no matter what somebody thinks it should cost. Just try it yourself in reality, to make something for more than just yourself and sell it in the audio marketplace. This is part of the essence of DIY audio. To make something yourself, for yourself, you might spend endless hours finding parts and putting them together, almost completely forgetting how much time and effort you put in to get something done. Yet, you might personally find it is worth, to you, much more than someone would actually buy it for. The true test is to make a number of the same thing, and all of a sudden it gets BORING, and you would like someone to help you make them. Then you have to find the space and equip and pay employees. Then you have to keep legal by getting a business license, etc, etc. Finally, you have to find an outlet to sell what you make and they have to get their percentage share. But that is not completely enough, then you have to advertise because even the best product still needs to be heard about by the public, so they are even aware of it. Sometimes you have to go to venues like hi fi shows that charge plenty for a room to show your product.
You see, it costs plenty just to make a quality audio product that people will actually buy. Perhaps more than you would be willing to pay for yourself, IF you did not make it for yourself. That is the advantage of DIY, but also a way to become short-sighted about the true costs of making a product.
THEN, there is also the problem of 'perception of quality' where you put your design in a cigar box or its equivalent to save money, and people pass it by, because they want a beautiful piece of furniture. This always puts the price up big time. And so it goes! '-)
 
Don't forget marketing costs, perhaps much more than the actual cost to produce the product just to get people to know it exists and to take the time to look at the product. Check out the cost for a years worth of full page color advertising in a magazine like Stereophile and most would be shocked I believe what it cost to market a product. With the internet things have changed some but then you have to drive people to your site and generate interest, not as easy as it sounds in the end.
