Default new technique to measure audible distortion and signal degradation

a new technique in most details was realized in 2007-2008 years.
Later I looked for the more simple approach or modification, but now think that described maybe single one.

Text is not ready to the end, and not smooth.
Now feel kind of flu but not finished work does not give me a rest, and decided to put as is at the moment and finished later.
The description of the technique in main is present.

Comment, critics are welcome!

Best wishes
Mikhail

Hello Kulish Mikhail,

I am no expert in software / measurement, however it is nice to see new developments.

I know this is an appropriate forum, however the people who are most likely to be interested are in the Solid State part of the forum. So you may want to let them know?

Default Interesting!

Hello Mikhail,

The technique you describe is certainly interesting and very creative thinking!
I will follow this with interest, to see what you come up with.

I do have a comment not on the technique itself but the presentation. The way you decribe it it is a mix of a new distortion measurement method and some statements about audibility of distortion.
I believe you can make a much better and stronger case for your technique if you focus on that and not on other side-issues. Audibility of distortion is a completely different issue and is also controversial, mixing it in with your technique will weaken it.

Ideally, you could describe your technique, present measurements and then compare these measurements with traditional measurement methods. It would be very interesting to see if your method shows things better than we could until now.

regards,

jd

Very interesting reading. Its refreshing to see new ideas on how to measure what we obviously can hear. Are there any plans to implement the mathematics in software form ?

Thanks a lot for comments.
Will add some more to text and than will rearrange it all, to make it better structured and organized by sense.
Do not have at the moment a finished (ready to use) software but working parts of it.

Comment and remarks are very helpful and important, thank you.
Mikhail
