I have been working on the Digital Audio Wiki, which constitutes the end product for this project. As it stands, the wiki broadly covers the process of recording and creating digital audio, from the basic principles of sound propagation in air up to binary encoding. From these basics, it expands upon the options available in digital (as well as analogue) audio storage and distribution, as well as discussing some of the supporting theory. The central page entitled 'What is Digital Audio?' covers most of this information, but I have begun creating a large number of related pages for more detail on the specific topics it touches on. Thus far I am very pleased with how it has come out. The wiki can be found, in whatever state it happens to be in at the time of reading, here: http://digital-audio.wikia.com/wiki/Digital_Audio_Wiki
In terms of assessment for the product I believe I will attempt to complete the majority of the wiki's core content as soon as possible, and then publish it to the 'public' as best I can, alongside one more survey regarding the wiki's usefulness and clarity. This should aid assessors in evaluating the success of the product as agreed in my proposal.
Additionally I have begun collating the data collected from the listening test study which forms the other major element to the project. So far I have examined the data from the controlled listening tests, and the results are largely inconclusive, which is arguably a conclusion in itself. It appears that the majority of participants have serious difficulty telling any difference between most of the comparisons made in the test. This is an interesting (and actually, quite positive) result, although it differs from my personal expectations in some ways. If the online version of the listening test (which has gathered substantially more responses, while still being too few to be statistically significant) indicates similar trends then I will be satisfied to report that any concerns regarding perceived nefarious or negative effects of widespread digital audio data compression are largely without cause. However, this potential outcome still leaves plenty to be discussed.
